DocRay:
if you read the article, UVB is not the issue. The issue is the UVA rays, and many subscreens do not contain wither of the above two ingredients. Plus, if they do, studies have shown that the UVA ingredients (except Helioplex or Mexoryl blends) break down UVB ingredients faster than previously thought.
I agree, Zinc/Titanium Oxide is a good UVB blocking ingredient, but it was only until recently that UVA started to become something dermotologists became aware of.
