BHT
Where does it come from?
In cosmetics, BHT is of synthetic origin. BHT is formulated in the laboratory.
What is it used for?
BHT is used in various cosmetic products, including certain formulas containing fats or in aqueous emulsions containing certain active ingredients or plant extracts. It is used in certain products to stabilize and protect the raw materials themselves, and less as an ingredient in and of itself. It can resist to high temperatures (unlike some natural antioxidants): it is therefore very useful in certain raw material manufacturing processes. YSL beauty exceptionally uses it as an ingredient for its antioxidant properties, helping to protect the products of oxidation and ensure the quality and stability of formulas
Why is it questioned?
BHT is accused of being an endocrine disruptor and of having toxic effects on the liver, kidneys and lungs at extreme doses, by ingestion. BHT is also suspected of having a potential for bioaccumulation in aquatic species. Lastly, it is wrongly accused of carrying a carcinogenic potential because it is confused with another ingredient called BHA.
Facts
- BHT is not an endocrine disruptor according to the definition by the World Health Organization (WHO), whose role is to direct and coordinate international health within the United Nations.
- Studies showing the potential toxicity of BHT have been performed under conditions that are in no way similar to cosmetic use: ingestion of very high doses. More information here.
- BHT is not considered a bioaccumulative substance for the aquatic environment. It has been evaluated by Sweden in the context of the 2004 European Working Group on Persistence, Bioaccumulability and Toxicity of Products on the Environment
BHT is an antioxidant that prevents the oxidation of products, and in particular the fatty phase of formulas that are likely to rancor or degrade when in contact with the air. It enables to maintain the properties and performance of a product when exposed to air. YSL beauty always uses BHT at an optimal and regulated concentration level: 0.1% in leave-on products and 0.5% in rinse-off products. The safety of its products and ingredients is an absolute priority. YSL beauty only markets products that are safe which have been subject to a very strict evaluation of their quality and safety by internal and third-party experts. As part of YSL beauty’s commitment to continuous improvement, the brand is working with its suppliers to stop the use of BHT as a protecting agent of raw materials.
TETRASODIUM EDTA
Where does it come from?
EDTA is a synthetic ingredient. It is formulated in the laboratory.
What is it used for?
EDTA acts as a chelator. It “grabs” metal ions that can affect the stability and / or appearance of cosmetic products. EDTA is used to counter the hardness of water in rinse-off products. It helps avoid the precipitation of certain ions (calcium, magnesium, etc.) in order to ensure the quality and preservations of products.
Why is it questioned?
EDTA is accused of causing irritation when in contact with the eyes and eczema. There are some concerns regarding the persistence and bioaccumulation in the environment, given the widespread use of EDTA.
Facts
There exists a lot of data on EDTA. Its safe use in cosmetics for decades is well reported. At the concentration level it is used in YSL beauty products, EDTA is a very well tolerated ingredient and allergy cases are very rare.
Why and how does YSL beauty use it?
YSL beauty works with its suppliers to limit the use of EDTA to protect the raw materials used. In a process of continuous improvement, the brand is working to reduce or substitute EDTA present in its formulas when possible, while guaranteeing the same level of quality and product performance.

PARFUM / FRAGRANCE
Where do they come from?
There are two types of ingredients:
- Either obtained by synthesis
- Or extracted from natural ingredients
Why are they used?
The role of smells in social relationships and well-being has been known for millennia. Fragrance ingredients are present in the composition of perfumes, eau de toilette and eau de Cologne. They also contribute to perfuming other cosmetic products (skin care, make-up, hygiene, etc.), where they contribute to the overall performance of the products.
- Well-being
- Products perfuming
Whether natural or synthetic, some perfumes or fragrance ingredients are perceived as causing allergies and others contain substances suspected of being reprotoxic and endocrine disrupting. Others are identified as persistent in the environment.
Facts
- Fragrance ingredients are subject to risk assessment by the IFRA, a body which strictly regulates the use of each fragrance ingredient in each product category. The European Cosmetics Regulation is also involved in the regulation of fragrance ingredients.
