When you’re out enjoying the sunshine, you probably don’t realize what’s going on deep within your skin.

SPF Use: Why Reapplication Matters Most

  People who use a high level of sun protection factor (SPF) tend to spend more time in the sun, but may not reapply their sunscreen as needed.

The study involved 900 Continue reading →

Only 1 in 5 Sunscreens are Safe

In May, the Environmental Working Group (EWG) announced that it had issued its fifth annual guide to sunscreen products and reports that, out of 600 beach and sport sunscreens, only one in five are safe. Sunscreens are meant to protect our skin cells from harmful UVA and UVB radiation. Unfortunately, the jury is still out on exactly what benefit these bottled creams can deliver.
