Mandelic Acid

Mandelic acid is a larger-molecule alpha hydroxy acid that tends to penetrate skin more slowly than glycolic acid, which is generally associated with less stinging and redness. It carries the same general AHA cautions around sun sensitivity but is often better tolerated by reactive skin.

Cosmetic information for general education, not medical advice. A verdict is a reading of the published evidence, never a guarantee for your skin: any ingredient can irritate someone, so patch test new products and see a professional if you react. Concern is graded on cited evidence, never on hazard-score lists. See how we score.