- Olfactory compositions are subject to an initial safety assessment by the supplier. They must then meet YSL beauty’s specifications, which may go beyond what is required by international regulations. The brand’s safety assessment takes account of the cumulative effect of fragrance ingredients found in any type of cosmetic product and exposure corresponds to the conditions of use (frequency and area of application). In the case of cosmetic products (excluding eau de toilette), exposure to the fragrance is very low as its content rarely exceeds 1%. This dual evaluation by both the supplier and by the brand’s teams of toxicologists guarantees that the products are used safely, minimizing the risk of allergy.
- Recent studies have included certain fragrance ingredients on lists of potential endocrine disrupters. According to the World Health Organization (WHO) definition of endocrine disrupters, fragrance ingredients are not endocrine disrupters.
HOMOSALATE
Where does it come from?
Homosalate is a synthetic organic compound (based on carbon, oxygen and hydrogen) that absorbs UV rays.
Why is it used?
Homosalate protects the skin from the sun's harmful effects, which can lead to skin cancer in the long-term. Homosalate remains stable and therefore provides effective protection during exposure to the sun.
- Absorbs UV rays
- Anti sunburn
- Stability and effectiveness
Homosalate is suspected of being an endocrine disruptor for humans and aquatic wildlife.
Facts
- Under the European Cosmetics Regulation, the European Commission has identified 28 substances suspected of being endocrine disruptors. The Scientific Committee on Consumer Safety (SCCS) is responsible for examining their possible endocrine activity that is harmful to consumer safety. A first group of 14 substances will be treated as a priority in 2020. Homosalate is part of this first group. According to the World Health Organization (WHO). definition, homosalate is not an endocrine disrupter.
- Available scientific data do not show any endocrine disruption effect of homosalate on aquatic fauna.
YSL beauty uses homosalate in its sunscreen products in combination with all other sunscreens. This sun filter is a very good solvent for other filters, thus limiting the use of other oily compounds and limiting the greasiness and stickiness of products.
Homosalate is authorized worldwide. It is biodegradable, does not bioaccumulate and has no known aquatic toxicity. Its favorable environmental profile is confirmed by the European Chemicals Agency (ECHA).
As with all YSL beauty products, those containing homosalate are systematically subjected to a strict evaluation of their quality and safety for the consumer. This is a fundamental principle that the brand applies throughout the world.
MICA
Where does it come from?
YSL beauty’s mica mainly comes from the USA and India. Mica is extracted directly from the topsoil. It is one of the main compounds of granite.
What is it used for?
Mica is a safe ingredient used in lip make-up, nail polish and foundation thanks to its multiple properties and benefits:
- Sparkle and shine (e.g. in eye shadows)
- Glitter
- Opacity to increase coverage (e.g. in powdered foundation)
In India, mica mainly originates from socially and economically challenged regions where there is a risk of child labor, unsafe working conditions, and where the supply chain involves multiple actors, which makes it difficult to completely assess.
Facts
- Facing these challenges, YSL beauty has committed to remain in India and ensure the traceability and transparency of its supply chain. The brand believes that discontinuing the use of Indian mica would further weaken the situation in the region. In addition, local NGOs and expert organizations are supportive of efforts made to secure the mica supply chain and thus improve the living and working conditions in the region.
- YSL beauty plays an active role in collective actions such as the Responsible Mica Initiative (RMI)* to ensure the responsible sourcing of Indian mica.
- As a signatory of the United Nations Global Compact, YSL beauty is committed to respect and promote human rights throughout its supply chain. This commitment is one of the pillars of the brand’s Code of Ethics.
Why and how does YSL beauty use it?
YSL beauty uses Indian mica for its highly performing properties: bringing shine, glitter or opacity (e.g. for a better coverage in powdered foundation). When technically possible, the brand uses synthetic mica.
Today, 98% of YSL beauty’s mica comes from completely verified sources. The brand is a founding member of the Responsible Mica Initiative and is committed to ending child labour practices and improving the working conditions of Indian communities whose livelihoods depend on mica. By partnering with stakeholders (industries, NGOs, etc.) and mica buyers through the RMI, the brand contributes to ensuring that the sector is responsible, ethical and protects children.
