How is Aura Botanica different from other brands?

Aura Botanica is a new professional luxury natural origin haircare range.

We have developed a range of 4 products for dull, devitalized hair composed of up to 98%* of natural origin ingredients on average:

- Micellar Shampoo formulated with 96% natural origin* ingredients and 99%** biodegradable
- Soin Fondamental formulated with 97% natural origin* ingredients and 99%** biodegradable
- Concentre Essentiel formulated with 99% natural origin* ingredients and 99%** biodegradable
- Essence d’Eclat formulated with 99% natural origin* ingredients and 96%** biodegradable

The formulas are sulphate-free***, silicone-free and paraben-free, with a highly biodegradable fragrance and 2 solidarity-sourced botanical oils: Samoan coconut oil and Moroccan argan oil.
With this launch, Kérastase tackled with success the challenge to offer a new hair signature, the “nude touch”, and the promise of healthy-looking glow that is complementary to its hair care DNA.

What is dull, devitalized hair?

Dull, devitalized hair is hair that lack in radiance and need to be nourished. It concerns the following hair types: normal to lightly sensitized hair that can be coloured, slightly frizzy, dry to the touch and neither too fine nor too thick.

What does the Aura Botanica range do to the hair?

The Aura Botanica range provides 48h durable conditioning, 72h anti-frizz and 3x shinier hair* thanks to proven highly efficient natural origin actives allied in powerful breakthrough sensorial formulae for a nude touch, lively hair and healthy glow. (*instrumental tests performed using Bain + Soin + Concentré)

Using Aura Botanica reveals the hair’s healthy glow by leaving hair that feels uncoated and weightless yet is deeply nourished with frizz control.

Why do Aura Botanica’s formulas contain high levels of natural origin ingredients?

At Kérastase, we are convinced that naturality and sustainability can meet performance and luxury. We have developed a whole range of products made of up to 98%* natural origin ingredients that deliver high performance with great visible results on hair and a highly sensorial user experience. Aura Botanica represents our belief that products with high level of natural origin ingredients can efficiently care for your hair, and better respect the environment.

In our formulas, natural origin ingredients are combined with a few synthetic ingredients, which are always of very high quality, to guarantee the quality and sensorial properties of our products.

A few other brands claim products achieving 100% natural origin ingredients. Why is this not the case for Aura Botanica?

Kérastase has made the conscious choice not to have formulas 100% of natural origin in order not to compromise performance. Despite this, the range achieves record high levels of natural origin ingredients (up to 98%* on average) and the Concentré Essentiel and Essence d’Eclat are the highest at 99% of natural origin* each.

The small % of the formula that is not of natural-origin ensures the high quality of the formula in terms of cosmetic usage and sensoriality, In the future, if formulae with 100% natural origin ingredients perform to the desired standards, the brand will most certainly integrate them into the platform.

We have heard that Kérastase built the formulation from scratch. Yet you use ingredients that are not new. So what exactly was new in the formulation process? Which natural origin ingredients are exclusive to Kérastase?

The point of Aura Botanica is not to have ingredients that are exclusive or necessarily rare. What is unique about Aura Botanica is that our laboratories had to start formulation from scratch respecting the strict requirements to develop formulas made of at least 96% of natural origin* ingredients, that are also highly biodegradable**, without silicones, sulphates*** or parabens, and with no compromise on sensorial experience and performance.

Why is Aura Botanica considered to be a prowess of formulation?

Aura Botanica has required more than 18 months of extensive formulation work that started from scratch; more than 50 formulas were developed, to obtain the best candidates meeting each of the following very demanding requirements:
• High levels of natural origin and biodegradability: formulas made of 98% of natural origin* ingredients, 98% biodegradable** in average and without sulphates***, silicones and parabens
• Luxurious sensoriality and pleasurable use: unique caring textures with an aromatic fragrance to indulge the senses and beautify hair naturally without weighing it down. For example, creating a sulphate-free***, silicone-free, high natural origin shampoo that delivers a light, airy, plentiful lather to gently yet efficiently cleanse the fibre.
• Uncompromising high performance: exceptional proven results such as 48h long-lasting nutrition, 72h anti-frizz/volume control/anti-humidity, healthy glowing hair that is up to 4 times shinier (instrumental tests after application of the Bain + Soin + Concentré) and stronger (instrumental test after application of Essence d’Éclat only).

