The Luminosity Active
Vitamin C
The most studied antioxidant in skincare — the source of true radiance.
What it is
In plain language
Vitamin C (ascorbic acid and its stable derivatives) is the most clinically studied antioxidant in skincare. It defends skin against environmental stress, brightens tone, and supports the synthesis of collagen.
The science
How it actually works
Ascorbic acid neutralises free radicals generated by UV and pollution, donating electrons to stabilise reactive species. It is a co-factor required for the enzymes prolyl- and lysyl-hydroxylase, which are essential for collagen cross-linking. It also inhibits tyrosinase, helping to fade pigmentation.

Your questions, answered
