Sunscreen vs. Sunblock

Many people don’t realize there’s a difference between sunblock and sunscreen. True to its name, sunblock reflects the sun’s rays, thereby blocking them from reaching your skin. Sunscreen, on the other hand, absorbs instead of reflects UVA and UVB lights, the radiation that causes sunburn and skin cancer.

Sunblock often appears white on skin while Sunscreen is “invisible.” To find out if a Sunscreen or Sunblock is effective at protecting skin look for these few ingredients oxybenzone, octyl salicylate, or octyl methoxycinnamate.  There is a catch, though. Sunscreen dries out after a couple hours so you need to reapply frequently.