How were the key ingredients in Aura Botanica chosen?

The botanical oils used in Aura Botanica, Samoan coconut oil and Moroccan argan oil, were chosen for 3 major reasons:
• they have complementary fatty acids
Samoan coconut oil is particularly rich in lauric acid (saturated fatty acid). Moroccan argan oil has been used for centuries by the Berbers living in the Atlas Mountains for its richness in nutritive lipids like omega-6 (poly-unsaturated fatty acids) and omega-9 (mono-unsaturated fatty acids).
• their proven performance on hair
Studies in advanced research labs prove that Samoan coconut oil, thanks to its richness in lauric acid, is able to anchor itself and deeply in hair fiber. Its action on the fiber – inside and out – provides hair with protection, hydration, nutrition, suppleness, detangling.
In addition to coconut oil, Argan oil brings nourishing properties to dry and devitalized hair and its efficacy has been demonstrated on softness and shine.
• their natural, organic and fairly traded/responsibly sourced origin
Coconut oil is a virgin natural and certified organic oil that is cold pressed from fruit harvested in Samoa, a group of 9 islands in the South Pacific. The hand-gathered coconuts are sourced from a local NGO, Women in Business Development (WIBDI). Through this project, nearly 100 Samoans receive regular income, which enables them to stay on the island and invest in health and training programs.
Argan oil is natural and organic, extracted by pressing the nuts after cracking them by hand. These nuts are harvested carefully in the argan forest, a vast territory of 8000 km², listed by UNESCO as a biosphere reserve. Targanine, a cooperative of 334 women in southwest Morocco, teaches women how to harvest the argan fruit while respecting the forest, participates in reforestation and organizes literacy programs.

Aura Botanica uses the same ingredients (coconut oil and argan oil) that have been on the market for years. So how can performance be different in these products than all the other products that contain these ingredients?

What is unique about Aura Botanica is that natural origin ingredients are the driving force for each formula. For example, rather than replacing sulphates in the shampoo with a chemical surfactant, Micellar Shampoo employs three natural-origin surfactants to cleanse away impurities from the fibre.

Furthermore, they are not just any coconut and argan oils, both are responsibly sourced as part of L’Oréal’s Solidarity Sourcing programs that ensures not only a fairly traded price for the oils but also commits to a quantity over time helping local communities foster sustainable livelihoods.

Why is Aura Botanica positioned at a price premium?

Ensuring a fair and sustainable price for the ingredients we use means that the costing of the formulas is quite high to manufacture. Furthermore, the experience that we have with Aura Botanica sets it as veritable luxury products. Lastly, there is a true unicity to what Aura Botanica proposes, that sets it apart as being a range able to have formulas with very high levels of ingredients from natural origin (98% natural origin on average) and biodegradability, which have assured quantifiable and proven performance, with ethical sourcing and all with a premium fine fragrance, indulgent textures and a veritable luxurious product experience. For professionals or consumers, Aura Botanica is our definition of natural luxury.

Why does Kérastase believe that products inspired from nature, biodegradability are important?

Kérastase is committed to becoming a responsible luxury brand. In the past years, we have made strong headway, as we have engaged to improve the environmental profile of both our formulas and packaging for all new product developments.

Why is Kérastase launching a range of produtcs with high level of ingredients from natural origin?

Kérastase is committed to responding to consumer’s needs and desires. We recognize that there are women to whom naturality is important, but this is not a reflection on all of our consumers. Aura Botanica will continue to be our bastion of Natural Beauty. Kérastase will continue to integrate the values of sustainability into all its products but knows that there are limits as to what nature can do, and for hairdressers or consumers in search of pure performance we will still deliver effective formulas that are as conscious and sustainable as possible.
For over five decades years, Kérastase has been inspired by nature and has included the fine, botanical ingredients in the formulation of its groundbreaking products. The 1970s saw the invention of Kéraplasma, the brand’s original plant-based hair balm. In 1980, Kérastase introduced the world’s first hair mask, Masque Kérastase à l’Huile de Germes de Maïs, enriched with maize germ oil. One year later, its first protective hair oil, Soin d’Huile Végétale, was created. In 2010, the golden Elixir Ultime signalled a new era of opulence in hair oils. Since 2013, iconic Nutritive formulas have been infused with the intense, nourishing power of iris rhizomes. Today, Aura Botanica reinforces the brand’s commitment with a complete range of products with high degrees of natural origin.

