Is Potassium Hydroxide Safe?
Potassium Hydroxide Safety Overview
Official Rating: Safe (Health Score: 6/10).
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 Potassium Hydroxide Is Used Safely
Potassium Hydroxide 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.
