Vitamin C derivative
Stabilised vitamin C
INCI: 3-O-Ethyl Ascorbic Acid
- What it does
- Vitamin C derivatives were developed to make vitamin C more stable and better absorbed in skincare. In trials, topical vitamin C made skin smoother and measurably lightened pigmentation.
- What it can’t do
- Derivatives differ in how well they work, and the vitamin C trials were small. The ascorbic acid in this formula is listed at 10 ppm (0.001%), so the formula relies on the derivative.