What gives the Aura Botanica products their color?

None of Aura Botanica’s products contain any artificial colorants.
The Micellar Shampoo and Soin Fondamental get their color from caramel, a natural origin botanical ingredient. The Concentré Essentiel and Essence d’Eclat do not contain any colorants.

What ingredients allow the Micellar Shampoo to give that squeaky clean feeling?

Micellar Shampoo is formulated with natural and renewable origin surfactants (Coco Betaine, Coco Glucoside, Sodium lauroyl Sarcosinate) and not with any silicones or cationic polymers that are usually present in shampoos to give hair an instant silky feeling. These natural origin surfactants allow the formula to provide effective yet gentle cleansing which translates into the squeaky clean feeling. When paired with the Soin Fondamental (modulated or not with the Concentré Essentiel) balanced care is achieved to reveal healthy-glowing hair.

How come the Soin Fondamental does not weigh down hair? What specific ingredients cause the weighing down feeling in other products?

Soin Fondamental is formulated to be smart and deliver what the hair needs, no more, no less. To push cosmeticity further, the result can be modulated with the Concentré Essentiel if needed for more challenging hair types.

There are different agents that can make the hair feel weighed down, often it boils down to the way the products are formulated.

Aura Botanica is able to deliver its signature nude touch and healthy glow without weighing hair down because it has been formulated to have the ideal balance of natural oils to nourish hair while preserving weightlessness.

How do I use the Concentré Essentiel?

The Concentré Essentiel is a multi-usage product which application can be personalized according to ones need. It can be applied:
- As a pretreatment before the Micellar Shampoo on the length and tips of the hair to provide weightless care
- As a pretreatment on the scalp before the Micellar Shampoo to provide care to dry scalps
- As a nutrition booster mixed with the Soin Fondamental (advised ratio of 2 pumps of Concentré Essentiel for 10g of Soin Fondamental by the International Testing Room) - As a massage oil for the body to nourish and beautify the skin (please note that this product cannot be applied to the face)

Elixir Ultime is already a range with oils, what is the purpose of Aura Botanica?

The end benefit is perceivably different as Elixir Ultime provides sublime shine and the traditional Kérastase touch, whereas Aura Botanica delivers a soft healthy glow and hair feels nude to the touch. Furthermore, Aura Botanica is not restricted to only using oils, today we use them but in future developments other natural origin actives may be introduced.

Does Kérastase test on animals?

Kérastase, like all L’Oréal brands, does not test its products or any of its ingredients on animals, nor does delegate this task to others. Furthermore, cosmetic testing on animals is banned in the European Union, India, Israel and Norway.

What is a natural origin ingredient?

(As defined by the new standard ISO 16128-1), An ingredient is of natural origin if it is unchanged from its natural state or has been made using a process retaining more than 50% of its molecular structure from its original botanical (plants, algae ...) or mineral source.

What is the difference between a natural origin and a botanical ingredient?

A botanical ingredient finds its origin in botanical sources (flowers, trees, cereals, algae…), and its natural origin status is defined by the process used to obtain it.
If the process allows to retain more than 50% of its molecular structure from its original botanical source, a vegetal/botanical ingredient can therefore also be considered natural origin.

What is an organic ingredient?

An organic ingredient is defined by the new standard ISO 16128-1 (ISO = guidelines for technical definitions) as a natural ingredient originating from organic farming methods or from wild harvesting.
For example, the coconut oil and argan oil are certified organic ingredients present in all Aura Botanica formulae.

Then, are AURA BOTANICA formulas certified organic?

A product can be certified organic by an external labelling organization if the standards of the said organization are met. It is more difficult to be certified organic, as there are no exemptions for certain ingredients / some synthetic ingredients are forbidden. Also, a minimum level of organic content must be met and varies according to the labels, for example 10-20% for the European standard COSMOS. Aura Botanica’s formulas were not developed to be certified organic but rather contain certified organic ingredients.

What is biodegradability?

This is the capacity of organic molecules to be quickly and entirely broken down by the action of micro-organisms. It is measured with an internationally recognized method defined by the OECD (Organisation for Economic Cooperation and Development).

