Science
Mechanism of Action
Dried buttermilk operates primarily through its lactic acid content, a natural alpha hydroxy acid (AHA) that gently facilitates exfoliation by dissolving dead skin cells and promoting cellular renewal. Its rich profile of milk proteins deeply nourishes and softens the skin, enhancing elasticity and providing significant moisturization. Furthermore, it exhibits astringent properties that contribute to skin firming and tightening, visibly minimizing pore appearance. The ingredient is also fortified with vitamins (A, D, B2, B12) and minerals (potassium, calcium) crucial for supporting healthy cell turnover, tissue regeneration, and maintaining optimal skin hydration levels.
