Dermatologists are advising people to use sunblocks instead of sunscreens to prevent damage from harmful UVA and UVB rays. Zinka sunblock is great because it has zinc oxide that blocks the sun. It goes on smoothly, and even the colorful versions can be blended into your skin. I use it when I'm going out on the water. It's waterproof, so it stays on when most other sunscreens dissolve away.