What is the percentage of biodegradability in each AURA BOTANICA’s products?

As Kérastase is committed to becoming a responsible and sustainable luxury brand, all Aura Botanica formulas are at least 96% biodegradable* making it Kérastase’s range with the highest average levels of biodegradability:
- Micellar Shampoo: 99% biodegradable formula
- Soin Fondamental: 99%* biodegradable formula
- Concentré Essentiel: 99%* biodegradable formula
- Essence d’Éclat: 96%* biodegradable formula
*test OECD 301 or ISO equivalent

What is a renewable ingredient?

Renewability of an ingredient is defined by its level of carbon content from botanical source, which must be above 50% of its total carbons to consider the ingredient as renewable.
A renewable ingredient is therefore a botanical ingredient.

What is a green chemistry ingredient?

It is an ingredient transformed according to the 12 principles of green chemistry that can be summed up in 3 key points:
- renewable origin (at least 50% carbon content from a botanical source)
- made according to an eco-friendly process, respectful of the human and environmental safety - with a low impact on the environment (no bioaccumulation, high biodegradability, low water footprint)

What is a responsibly sourced ingredient?

An ingredient can be qualified as responsibly sourced if it meets the following criteria: has a traceable origin, its supply network respects critical points (i.e. respecting Human Rights respect…), is validated by a third party, and has positive social impact on a community.
For example, the argan oil and coconut oil present used in Aura Botanica products are responsibly sourced ingrediens, both are also part of L’Oréal’s ‘Solidarity Sourcing’ program launched in 2010.

How is the production of Kérastase’s formulas respectful of the environment 
Kérastase’s production plant has reached carbon footprint neutrality since 2015, combining the use of biomass, photovoltaic technology and trigeneration energy. For the first time, a trigeneration facility has supplied steam, hot water, cold water and electricity to a manufacturing site and produced 100% of the energy needs for its manufacturing and packaging processes. In addition, the biomass plant has photovoltaic panels which provide the electricity necessary to achieve carbon neutral status since 2015.

What about the outer packaging of Aura Botanica’s products, is it recycled?

For the Micellar Shampoo, retail 250ml and travel size 80ml bottles contain 100% recycled PET plastic – the first of Kérastase bains to achieve this.

The cartons of the Concentré Essentiel and Essence d’Éclat are made using FSC-certified cardboard. FSC (Forest Stewardship Council) certification ensures that products come from well managed forests that provide environmental, social and economic benefits.

Why is some of Aura Botanica’s packaging not made with recycled material?

Today, there are not large enough recycling circuits for all raw materials used to manufacture packaging. We are currently challenging all our suppliers to make a shift and start sourcing recycled materials that could be integrated in the other products in the near future.


What are silicones in hair care?

Silicones (ingredients with the suffixes –methicone or –siloxane) are types of polymers that are inert, synthetic compounds.
There are 2 main types of silicones:
• Dimethicones
o AMODIMETHICONE or amino-silicones are smart silicones that stick to hair and help repair the damaged parts of the hair strand that are negatively charged (amino-groups are positive and the two attract one another). They also favour hair detangling and are excellent conditioners.
o DIMETHICONES bring shine, softness and smoothness to the hair. They have excellent light reflexion properties and help to reduce frizz.
• Siloxanes are low-molecular weight compounds widely used in numerous industrial sectors (household cleaning products, medical articles, cosmetic products, etc.). This group consists of a number of substances of which volatile cyclic siloxanes such as cyclotetrasiloxane (D4), cyclopentasiloxane (D5) and cyclohexasiloxane (D6). These raw materials are endowed with unique physicochemical properties (no oudor or color) enabling various cosmetic performances to be achieved (non-oily and silky feel, ease of product application on the skin and hair, rapid product drying). Siloxanes D4, D5 and D6 are also widely used in a large variety of cosmetic products (skin care, makeup, hair care).

More data on siloxanes:

What is the role of silicones in haircare products?

Silicones are used for their unique properties to bring shine, softness and smoothness to the hair. For example, in shampoos, silicone supplies shine and softness without adding weight.

They are water-repellent and help create a fine layer that coats the hair strand and seal out humidity. They are also very good conditioners.

