BUTTERMILK EXTRACT POWDER.

Valuable / ANTIOXIDANT, EMULSION STABILISING, HAIR CONDITIONING, HUMECTANT, SKIN CONDITIONING, SKIN CONDITIONING - EMOLLIENT

A bioactive powder derived from buttermilk that delivers sphingolipids, lactic acid, and milk proteins to strengthen skin barrier function and provide gentle conditioning. This multifunctional ingredient combines the exfoliating benefits of natural alpha-hydroxy acids with barrier-replenishing phospholipids and ceramide precursors. Clinical research demonstrates its ability to enhance filaggrin expression and maintain hyaluronic acid synthesis while offering protection against photoaging.

Science

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.
