What Vitamin C does
A powerful antioxidant that brightens dull skin, fades dark spots and boosts your sunscreen's protection against free radicals. Pure L-ascorbic acid works best at a low pH and oxidises (turns orange) quickly.

Frequently asked questions
Can I use Vitamin C and Zinc PCA together?
Yes, it is safe. There is no known chemical conflict between Vitamin C and Zinc PCA, and neither makes the other less effective.
Which goes first, Vitamin C or Zinc PCA?
Apply Vitamin C first, then Zinc PCA. The general rule is thinnest to thickest texture, and lowest pH first.
