Science & Benefits
Aminopropyl Ascorbyl Phosphate is an exceptionally stable, water-soluble derivative of Vitamin C. Unlike L-Ascorbic Acid, it does not require a low pH to penetrate, making it far less irritating for sensitive acne-prone barriers. It is zero-comedogenic. Its logic in an acne database is its high efficacy in reducing localized inflammation and fading post-inflammatory erythema (PIE) without the stinging common to acidic Vitamin C formulas.
