Water-based vitamin C at a tolerable 8%, paired with alpha arbutin for pigmentation. Gentler than pure 20% L-ascorbic acid suspensions — a sensible first vitamin C for most skin types. Expect a mild tingle; discontinue if it stings.

What's actually doing the work
Vitamin C
L-Ascorbic Acid / Ascorbyl Glucoside / MAP / THDA
Vitamin
The gold-standard antioxidant for skin. L-Ascorbic Acid neutralises free radicals, inhibits tyrosinase to fade hyperpigmentation, is essential for collagen biosynthesis, and provides measurable photoprotection under SPF. Derivatives like Ascorbyl Glucoside and Tetrahexyldecyl Ascorbate are more stable and gentler. Results visible in 4–12 weeks.
