Science
Mechanism of Action
This ingredient primarily acts as a biomimetic skin conditioner, supplying vital exogenous lipids that integrate into the epidermal structure. By precisely filling micro-gaps within the intercorneocyte clusters, it effectively reconstructs and strengthens the skin barrier. This action not only optimizes cellular hydration but also provides a protective shield against external stressors and inflammation. Furthermore, it forms a surface occlusive layer to meticulously prevent transepidermal water loss (TEWL) and bolsters the lipid content in the superficial layers, guarding against dryness and lipid depletion.
