I'm a BIG sunscreen user. I'll put it on exposed skin anytime I'll be outside for more than 10 or 15 min., no matter what season or what the weather is like. I used to use "regular" sunscreen (like Coppertone, or the cheaper brand), but switched to Alba Natural sunscreen last year. Over the winter it seemed effective enough. But now that it's summer and the sun is beating down, I've noticed I'm getting a lot tanner than I used to! I'm worried it's not working. I was outside almost all day for 3 days in a row this past weekend. I applied sunscreen generously before going out, and reapplied every 2-3 hours. And STILL, when I got home at the end of the day I noticed tan lines!! UGH! I really want to protect my skin and body from the harmful sun's rays, and would like to do it naturally and safely. But I'm thinking I'll switch back to the other sunscreen b/c at least that worked in keeping the sun from penetrating into my skin. Granted, I know it has parabens, which is why I made the switch. It's like I'm stuck and don't know which is worse......using sunscreen with parabens that blocks the rays, OR using natural sunscreen that still lets rays though. ???? I need help on this one!!