YSL beauty supports the livelihoods of local Indian communities by securing the supply chain. By continuing to source mica in India via a transparent and traceable supply chain, the brand encourages to foster economic development and improve the living conditions of workers in India.
MINERAL OIL / PARRAFIN
Where do they come from?
There are two types: mineral synthetic oils, which are perfectly pure from their production, and mineral oils from petrochemicals. The latter are refined mineral oils that are obtained after the purification of fossil materials such as coal, crude oil or natural gas. The mineral oils used in YSL beauty cosmetic products are of pharmaceutical grade and thus very pure.
What are they used for?
Mineral oils are used in skincare products and lipsticks for their multiple benefits. They protect the skin from dehydration. They are efficient for cleansing and for removing make-up. They improve the quality of textures.
Why are they questioned?
The quality of mineral oils can be put into question due to the possible presence of impurities and polycyclic aromatic compounds that are cancerous. In food, mineral oils (which are saturated fats) can lead to cardiovascular risks. In cosmetics, they are accused of being comedogenic and occlusive (which means they could block the pores of the skin).
From an environmental point of view, mineral oils - which are of fossil origin - are accused of not being assimilated by the environment after usage and that their use contributes to the depletion of natural resources.
Mineral oils are also regularly opposed to vegetable oils which are perceived as more environmentally friendly due to their renewability.
Facts
- Mineral oils have been used in cosmetics for more than 100 years without having ever been associated with intolerance. They are very well tolerated and do not trigger any allergies, which allows them to be used on sensitive and fragile skin types.
- The mineral oils used in YSL beauty products are of pharmaceutical and food grade. Thus, they do not contain polycyclic aromatic compounds.
- As part of its commitment to continuous improvement, the brand strives to keep on reducing the environmental impact of its formulas.
The mineral oils YSL beauty uses are not only duly authorized, they also meet the highest standards in terms of purity, quality and safety. The brand only uses mineral oils of very high quality corresponding to food or pharmaceutical grades. These oils have a very high level of purity and are thus perfectly safe.
Mineral oils used in lipsticks and balms - although the amounts ingested are minimal - are of food grade - the highest level of purity. They are very stable and do not grow rancid. Their properties are complementary to those of vegetable oils. Mineral and vegetable oils each have specificities of their own, responding to different desired effects. They are not substitutable.
ETHYLHEXYL METHOXYCINNAMATE
Where does it come from?
Octinoxate is a synthetic organic compound (based on carbon, oxygen and hydrogen) that absorbs UV rays. It is a derivative of cinnamic acid that can be found in cinnamon.
Why is it used?
Octinoxate protects the skin from the sun's harmful effects, which can lead to long-term skin cancer. This filter mostly absorbs UVB radiation. It has a positive impact on the texture and appearance of the cosmetic products in which it is used.
- Absorbs UVB rays
- Anti-sunburn
Octinoxate is suspected of being an endocrine disruptor for humans and for aquatic fauna. It is also suspected of having an impact on coral bleaching.
Facts
- According to the evaluation by the French Agency for the Safety of Health Products (Afssaps) in April 2012, octinoxate is safe in cosmetic products under authorised conditions, i.e. up to a maximum concentration of 10%.
- According to the World Health Organization (WHO) definition, octinoxate is not an endocrine disruptor. In the absence of a possible conclusion on endocrine disruption effects on aquatic fauna based on the available scientific data, the European authorities have requested that further verifications be carried out.
- Octinoxate has a good environmental profile: it is not toxic to aquatic organisms and is biodegradable.
OCTOCRYLENE
Where does it come from?
Octocrylene is composed of organic compounds (carbon compounds that absorb UV rays) transformed to obtain this sun filter.
What is it used for?
Octocrylene protects the skin from sun damage and premature ageing. It also helps prevent risks of skin cancer. This filter mainly absorbs UVB radiation, and also short UVA radiation, which is responsible for ageing but also for skin cancer. Octocrylene remains stable and thus effective during sun exposure. It enables the use of avobenzone, a sun filter that is particularly effective against UVA rays, by stabilising it. It allows sunscreen products to be water resistant
Why is it questioned?
