Can vitamin-based skincare products help my spf work better?

Topical Vitamin C: The antioxidant and anti-inflammatory properties of vitamin c (l-ascorbic acid) help protect the skin from damage caused by uv light. The added levels of l-ascorbic acid achieved by topical application provide photoprotection to the skin. This “photoprotective” effect makes topical vitamin c a very useful adjunct to sunscreens (not a replacement) in reducing sun damage and subsequent photoaging.

Yes: While sunscreens help block the damaging rays of the sun, topical antioxidants like vitamin c will actually repair some of the cellular damage cause by sun exposure.
