Official Stockist of The Ordinary

NAAP is a non-acidic alternative to acid-based epidermal resurfacing. Instead of using direct acids like AHA/BHA or retinoids that are common in skincare, NAAP uses fermentation bio-derivatives and amino isolates that act as precursors to skin-compatible acids, encouraging visible radiance and visible surface regularity without the redness and inflammation associated with acids. NAAP was found non-irritating in an independent Human Repeat Insult Patch Test.
