Mexoryl just received FDA approval in the US. Will be sold under the name anthelios I believe. Excellent at stopping those naughty UVA rays. (UVB think UV 'burn'---SPF stops it and it causes sunburns and skin cancer. UVA think UV 'age'---causes tanning then gives you wrinkles and brown spots later). Topical antioxidants such as Coenzyme Q10, vitamin C, Prevage, also help reduce oxidative stress after sun exposure. Recent evidence suggesting that Vitamin D may have anti-solid tumor effects including against Melanoma. USRDA (200 I.U.) may not be sufficient---some are suggesting as high as 1000 I.U. may be more like it in adults. Skin that is constantly exposed to sun (like your face) loses the ability to make Vitamin D, so ingesting it is still helpful for most of us. Ant--sounds like you may have rosacea.

. Final rant per the topics raised in this discussion thread: there are a couple of "suspect" genes, that, if present, may greatly increase one's risk for Melanoma---especially one called p13. Still in it's infancy as far as testing is concerned, too many false positives and false negatives.