Octocrylene is questioned due to its allergenic potential. Some cases of allergies by exposure to the sun (photo-allergies) have been identified as well as cases of transient skin irritation in contexts of high concentration of octocrylene. This ingredient is also accused of being an endocrine disruptor.
Facts
- Octocrylene alone does not induce photoallergy. In general, cases of allergies to this ingredient are very rare.
- According to the Scientific Committee for Consumer Safety of the European Commission, octocrylene is not considered a photo-allergen or even an allergen.
- Lastly, octocrylene is not an endocrine disruptor according to the definition by the World Health Organization, whose role is to direct and coordinate international health within the United Nations.
PALM OIL
Where does it come from?
YSL beauty’s palm oil trees are grown in Malaysia and Indonesia, which represents 85% of the world’s palm oil supply. 40% of producers are smallholder farmers. Palm oil comes from the palm fruit while palmist oil is derived from the kernel.
What is it used for?
Palm oil and its derivatives are used for their unique natural cosmetic properties:
- Moisturising
- Foaming, softening and solubilising actions
- Texturising
The palm oil industry often faces criticism for the deforestation it continues to cause and its consequences: clearing of wild animals’ natural habitat (including rainforests), and depletion of valuable carbon sinks including peatlands and trees.
Facts
- 100% of the palm oil sourced by YSL beauty has complied with Roundtable on Sustainable Palm Oil (RSPO) standards since 2010, following the rigorous Segregated (SG) model, one of the most demanding.
- YSL beauty’s ambition and achievements in fighting deforestation have been recognised. In 2017, for the second year running, L’Oréal Group was awarded an “A” score by CDP, the highest possible level of performance. For more information, click here.
Moreover, in 2014, YSL beauty set about tracing its palm oil derivatives back to the field. To date, research has traced 95% of the total palm oil derivatives volume back to the refineries, 85% to the mills and 25% to the plantations. By 2020, at the latest, none of the brand’s products will be linked to deforestation.
YSL beauty is committed to supporting independent smallholders, who make up to 40% of palm oil production, by helping them grow without causing further deforestation. By 2020, the brand’s sustainable sourcing strategy will provide livelihood for more than 10,000 small independent farmers.
PARABENS
Where do they come from?
In cosmetics, parabens are of synthetic origin. Parabens also come from nature and are present in food items such as red fruits, carrots and royal jelly.
What are they used for?
Most hygiene and beauty products contain water, which makes them prone to the growth of harmful pathogens (fungal and bacterial) which could lead to mold, the breakdown of the product and more. Parabens have been used in medicine and cosmetics for close to a century.
- Antifungal and antibacterial properties
- Preventing contamination
- Ensuring the product is safe for consumers
A few non-clinical studies suggested that a certain type of parabens (long chain parabens) might cause endocrine disruption and breast cancer.
Facts
- The most widely used group of preservatives in cosmetics are short-chain parabens. They are safe, gentle, and efficient preservatives.
- These facts are repeatedly confirmed by the EU’s Scientific Committee on Consumer Safety (SCCS°.
YSL beauty is committed to using short-chain parabens only, which are recognized as perfectly safe by the EU’s Scientific Committee on Consumer Safety. Short-chain parabens are well known to be safe preservatives. Short-chain parabens are biodegradable. They do not pose any threat to the environment
PEG/PPG
Where do they come from?
PEG and PPG are synthetic ingredients.
What are they used for?
Mainly used as emulsifiers to homogeneously mix ingredients that are normally immiscible such as water and oils. Also used as thickening or gelling agents. Key ingredients in cosmetic products also used as a food additive in certain food items (E1521).
Why are they questioned?
They are accused of being carcinogenic, of being toxic to the liver and kidneys and of causing allergies. They are also suspected of being toxic for the environment.
Facts
- PEGs present no risk for health. They have been used in the medical field for decades.
- According to the general opinion of scientists and health authorities, PEGs are well tolerated by the skin: they do not present any allergenic potential at their concentration level in YSL beauty products. PEGs can be irritating if used pure but present no risk in formulas when used in low concentrations.
