Science
Mechanism of Action
Functions through multiple pathways including mild enzymatic exfoliation via lactic acid content, lipid barrier restoration through milk sphingolipids and glucocerebrosides that stimulate endogenous ceramide production, and skin conditioning via film-forming proteins that enhance moisture retention and aquaporin-3 expression.

Key findings
- 01 1% concentration significantly improved skin barrier recovery and increased filaggrin and aquaporin-3 expression while maintaining hyaluronic acid levels (MDPI, 2020)
- 02 Buttermilk concentrated powder suppressed UVB-induced oxidative stress and inhibited collagen-degrading enzymes while stimulating procollagen type I synthesis (PMC/NIH, 2022)
