Beauty Q & A - Sunscreen and Vitamin C

We've moved. Please see the all new Beauty Brains.


Meg's Pondering Sun Protection:
I hear a lot about using vitamin C and antioxidants in addition to a high PPD sunscreen to prevent sun damage and aging. Is there truth to this, or is this just something the cosmetics companies invented?



The Brains Say:
Actually, there is some solid research that indicates antixoidants can have some antiaging properties when used with sunscreens.

We've known for a while that sun protection is one of the best things you can do for your skin. But now,
researchers at the Department of Dermatology, Tulane University School of Medicine, New Orleans LA, have shown that vitamin C and other antioxidants can help with collagen synthesis and a variety of inflammatory dermatoses. In other words - it's really good for your skin!

By the way, kudos to Meg for using the term PPD (Persistent Pigment Darkening), which is one of the proposed methods for measuring sun exposure in humans.
