First of all, if your skin is acne prone, you'll want to use a special sunscreen designed just for your face and another for the rest of your body. Go for an oil-free face lotion like the one shown that is specifically formulated not to clog your pores — the technical terms is noncomedogenic. If your body is prone to breakouts, choose an
oil-free body sunscreen that's also noncomedogenic.
If you have acne lotion or topical medication you use, apply it to your clean skin first, and then apply the sunscreen 30 minutes before heading out into the sun. As soon as you come inside wash the sunscreen off. If you've tried a certain brand of sunscreen, and it's caused pimples then try another one. It may take a few tries or a visit to your dermatologist for suggestions, but whatever you do, don't give up and forget the sunscreen. Your skin will thank you later.
