About

A stable, gentle vitamin C derivative that provides antioxidant benefits to the skin without the instability issues common to pure ascorbic acid.

Trisodium Ascorbyl Isopalmitate Phosphate is a phosphate-based vitamin C derivative combining ascorbic acid (Vitamin C) with isopalmitic acid and phosphate groups. The phosphate ester linkage makes it significantly more stable than pure L-ascorbic acid while allowing conversion to active Vitamin C in skin. It is approved for cosmetic use in the EU under Regulation 1223/2009 and is recognized for its superior stability compared to direct ascorbic acid formulations, eliminating the need for low-pH formulations that can irritate skin.

  • Brightening and even skin tone
  • Stimulates collagen synthesis
  • More stable than pure Vitamin C

Known concerns

  • Generally very well tolerated
