About half of US adults suffer from sunburn each year, and nearly 2/3 of all children. More than 30,000 visits to EDs and UCs every year for sunburn injuries. As much as we fear sunburn, 47% of the US population are unlikely to protect themselves from sun exposure. Erythema from sunburn is usually observable 3-5h after UVB exposure, peaks as 12-24h, and fades over 72h--leads to vasodilation of superficial blood vessels and increased vascular permeability, and edema.

Isn't it true the FDA will no longer allow sunscreens to say they're waterproof, too?

Mike W., MD -

From Rick:
Yup!
The 2001 rules also do away with "waterproof" and "sweatproof" labels on sunscreens, because such claims are impossible. Instead, the products can list sweat resistance up to 80 minutes.
Thx for your comments!!
