Commonly Used In: Leave-on exfoliating serums and toners Hydrating peels and overnight treatments Brightening creams and masks pH adjuster in emulsions Foot and body exfoliants Why Choose Lactic Acid? Lactic Acid is a mild, naturally occurring AHA that not only exfoliates dead skin cells but also attracts moisture, making it ideal for dry or dull skin. It promotes cell turnover, smooths rough texture, and brightens skin tone with minimal irritation. It is often used as a gentle alternative to glycolic acid and is suitable for all skin types when used within safe concentration and pH limits. Key Benefits: Exfoliates and improves skin texture Hydrates and supports skin’s natural moisture factor (NMF) Brightens uneven skin tone Less irritating than other AHAs, ideal for sensitive skin Can also be used as a pH adjuster in formulations Usage Guidelines: Cosmetic leave-on products: Use up to 10% lactic acid with a final pH ≥ 3.5 Professional/reserved use only: Above 10% concentration or pH below 3.5 Formulations should always be patch tested for irritation risk Use in combination with SPF in daily skincare routines Avoid use in eye-area or lip formulations Labeling Requirements: Include warning when lactic acid is used at levels >3%: "This product contains an alpha hydroxy acid (AHA) that may increase your skin’s sensitivity to the sun and the possibility of sunburn.
