Check out the FDA page: Sunscreen: How to Help Protect Your Skin from the Sun- Drug Information Update

The Division of Drug Information (DDI)- serving the public by providing information on human drug products and drug product regulation by FDA.

As an FDA-regulated product, sunscreens must pass certain tests before they are sold.  But how you use this product, and what other protective measures you take, make a difference in how well you are able to protect yourself and your family from sunburn, skin cancer, early skin aging and other risks of overexposure to the sun. Some key sun safety tips include:

• Limit time in the sun, especially between the hours of 10 a.m. and 2 p.m., when the sun’s rays are most intense.
• Wear clothing to cover skin exposed to the sun, such as long-sleeved shirts, pants, sunglasses, and broad-brimmed hats.
• Use broad spectrum sunscreens with SPF values of 15 or higher regularly and as directed.
• Reapply sunscreen at least every two hours, and more often if you're sweating or jumping in and out of the water.
