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 Mandelic Acid and Vitamin C together?
Yes, but not at the same time. Pure vitamin C is already acidic. Layering Mandelic Acid on top lowers the pH further and raises the risk of stinging and irritation. Use vitamin C in the morning and Mandelic Acid at night.
Which goes first, Mandelic Acid or Vitamin C?
Apply Vitamin C first, then Mandelic Acid. The general rule is thinnest to thickest texture, and lowest pH first. For this pair, though, it is better not to layer them in the same routine at all.
Should I use Mandelic Acid in the morning or at night?
Mandelic Acid: best at night. Use 3–4 nights a week. It is mild enough that many people can use it more often than other acids.
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.