- They are not toxic to the environment, yet they are not biodegradable.
PHENOXYETHANOL
Where does it come from?
In cosmetics, phenoxyethanol is of synthetic origin. Phenoxyethanol can also come from nature and be found in plants such as chicory.
What is it used for?
Phenoxyethanol is used to preserve products from being contaminated:
- It has antifungal properties
- It prevents the contamination of products by microbes
- It boosts the efficacy of other preservatives and decreases the total amount of preservatives needed in a product
Phenoxyethanol is accused of causing endocrine disruption and having effects on the blood and liver at extreme doses. Phenoxyethanol is also said to cause allergies though only very few cases have been observed.
Facts
- The SCCS* from the European Commission reviewed the full data set available and concluded that the use of phenoxyethanol as a preservative at a concentration level of 1% in cosmetic products is safe for all consumer targets.**
- The studies that stirred controversy were conducted under high doses: the equivalent of 120 bottles of cream applied to the skin every day.
- Skin allergies are extremely rare: 1 case out of 1,000,000 users.
**The French National Agency for Medicine and Health Products Safety (ANSM) alone recommended not using phenoxyethanol in wipes or diaper area products. Why and how does YSL beauty use it? YSL beauty uses the optimal concentration of phenoxyethanol, which is below 1%, to ensure its products remain safe and well protected against microbes, so they present no risk for the consumer. As it is the case for all of its products, YSL beauty always assesses their quality and safety profile before they are placed on the market by internal and third-party experts. When present in its products, YSL beauty labels it clearly in the ingredients list on packaging. The brand always informs its consumers in a transparent manner about the ingredients used in its products. Everywhere in the world YSL beauty applies the EU regulations with regards to labelling.
DIMETHICONE
Where do they come from?
Silicones used in cosmetics are of synthetic origin. They are ingredients synthesized from silicon, a mineral compound found abundantly in nature as silica, the main constituent of sand.
What are they used for?
Silicones are used in some cosmetic products thanks to their unique sensory benefits and properties:
- Long lasting effect in lipstick
- Smoothing: they give products like creams or make-up a silky, spreadable, luxurious texture
Silicones are accused of causing skin congestion, clogging pores and dehydrating the skin. Silicones are not easily biodegradable in the environment, meaning some silicones accumulate.
Lastly, the silicone called cyclotetrasiloxane (D4) is suspected of having carcinogenic, mutagenic or toxic effects for reproduction.
Facts
- YSL beauty always chooses silicones that are at once highly performing and with the least impact on the environment. Cyclopentasiloxane (D5) and cyclohexasiloxane (D6) are currently being evaluated at European level under the PBT criteria (Persistent, Bioaccumulative, Toxic) for the environment.
- YSL beauty does not use D4.
SODIUM LAURETH SULPHATE
Where do they come from?
In cosmetics, sulphates are of synthetic origin. Sulphates are ingredients synthesized in the laboratory from fatty alcohol. YSL beauty only uses fatty alcohols of vegetable origin.
What are they used for?
Sulphates are used in cosmetic products such as shower gels, exfoliants, facial cleansing gels, liquid hand soaps, personal hygiene products, toothpastes, thanks to their benefits:
- Cleaning and foaming agent
- Easy to rinse
- Clean sensation
Sulphates are accused of causing irritation or dryness. They are said to remove part of the protective hydrolipidic film naturally present on skin. Sulphates can also sting when in contact with the eyes. Lastly, the supply of fatty-chain alcohols, which are at the origin of sulphates, is questioned as they could be derived from palm oil. The methods of obtaining certain sulphates can lack eco-friendliness.
Facts
- Sulphates, which are destined for use in rinse-off products, do not persist in the environment.
- Because YSL beauty only uses them in products that are rinsed with water, the risk of irritation is very low.
The brand offers products specifically for sensitive skin that are labeled as such. To meet the expectations of certain consumers, it also offers sulphate-free formulas. YSL beauty guarantees a sustainable supply of its sulphates and favor the use of those that have a lower environmental impact. The brand tries to propose formulas that are as biodegradable as possible (> 90%) and also use a selection of softer sulphates, even natural ones.
