After researching about sunscreen, I found that SPF is not an indicator for strength but chemical that contains. Zinc and Titanium are the most effective for preventing sun damages. I looked for a sunscreen with Zinc, since Titanium wouldn't work for broader range of UV.
Neurtrogena Ultra Sheer had been my favorite because of dry feel, until I learned that the strength of protection from Helloplex is very weak. Now I know why I keep getting bad sun spots after being out side for hours. I needed reliable sunscreen since I started using at-home chemical peel. I bought this Pure & Free liquid daily sunblock and Coppertone Sensitive Skin Faces 50 SPF, that has twice more Zinc and water proof, so that I could compare. Pure & Free liquid daily sunblock has light feel but grainy, while Coppertone feels ticker and heavy. After a couple of hours, though, both leaves same feel on skin. Both works fine when applying under makeup.
