Science

Mechanism of Action

This polypeptide, sourced from milk whey, delivers a spectrum of amino acids that function as Natural Moisturizing Factors (NMFs), drawing and retaining water to boost hydration, volume, and resilience. It actively promotes skin cell regeneration and strengthens the epidermal barrier, creating a protective shield against environmental aggressors. Key components like lactoferrin exhibit antimicrobial, antifungal, and antiviral properties, beneficial for conditions such as acne and psoriasis, while glycomacropeptide reinforces the lipid barrier and offers prebiotic effects. Furthermore, it aids in improving the stability of other ingredients and enhancing the penetration of active substances into deeper layers of the skin.
