We have always given top priority to ingredients of natural origin and source most of the active principles and ingredients used in our products from the plant world. Mustela Bébé products now contain on average 92% ingredients of natural origin, and up to 99% for some products. However, some ingredients are essential to the preservation, stability and sensory qualities of our products, and for which no alternative exists in nature. Some ingredients of natural origin are not compatible with our high standards of efficiency and safety, or are unpleasant to use. In this case, we use synthetic ingredients assessed by key health authorities and approved by regulatory authorities, which have been proven to be effective and safe for even the most delicate skin. Dermatologically-tested under pediatric supervision, all of our products have a high-tolerance factor and are guaranteed hypoallergenic*. *Formulated to minimize the risk of allergic reaction.
