Best Vitamin C Facial Serums

Vitamin C serums that brighten and protect

Vitamin C is one of the most studied antioxidants in skincare. Applied in the morning, it neutralizes free radicals from UV and pollution, supports collagen, and gradually fades dullness and uneven tone. Concentration and formulation matter, which is why professional serums tend to outperform drugstore versions.

Editor's picks

SkinCeuticals C E Ferulic is the benchmark 15% L-ascorbic acid serum for normal to dry skin. Phloretin CF suits combination skin, and Obagi Professional-C Serum comes in 10% and 15% strengths for different tolerances. SkinBetter Alto Defense Serum pairs vitamin C with a broad antioxidant blend for sensitive skin.

How to use vitamin C

Apply a few drops to clean, dry skin each morning before moisturizer and sunscreen. Store it away from light and heat, and replace it if it turns deep amber. Vitamin C and daily SPF work best as a pair.
