Consumer Reports - Best UVA and UVB Protection

With the official start of summer upon us, it's time to stock up on sunscreen. To help navigate the vast selection crowding store shelves and to ensure you're getting the best protection against, sunburn and skin cancer, Consumer Reports Health has released its list of top-rated sunscreens.

At an outside lab, they analyzed how well 12 different sprays, lotions and creams blocked both UVA and UVB rays, and tested whether their claimed sun protection factor (SPF) -- the measure of UVB protection -- held up on volunteers who soaked in water while wearing the sunscreen.

Four of those tied for best overall score:

These four -- all sprays -- provided "very good" UVA protection, "excellent" UVB protection, and met their SPF claim even after 80 minutes in the water. Plus, the Up & Up sunscreen was rated a CR Best Buy -- a tag awarded to products that both perform well and come at a reasonable price.

Beyond those four, however, a remarkable number still managed to receive good marks from testing. "This year we have nine that we're recommending and that's a lot," says Gayle Williams, deputy editor for Consumer Reports Health. "Even the one that is last on the list rated good in terms of UVA and UVB protection. So even if you don't buy the one at the top of our list, you're still getting a good product."

Consumer Reports Health also advises the following:

  • Buy sunscreen with an SPF of at least 30 (plenty for most people) that claims to be water resistant (to help keep skin protected while swimming or sweating)
  • For full-body protection, adults should apply 2 to 3 tablespoons of lotion 15 to 30 minutes before going out in the sun. Reapply every two hours or after swimming or sweating.
  • Applying them can be tricky if it's windy so take precautions to make sure you're fully covered.
  • Wear tightly woven clothing and a hat, limit your sun time, and seek shade during the hottest hours of the day.
  • If you buy a sunscreen that has no expiration date, write down the purchase date on the bottle with a permanent marker.
  • Discard your sunscreen at its expiration date or if you've had it for more than two years as it may have lost its potency.
  • Don't make your purchase decisions based on brand alone. Different formulas or SPFs within the same brand may not have equivalent performance

This should be number 1 on everyone's list. A little sun is good for you, but too much can do some serious damage.