The reasons why silicones are largely used are that they don’t interact with other formula ingredients (e.g. they can be mixed with other conditioners or surfactants very easily) and they don’t affect hair fibers and proteins (e.g. keratin) with their very mild action. They also do not hinder other treatments that are often done to hair (e.g. colouring, perming etc.) but they instead protect (and repair) everyday hair damage by keeping hair soft, nourished and manageable.

Why then are some products silicone-free?

From a sensorial standpoint, some consumers prefer silicone-free products, as they offer a specific sensorial signature with a different hair touch and appearance, a “squeakier” clean touch for shampoos, a more natural conditioning effect (firmer touch), a less coated finish.

Also some hairdressers and colorists prefer a “less coated” fibre before applying hair colour, or another treatment which is considered easier with a silicone-free product.

This is why Kérastase has developed a new range of silicone-free products in Aura Botanica offering 'nude touch' to complement its existing product offering.

Are there good silicones and bad silicones? Or some that are best to avoid and others that are better for the hair?

Silicones present in Kérastase products present no danger to the users and are adapted to the cosmetic needs and expectations of the consumer target.

Why do silicones have a negative reputation?

Some people have pointed out the build-up effect of silicone coating. This is unproven because silicones, when used in well formulated products, do not build up on hair fibres.

Are you sure silicones do not pose any health risks?

Safety of both ingredients and formulas is a cosmetic prerequisite. Kérastase has been safely using silicones for decades into hair care products. Before introducing an ingredient in a formula, it has to undergo a rigorous safety assessment. We determine the right level. We offer products that are safe, effective, with high quality that can be used in complete confidence.
For more information, please visit:

Can silicones have an impact on scalp, hair loss or hair thinning?

Some people have pointed out the negative impact of silicones on scalp or on hair. However, there is no known scientific evidence to justify this hypothesis.

Do silicones have an environmental impact?

Silicones are safe for the consumers but not easily biodegradable in the environment.
So, our laboratories are working to find new types of silicones which can be used in smaller quantities and with greater biodegradability or alternatives to silicones with similar end benefits on hair and a better environmental profile.


What are sulphates?

sulphates (aka Ammonium Lauryl sulphate, Sodium Laureth sulphate, Sodium Lauryl sulphate (aka Sodium dodecylsulphate), Sodium Lauryl Sulfoacetate, Sodium Myreth sulphate, Sodium Myreth sulphate) are surfactants, substances that reduce surface tension between two media (two liquids or a liquid and a solid for example) and therefore contribute to the emulsifying, foaming and/or wetting effect and to detergent efficacy of cosmetic products – notably shampoos & cleansers.

What is the role of sulphates in haircare products?

sulphates are detergent ingredients that contribute to the deep cleansing efficacy of shampoos, helping remove dirt, impurities, etc.

They are also good foaming agents to provide generous pampering lather during use and make the product simple and easy to rinse off.

When did sulphates start to exist in haircare?

In 1934, L’Oréal made a revolution in hair care products with the launch of the 1st mass market shampoo without soap. Soap indeed dried hair out, making it dull and difficult to detangle. Based on sulphates originating from fatty acids, this shampoo was first a powder to dilute in water. In the late 40s, its formula was reworked to become a ready-for-use cream.

sulphates have been used by Kérastase in its cleansing haircare products to develop well-balanced formulations, adapted to the cosmetic needs and expectations of the different consumer hair types targeted by our ranges.

Are there good sulphates and bad sulphates? Or some that are best to avoid and others that are better for the hair?

sulphates used in Kérastase products present no danger to the users and are adapted to the cosmetic needs and expectations of the consumer target.

Why do sulphates have a negative reputation?

sulphates, like any other ingredients in our formulas, are always carefully selected and comply with strict mildness requirements to develop the best products.
sulphates have largely been used for many years in hair and skin rinse-off formulas. They now have a long history of usage confirmed by the numerous clinical data validating their good tolerance at the levels used in our formulas.

Are sulphate free formulas really gentler on hair? If so why?

All our formulas, with and without sulphates, are developed to respect hair integrity, whatever the type of hair.

Are you sure sulphates do not pose any health risks?

Safety of both ingredients and formulas is a cosmetic prerequisite. L’Oréal has been using safely sulphates for decades in hair care products. Before introducing an ingredient in a formula, it has to undergo a rigorous safety assessment. We determine the right level. We offer products that are safe, effective, with high quality that can be used in complete confidence.
For more information please visit:

What is their impact on hair color?

