About

A vitamin C stereoisomer used to keep formulations from going off — approved as food additive E316, with a long, clean safety record. Acts mainly as a stabiliser rather than a skin-active form of vitamin C.

Function

ANTIOXIDANT

Skin benefits

  • Strong antioxidant — protects formulations from oxidation and rancidity
  • Vitamin C stereoisomer (D-isoascorbic acid sodium salt) — water-soluble and synergistic with other antioxidants
  • Approved as food additive E316 — extensive safety record

Known concerns

  • Less skin-bioactive than L-ascorbic acid — primarily a stabiliser, not a topical anti-ageing active
  • Possible mild irritation in pure form at high concentrations
