Vitamin C Serum: Is It Right for Your Skin?

Vitamin C is a well-known antioxidant that brightens skin and supports collagen production, but concentration and formulation make a big difference in results and irritation.

If you have sensitive skin, start with a lower concentration and use it 2-3 times a week before moving to daily use. Store it away from light and heat, since it oxidizes quickly and loses effectiveness.

Most importantly: vitamin C doesn't replace sunscreen — the two work best together.
