Science

Mechanism of Action

This ingredient functions as an aesthetic enhancer by forming a protective film on the skin, contributing to a firming and smoothening effect. Rich in amino acids, it supports the skin's natural elasticity and repair processes. With a low molecular weight of approximately 600 Daltons, it readily penetrates the skin's layers, enabling efficient hydration and nutrient delivery to aid in repairing damaged tissues. It also helps to regulate the skin's oil production and fortifies the natural protective barrier, reducing transepidermal water loss and shielding against environmental aggressors, while providing overall dermo-protective action.
