Cyclopentasiloxane is used in Stelatopia balm and emollient cream products to ensure their effectiveness and rapid relief of babies and children with atopic skin. This ingredient is sometimes questioned because it can contain, under certain conditions of manufacture, traces of cyclotetrasiloxane, an ingredient with harmful effects for men and the environment. Mustela guarantees the use of cyclopentasiloxane of controlled quality. Dans les conditions testées, le cyclopentasiloxane et les produits qui en contiennent n'induisent pas d'effet perturbateur endocrinien.
Nanoparticles are ultra-fine particles (about 100,000 times smaller than the thickness of a hair). They are defined by the cosmetic regulations *. We have chosen not to use them in our products. * defined in the cosmetic regulation 1223/2009 / CE explained by the professional recommendation of the European Association of Cosmetic Industries.
No, we do not have carcinogenic substance in Mustela products. There is a classification of ingredients that carry a carcinogenic risk established under the control of the health authorities and Mustela prohibits the use of these ingredients in all its products.
To ensure maximum safety, efficiency and pleasure of use, we use synthetic ingredients that have no natural equivalent as safe and effective.
Preservatives play a vital role in cosmetic products: they prevent all microbial growth.Specifically, cosmetic products for babies are usually used in bathrooms and this warm, damp environment encourages bacterial and fungal growth. If they contaminate the skincare product, these germs could cause severe infection in the user, especially if that user is a baby. Mustela selects its preservatives carefully to ensure they are effective and well-tolerated.
No, we don't use this ingredient in our products.
Non opened, Mustela products are most effective between 24 and 36 months from their date of manufacture. After the opening we advise you to use our products before the expiration date shown on each product's packaging by this logo (period-after-opening labelling) (see the pictogram) To ensure that your Mustela skin care products last we recommend that you close them properly after use and not to transfer them to any other container
The conservation system we use for our products takes into account the combination of ingredients that creates an unfavorable environment for microbial growth (e.g. glycerin, sugar derivatives, citric acid, antioxidants) and a choice of packaging that limits the product's contact with ambient air while preventing contamination (e.g. airless packaging). The preservatives paraben, phenoxyethanol, triclosan or MIT/MCIT are not used in any Mustela formulas. Before it comes on the market, the product is tested to make sure there is no contamination and that it conserves properly without losing its properties. The safety of Mustela products has been our top priority for over 65 years. For more information, go to the "Proven safety and efficacy" section in "Our Commitments". Pour toute information complémentaires, nous vous invitons à consulter la rubrique "Une sécurité et une efficacité démontrées" dans "Nos engagements".
PEG (or PolyEthylene Glycol) is used to ensure the stability of the formula. They are sometimes questioned because they can contain harmful impurities and in particular 1-4 dioxane, if its manufacture is poorly mastered. Mustela selects PEGs whose purity, evaluated by dosing up to the trace level (less than 1 ppm), guarantees a safe use. Despite the security of the PEGs we use, we are committed to removing them from our formulas whenever possible to reassure parents.
In order to guarantee optimum safety for users, cosmetic products have been rigorously governed for over 40 years by specific regulation that applies to the entire European Union. It is regularly updated to take account of scientific and technological advances. This regulation notably defines the lists of banned substances (of which there are over 1300), restricted substances, and the steps that must be taken before a product can be marketed. It also provides a framework for guaranteeing product safety, and defines the responsibilities of manufacturers.Once the cosmetic products are on the market, they are monitored the entire time they are available in order to ensure they are tolerated. Cosmetovigilance is the collection and analysis of any adverse effects that are observed. Mustela is regularly subjected to these checks, and works closely with the authorities each time one is required. Outside of Europe, other countries have their own specific regulations pertaining to cosmetic products (safety, marketing, product monitoring).
