Science

Mechanism of Action

This advanced derivative of hydrolyzed milk protein operates by stimulating intrinsic skin repair mechanisms, promoting the synthesis of collagen critical for maintaining skin elasticity and diminishing the appearance of fine lines. Functioning as a humectant, it forms a protective film on the skin's surface, effectively preventing moisture loss and ensuring optimal hydration, resulting in a smoother, more even complexion. The ingredient's rich composition of peptides, amino acids (such as cysteine and methionine), and Vitamin B6 contributes to its ability to regulate sebum, nourish the skin, and fortify the skin barrier. It also supports cellular restructuring and can act as a gentle cleanser by binding to impurities and dead skin cells.
