Don't forget to use good sunscreen:
The US Food and Drug Administration—which regulates sunscreens in this country—has now issued a new set of rules on how products promoted as sunscreens can be advertised. The effective date of these new rules was December of 2012.
Some tips on selecting a good sunscreen:
· Look for the statement “broad spectrum.” Broad spectrum means the sunscreen protects against the worst ultraviolet rays—which are called UVB rays—but also UVA rays—which have been implicated in wrinkling and also contribute to skin cancer. (Older sunscreens didn’t have much UVA protection.)
· Look at the SPF on the label, which stands for Sun Protection Factor. This number measures the length of time one can be in the sun before developing a sunburn with the sunscreen on, compared to how long one could be in the sun with no sunscreen before a burn occurs. So SPF 10 would imply that one could be in the sun 10 times longer when using that sunscreen.
· Note that the SPF number is misleading since it implies you’ve used the required amount of sunscreen. Even an SPF 150 sunscreen is not worth much if you’ve sweated it all of!
· The statement “waterproof” is now prohibited on sunscreens. “Water resistant” is allowed but it only measures ability to protect from a burn after either 40 or 80 minutes in a pool. So reapply that sunscreen every two hours! And you can look for cream, gel, spray, or aerosol forms of sunscreen.
· The FDA is still studying whether to restrict claims of SPFs over 50 (such products are more expensive without much additional protection). Keep tuned for further developments.
