|---|---|
| Stable derivatives | Resist oxidation |
| Airless opaque packaging | Block light and air |
| Low pH | Preserve ascorbic acid |
FAQ
Q1: Can vitamin C be stable in skincare?
A: Yes. Stable derivatives like sodium ascorbyl phosphate and 3-O-ethyl ascorbic acid resist oxidation better than pure ascorbic acid.
Q2: Why does vitamin C turn brown?
A: Ascorbic acid oxidizes under light, air, and heat, turning brown and losing potency.
Q3: How do I keep vitamin C effective?
A: Choose stable derivatives, airless opaque packaging, and a low pH (below 3.5), and store away from light and heat.
