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 Azelaic Acid and Vitamin C together?
Yes, it is safe. There is no known chemical conflict between Azelaic Acid and Vitamin C, and neither makes the other less effective. They share a goal (pigmentation), so together they reinforce each other.
Which goes first, Azelaic Acid or Vitamin C?
Apply Vitamin C first, then Azelaic Acid. The general rule is thinnest to thickest texture, and lowest pH first.
Should I use Azelaic Acid in the morning or at night?
Azelaic Acid: works morning or night. Apply once or twice daily. A mild tingle in the first week is normal.
Should I use Vitamin C in the morning or at night?
Vitamin C: best in the morning. Apply in the morning on clean skin before moisturiser and sunscreen. Store it away from light and heat, and throw it out once it turns dark orange.
