Sunscreen, How High Should You Go?

15, 30, 45, 50 and 100 SPF! What do the numbers mean and which one is right for you this summer? Triple digit sunscreen protection may sound like a good idea but the high numbers can be misleading. Stratospheric SPFs provide only slightly higher sun protection than a 30 SPF that is suitable for most sun-goers.

For the most part, the high numbers are a marketing race to the top of the sunscreen industry. The best advice is to apply thoroughly 30 minutes before heading outside and reapply every two hours or after swimming or sweating.