TALC
Where does it come from?
In cosmetics, talc can be of natural origin and in some cases synthetic. Talc is obtained by powder reduction and purification of magnesium silicate, a naturally occurring crystalline mineral.
What is it used for?
Talc is used in a large number of cosmetic products such as antiperspirants, powdered foundation, feminine hygiene products or baby care, for its multiple properties and benefits:
- For the skin: absorbing properties, transparency, soft and silky finish
- In formulation: for long lasting fragrances, better adherence of textures, efficient to disperse pigments
Talc is accused of being carcinogenic when used in feminine hygiene products, due to the possible presence of asbestos traces in it – which are known to be carcinogenic to humans when inhaled. Talc powder is also accused of causing irritation. Lastly, talc sourcing can be controversial as the revenues coming from talc supplies originating from Pakistan and Afghanistan could contribute to the financing of terrorist groups, due to an opaque and poorly regulated mining.
Facts
YSL beauty does not market feminine hygiene products. The brand only offers two products in the form of talc powder, and all precautions of use are indicated on the packaging so they are used in a safe way by its consumers. Regarding talc sourcing: the talc YSL beauty uses mainly comes from France and Italy, and does not source talc from Afghanistan or Pakistan.
Why and how does YSL beauty use it? The talc YSL beauty uses is of high quality, guaranteeing the absence of risk for bronchopulmonary cancers. As part of its continuous improvement process, the brand has developed a quality commitment with its raw material suppliers to guarantee the absence of asbestos traces in the talc uses.
The precautions of use of talc are clearly indicated on the packaging of YSL beauty products. Because it can cause irritation when inhaled, talcum powder must be used with caution.
YSL beauty’s talc mainly comes from France and Italy. 99,94% of the talc sourced is from secured origin. The brand does not source talc from Afghanistan or Pakistan. Responsible sourcing is at the heart of YSL beauty’s purchasing policy, in line with its values - integrity, respect and transparency. YSL beauty’s teams strive to always improve its control over the talc supply chain.
TITANIUM DIOXIDE
Where does it come from?
In cosmetics, titanium dioxide is used either as a sun filter or as a white pigment. Titanium dioxide is a white powder obtained by transformation of mineral compounds extracted from rocks.
What is it used for?
Titanium dioxide has many applications in food or in cosmetics, especially for:
- Its white coloring properties
- Its ultraviolet filtration properties
Titanium dioxide used as a food additive is currently subject to discussions because of its impact in case of oral exposure (or ingestion) - a different use from that of cosmetics. The controversy around titanium dioxide is linked to the fact that the International Agency for Research on Cancer (IARC) has classified titanium dioxide as a possible carcinogen for humans by inhalation. Titanium dioxide is also suspected of crossing the skin barrier when applied in nanometric form on injured skin. Lastly, there is a debate on the contamination of the environment by titanium dioxide in nanometric form, especially in aquatic ecosystems (plankton).
Facts
- In sunscreens and beauty products, titanium dioxide nanoparticles have been assessed by the Scientific Committee for Consumer Safety (SCCS), which has approved their use as anti-UV, with a maximum concentration of 25%*.
- Whatever its size (nanometric or not), titanium dioxide does not penetrate the skin. More information here and there.
Why and how does YSL beauty use it? When it serves as a sun filter, it is in nanometric form, so it is more efficient. In its other uses, it is used in non-nanometric form. YSL beauty uses titanium dioxide in nanometric form only when it improves the product performance - quality, comfort, texture. When the brand uses titanium dioxide in nanometric form, it is clearly indicated on the product packaging.
YSL beauty only uses nanometric titanium dioxide in products that cannot be inhaled or swallowed, and does not use it in aerosols or lip products. All of the brand’s products undergo a strict evaluation of their quality and safety before they are placed on the market. This is a fundamental principle that YSL beauty applies anywhere in the world.
The type of titanium dioxide used in cosmetics does not impact plankton in the aquatic environment. This type should not be confused with other types of titanium dioxide used in products other than cosmetics.
