If you're planning on swimming and sweating in the Summer sun, then you need to make sure your sunscreen that is up to the task of protecting you in those harsh conditions. I think I have found the ultimate sunscreen for the job. Hawaiian Island Creation SPF 50 Sunscreen ($11.99) is waterproof, sweatproof, and kept me from burning during my very sunny, very hot first sprint distance triathlon. Created by a biochemist who just happens to be an avid surfer, this sunscreen stays put in adverse conditions – it won't run into your eyes.
Virtually odorless, HIC sunscreen protects against both UVA and UVB rays. It also doesn't feel greasy and won't affect your grip or make you slip. It is, however, not considered noncomedogenic. But a clogged pore is fleeting and a wrinkle is forever.
Pick up some HIC at DrugStore.com before you head to the beach.
