The Antioxidant Add-Ins Worth Looking For
Vitamin C, E, ferulic acid, and friends in SPF.
A classic study found that a topical vitamin C + vitamin E combination provided roughly fourfold protection against UV-induced damage compared with no antioxidant — though it supplements, never replaces, sunscreen.
Antioxidants like vitamins C and E don't filter UV; they mop up the free radicals UV generates, adding a complementary layer of defense on top of sunscreen.
Questions we get a lot
Do antioxidants in sunscreen actually work?
Antioxidants such as vitamins C and E don't filter UV, but they can neutralize some of the free radicals UV generates, adding a complementary layer of defense. They support — never replace — sunscreen. A studied vitamin C+E combination showed measurable added photoprotection.
Which antioxidant add-ins are worth looking for?
The best-studied combination is vitamins C and E, often paired with ferulic acid, which stabilizes them and broadens their protection; niacinamide is another well-supported add-in. Look for them in addition to — not instead of — a broad-spectrum SPF, since antioxidants only complement UV filtering.
Can antioxidants replace my sunscreen?
No. Antioxidants reduce some of the oxidative damage UV causes, but they don't block UV the way filters do. Use them as a bonus layer — for example a vitamin C serum in the morning under a broad-spectrum sunscreen — never as a substitute for SPF.