Some people have pointed out the negative impact of sulphates on hair color. But, today, there is no known scientific data to confirm this hypothesis/we are not aware of any scientific evidence to justify this hypothesis.

Why then are some products sulphate-free?

sulphate-free formulas have also a different sensorial signature. With sulphates, foam is even lighter, more abundant.

What are sulphates replaced with in sulphate-free shampoos like Aura Botanica?

In Aura Botanica’s shampoo, there are 3 complementary surfactants:
- Coco betaine
- Coco glucoside
- Sodium lauroyl sarcosinate
They have been selected based on their natural and renewable origin (mainly originating from coconut) and specifically combined together to provide effective yet gentle cleansing while delivering a lightweight lather for healthy glowing hair.

Do sulphates have an environmental impact?

sulphates have a limited impact on the environment. Our laboratories are continuously working to find new types of surfactants with a better environmental profile and a greater biodegradability.


What are preservatives? What are they used for?

Preservatives are substances of natural or synthetic origin whose principal role is to prevent physicochemical degradation and growth of microorganisms (bacteria, yeasts and fungi) in cosmetic products. Most preservatives are synthetic substances belonging to various chemical groups (halogen-containing compounds, aldehydes, parabens, glycol ethers, organic acids). Preservatives are also very widely used to prevent microorganism contamination of foodstuffs and medicines. Preservatives are absolutely indispensable for ensuring the protection of certain categories of cosmetic products (lotions, creams, etc.) since microorganism contamination may occur during manufacturing (water, air, packaging materials) or during repeated use by the consumer. Cosmetic products have a long shelf life (6 to 24 months after first opening) and, unlike perishable foodstuffs, are stored at room temperature. A cosmetic product that is poorly protected and contaminated may induce health risks for the consumer.
For more information, please visit:

What are the preservatives agents in the Aura Botanica’s products? Why were these particular ones used?

Two preservative agents, salicylic acid and sodium benzoate, are used in Aura Botanica’s products. They were rigorously selected to guarantee the microbiological protection of the products during their lifetime.

If salicylic acid and sodium benzoate are the preservatives and are just in the Micellar Shampoo and Essence d’Eclat, does that mean the Soin Fondamental and Concentré Essentiel do not have any preservatives in them at all?

The Soin Fondamental and Concentré Essentiel have formulations which do not require the addition of preservatives to guarantee their microbiological protection of the products during their lifetime.

What are the potential risks?

Despite the essential role of preservatives in the protection of cosmetic products, their benefit is regularly contested. Preservatives are accused of inducing allergies and playing a role in the emergence of certain forms of cancer, and are singled out as endocrine disruptors.

The number and concentration of preservatives used in cosmetic products are very limited and strictly controlled by numerous international regulations. The safety data on those preservatives are very regularly reviewed by the scientific experts of the international health authorities in order to take the most recent studies into account. The concentrations used in cosmetic products may then be adjusted in order to prevent potential impacts on consumer health.

Why is the protection of L’Oréal cosmetic products safe?

We use a very limited number of preservatives selected for certain specific categories of cosmetic products when protection against microorganisms cannot be ensured by any other means. The preservatives and their concentrations are rigorously selected to ensure the correct level of microbiological protection of the product under study, in strict compliance with the international regulations, while ensuring perfect safety for the consumer.

We have also developed a proactive innovation strategy in the field of the microbiological protection of formulae consisting of: 1) synthesizing new preservatives endowed with an irreproachable safety profile and 2) developing specific packaging systems and new formulations that are not vulnerable to microbiological contamination.

What are parabens?

Parabens are a series of preservatives that are very widely used to ensure the protection of foodstuffs, medicines and cosmetic products from microbiological contamination (bacteria and fungi). The parabens used in cosmetic products are of synthetic origin but they also exist naturally in certain foods such as red fruit, vanilla, carrot and onion, and in foodstuffs prepared from plants, some cheeses, products produced by bees (propolis, royal jelly) and in the human body.
For more information on parabens, please visit:

Why are parabens indispensable in certain cosmetic products?

Parabens are very useful for ensuring the protection of numerous categories of cosmetic products (lotions, emulsions, creams) since they are very effective at low concentrations against bacteria and fungi, are heat-stable and act synergistically with other preservative groups.

