Lactic Acid (CAS 50-21-5) is one of the most versatile AHAs in modern skincare. Unlike harsher acids, it combines gentle exfoliation with humectant moisturizing — smoothing the skin while attracting and binding moisture. That dual action makes it a go-to active for sensitive, dry and mature skin formulas.

Key Applications in Personal Care

• Daily AHA serums and lotions: low-strength lactic acid (2%–5%) supports regular, gentle cell turnover for smoother texture.
• Moisturizing & smoothing creams: pairs exfoliation with hydration, ideal for dry and flaky skin.
• Body care: helps refine rough skin and keratosis pilaris on arms and legs.
• Anti-aging & skin-renewal products: supports a brighter, more even complexion over time.
• pH adjustment: serves as an effective acidulant to optimize formula pH.

Why Formulators Choose It

Lactic acid is generally better tolerated than glycolic acid at comparable use levels, which broadens its application window — from leave-on daily care to professional peels. Its natural, fermentation-derived profile also fits clean-beauty positioning.
