Non-acid Acid Precursor 15% - 30ml by 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, 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.
A suspension of probiotic bacteria purified through lysis acts as a precursor of skin-compatible natural acids.
Two forms of amino isolates mimic the visible surface-regularizing action of retinoids without any presence of retinoids or related acids.
A bio-ferment oligopeptide offers better exfoliation than alpha acids without irritation or inflammation.
A highly-purified natural levomenol offers surface barrier support, hydration comfort.
A marine-derived exopolysaccharide increases water-retention capacity—essential enhanced skin turnover.
Apply a few drops at bedtime to the face avoiding the immediate eye areas. If used as part of a NIOD regimen, apply after CAIS and MMHC but before HV. If used along with ELAN, apply after ELAN. If sensitivity occurs, reduce application initially to every other night until skin builds tolerance.