In this group, ethyl and methyl parabens (short chains) are the most widely used, frequently in combination, while butyl and propyl parabens (long chains) are less used.

What are the potential risks?

The use of parabens in cosmetic products has been controversial for several years. Due to the ability of parabens to bind to oestrogen receptors in vitro, the preservatives were suspected of a potential effect on reproduction in humans and on oestrogen-dependent cancers such as breast cancer. The affinity of parabens for the oestrogen receptor is, however, approximately 1 million times weaker than that of the oestrogen (estradiol-17ß) present in the human body and no impact on human health has been formally demonstrated to date.

Are there parabens in Aura Botanica products? Why?

Aura Botanica formulas are paraben free, as there were alternative options adapted to the type of formulas and without any trade off on products quality and tolerance.
More info on parabens:

Are there parabens in Kérastase products? Why?

Some Kérastase products still contain parabens. Parabens have been used for several decades in certain categories of our cosmetic products and only when indispensable to ensure effective microbiological protection.
More info on parabens:

Why are L’Oréal products containing parabens safe?

The scientific experts of the various international health authorities very recently reviewed all the toxicological data available on the 4 parabens (ethyl, methyl, propyl and butyl parabens) used in cosmetic products and confirmed that they could be used in all safety by consumers, while adjusting the concentrations for use of each of the parabens. We never compromise on the quality and safety of our products. Microbiological protection is one of the components of product quality and safety. Parabens have been used for several decades in certain categories of our cosmetic products and only when indispensable to ensure effective microbiological protection. The products then mainly contain ethyl and methyl parabens, which have a particularly positive safety profile. The concentrations of those parabens are rigorously defined in order to procure the correct level of microbiological protection for the product under study, in strict compliance with the international regulations, while ensuring perfect safety for the consumer. We have also developed an offensive innovation strategy designed to develop specific packaging systems and new formulations that are markedly less vulnerable to microbiological contamination, thus enabling limitation of the use of preservatives, including parabens.


Fragrances are the constituents of olfactory compositions which create the basis of the great perfumes, eau de toilette, etc. Fragrance ingredients are also used in household fragrances, to perfume cosmetic products and in consumer products such as household cleaning products.
Since ancient times, man has made use of and traded in fragrances. The role of odours in social relations and well-being is well known. Olfactory compositions underlie the odours of cosmetics and contribute to the sensory pleasure related to their use. Fragrance ingredients include a very large series of substances of natural origin (rose, jasmine, lavender, orange, bergamot, etc.) or synthetic origin.
For more information on fragrance ingredients, please visit:

Why indicate 'Fragrance' in the list of ingredients and not the names of the substances?

The creation of olfactory compositions draws on a unique experience and perfumers jealously guard the recipes of the great perfumes on which their celebrity is based. In order to comply with the confidentiality necessary for the protection of industrial know-how, the composition of the fragrance is not indicated in detail on the labelling, with the exception of the list of allergens contained in the fragrance.

Is the fragrance in Aura Botanica natural?

Aura Botanica’s fragrance has been designed to be eco-friendly by having a high level of biodegradability. Achieving this would not be possible with natural fragrance components that have low biodegradability levels.

Does Aura Botanica fragrance have aromatherapy benefits?

Aura Botanica’s fragrance contains several essential oils, which are at the basis of aromatherapy, with invigorating and stimulating benefits, to help enhance the well-being of the mind, body and spirit.

What are the potential risks?

Fragrances are known by the dermatological community as being liable to induce allergies in certain consumers. In 2003, the European Union instituted, in the cosmetic regulations, the obligation of indicating, in the list of ingredients, the presence of certain substances rather than the simple statement 'fragrance'. In all, 26 substances considered the most allergenic are to be stated in the product labelling if present above a certain cut-off (0.01% for rinse-off products and 0.001% for non-rinse-off products). The consumer, who is thus better informed, is able to ensure the rational use of the cosmetic product. The European Scientific Committee on Consumer Safety recently reviewed all the scientific data on allergies related to fragrance ingredients in cosmetic products and recommended extending the list beyond the 26 substances that currently have to be stated in the labelling. The European Commission is working in close cooperation with industry to define the optimum manner of incorporating the expert opinion in new labelling provisions.

Why are L’Oréal products safe?

