Another stable phosphate ester of vitamin C, chosen by formulators for its water solubility and gentleness compared to pure ascorbic acid. Available safety data and long history of use in leave-on products show a low rate of irritation.

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.
