Lactic acid is a type of alpha hydroxy acid derived from fermented sugars. It works on the surface of the skin to dissolve dead skin cells and encourage renewal. Historically, lactic acid has been used for centuries. Ancient cultures famously used fermented milk baths to soften and brighten the skin, long before modern skincare existed. Today, lactic acid is widely used in professional skincare because it offers effective exfoliation with added hydration benefits.
Unlike stronger AHAs, lactic acid has a larger molecular size. This allows it to penetrate more slowly, making it a gentler option for regular use across many skin types.
Benefits of Lactic Acid for Skin
Lactic acid offers more than surface exfoliation. It gently removes buildup that can make the skin look dull or uneven, revealing smoother texture and improved clarity. At the same time, lactic acid increases ceramide levels, which help the skin retain moisture and feel more comfortable.
With ongoing use, lactic acid for skin supports collagen production, which helps improve firmness and elasticity. These properties make it a popular ingredient in routines focused on hydration, texture refinement, and visible anti ageing support. Lactic acid is often included in exfoliants designed for those who want results without excessive irritation.
Suitability and Skin Types
Lactic acid is suitable for all skin types, including dry and sensitive skin. It is generally considered safe to use during pregnancy and breastfeeding. Always review individual product descriptions and consult with your physician if you have concerns or specific medical considerations.