In our research teams, certain staffs are specifically responsible for assessing the safety of fragrance ingredients. The olfactory compositions that we purchase comply with the standards of the IFRA, the international organization representing the producers of olfactory compositions, and undergo an initial safety assessment by the supplier. In addition, the compositions are required to comply with very strict in-house specifications to which the safety assessor contributes. After having checked that the composition fulfils the regulatory obligations and safety requirements, we conduct clinical tests in order to confirm the safety of the product containing the fragrance composition. The dual assessment by both the supplier and L’Oréal ensures that our products can be used in all safety.


What is an allergen?

Allergens are substances that are foreign to the body and that may induce, in certain subjects, after several contacts, an exaggerated response of the immune system known as an 'allergy'. Allergens are naturally present in our environment and diet. For example, pollen or the mites in dust may give rise to asthma; peanuts, shrimp and strawberries are known to induce allergic reactions that may potentially be very serious. Lastly, synthetic ingredients may have allergic potential. This is the case with certain medications, colorants, fragrances, etc.

Several types of allergies are to be distinguished, among which the best known are immediate allergies, mainly food allergies, which may be very severe, and delayed contact allergies, which gives rise to cutaneous symptoms (redness, itching, etc.) that may be extensive to a greater or lesser degree.

What are the risks with cosmetics?

Cosmetic products may occasionally give rise to allergic reactions, mainly contact allergies. The reactions are due to the presence of ingredients such as certain hair colorants, preservatives and fragrances (cf. datasheets). The reactions are rare, generally confined to the product application site and totally reversible on discontinuation of product use. The reactions may necessitate dermatological consultation and an appropriate treatment.

Why are L’Oréal products safe?

The ingredients that we use in our products have all undergone rigorous evaluation of their allergenic potential. When we evaluate cosmetic product safety prior to marketing, we verify that the ingredients constituting the product are used under conditions in which they will not induce allergies in consumers. Lastly, we verify the absence of allergic reactions by conducting appropriate clinical trials on our products. This rigorous approach covers all the products that we develop.
In rare cases and for very specific products, when an allergic risk is known and cannot be totally eradicated with the current state of scientific and technical knowledge, we inform the consumers of the risk incurred via the product labelling and we propose a method of detecting allergic potential before product use. This is the case for hair color products, for which we recommend systematically conducting a cutaneous allergy test 48 hours before coloration (see hair colorants). It is to be noted that we pioneered the recommendation of this test.

In general, we recommend that consumers who know themselves to be allergic read the list of ingredients in the labelling of all cosmetic products attentively in order to avoid use of products that contain the ingredient(s) responsible.


What is gluten? Does L’Oréal use gluten?

Gluten is a mixture of substances, mainly consisting of proteins, present in the seeds of certain cereals such as wheat, barley, rye and oats. Gluten is present in numerous foods containing those cereals. It is used for its viscoelastic properties, particularly in baking.

We do not use gluten as an ingredient in our cosmetic products. Despite our high level of requirements relating to the quality of our raw materials, small traces of gluten may be present in a few of our raw materials derived from wheat, rye, barley and oats.

What are the potential risks?

Intolerance of certain protein fractions of gluten, also known as celiac disease, is relatively common in humans. The intolerance is characterized by marked impairment of the walls of the small intestine, which may interfere with the intestinal absorption of certain essential nutriments, thus resulting in serious deficiencies. The disease is induced by intake of foodstuffs derived from rye, oats, wheat or barley. Treatment necessitates life-long compliance with a gluten-free diet.

Why are L’Oréal products safe?

We decided not to use gluten as an ingredient in our cosmetic products. Traces of gluten in certain raw materials may be present in some cosmetic products in tiny proportions. The exposure of the human body to those very small quantities of gluten is not associated with a consumer health risk, even in consumers presenting with celiac disease. Ingestion, even accidental, of lipstick containing a few traces of gluten cannot induce adverse effects because the quantities of gluten are so small.

Consumers who know they have gluten intolerance rightly wish not to use cosmetic products containing ingredients derived from the incriminated cereals. Before choosing a cosmetic product, consumers may very easily verify the absence of the Latin names of the cereals involved in the list of ingredients (wheat: Triticum vulgare; barley: Hordeum distichon; oats: Avena sativa; rye: Secale cereale).
