Is Lactic Acid Safe?
Lactic Acid Safety Overview
Official Rating: Mostly Safe (Health Score: 8/10).
pH adjusters (Citric Acid, Sodium Hydroxide, Lactic Acid) are used in trace amounts purely to balance formula pH and do not present safety risks at these levels.
How Lactic Acid Is Used Safely
Lactic Acid is formulated as a ph adjuster for ensuring formula matches the skin's natural acidic mantle (pH 4.5-5.5) in all skincare formulations, especially AHA/BHA exfoliants and vitamin C. Used within approved cosmetic concentrations.
Who Should Exercise Caution?
Generally well tolerated for all skin types, crucial for maintaining a healthy acid mantle. If you have reactive or hypersensitive skin, patch test products before full facial application.
