A transparent formula
At Mustela, our “secret” recipe is not a secret at all.
All our skin care products are formulated using three carefully selected ingredient families, to ensure efficacy, safety and enjoyment of use at every stage of life.
Our formula, made simple:
• Plant-derived active ingredients, chosen for their proven efficacy on the most delicate skin
• Excipients, for a soft, enjoyable texture and optimal diffusion of active ingredients
• Complementary ingredients to enhance our formulas: a safe and gentle preservation system, pH stabilizers, and in some products, a subtle fragrance for added sensory appeal.
Short, clear, useful formulas and nothing else.
A controlled process at every stage
For formulas that combine quality, safety, and efficacy, we verify these parameters at every stage of product development, conducting over 450 measurements and tests with the involvement of an independent toxicology expert for each product.
Every product undergoes 450 measurements and tests
These assessments and tests include stability testing, product safety testing (including evaluation of antimicrobial protection), in vitro safety testing on reconstructed skin models, and in vivo clinical testing conducted under dermatological supervision. We exclude any ingredient whenever there is any doubt regarding its safety and assess the biodegradability of our cleansing product formulations (in accordance with OECD 302B or 301F methods). Each product must successfully pass all of these tests before being placed on the market.
Independent toxicologist experts at all stages
Their mission? To intervene at all key stages of product development: they evaluate and participate in the approval of each ingredient, they validate the formula and check its safety for babies and expectant mothers, they check and commit to the safety of the finished product before it is placed on the market. No product is marketed without being validated at each of these stages.
Quality and safety monitoring once the product is finished
When the product is launched, we closely monitor its lifecycle—as such we address any complaints and adverse effects with the utmost vigilance as part of our quality and cosmetovigilance process.
