lactic acid purpose skincare
Lactic acid is a powerhouse ingredient in skincare that has revolutionized the way we approach gentle yet effective exfoliation. As an alpha-hydroxy acid (AHA) derived from milk, this naturally occurring compound works diligently to dissolve dead skin cells, promote cell turnover, and improve skin texture. In skincare formulations, lactic acid typically ranges from 5% to 12% concentration, making it suitable for various skin types and concerns. Its larger molecular size compared to other AHAs ensures a gentler exfoliation process, making it particularly beneficial for sensitive skin. Beyond its exfoliating properties, lactic acid demonstrates remarkable ability to enhance skin hydration by acting as a humectant, drawing moisture into the skin. The ingredient also helps stimulate collagen production, making it valuable for anti-aging skincare routines. Modern formulations often combine lactic acid with complementary ingredients like hyaluronic acid and ceramides to maximize its benefits while minimizing potential irritation. This versatile ingredient addresses multiple skin concerns simultaneously, from hyperpigmentation and uneven texture to fine lines and dullness, making it a cornerstone of effective skincare regimens.
