3 Things You Didn't Know About Sunscreen

It's that time of year -- out comes the sun and out comes the sunscreen. Many sunscreens, however, don't quite deliver, so here are three important things to remember.
  1. Avoid the spray-on varieties. You are not inhaling anything and they don't cover up completely.
  2. Don't trust an SPF over 50. SPF's sun protection ability tops out between 30 and 50.
  3. Stay away from common ingredients like retinyl palmitate and oxybenzone. Kids should especially avoid retinyl palmitate, which can lead to skin lesions and cancer. Oxybenzone can affect hormone levels in our bodies.

A little homework and you'll have a safe day at the beach!
