- Step
- 5 · Treat
- How often
- Up to 2 times a week
- Starting out
- Every second morning for one week, then every morning under SPF. A mild tingle for a minute is normal; stinging that lasts is not, so drop to every third day.
- Ascorbic Acid (23%)High-strength pure vitamin C that brightens skin and targets dark spots, but carries higher irritation potential than derivative forms.
- 3-O-Ethyl Ascorbic AcidA more stable, gentler vitamin C derivative that supports brightening alongside the pure acid.
- GlutathioneAntioxidant that supports skin's defence against environmental stress and works synergistically with vitamin C.
- Sodium HyaluronateHumectant that helps offset the potential dryness of a high-strength acid formula.
