New rules for sunscreens will give consumers much-needed help picking an appropriate sunscreen...starting next summer.
FDA will allow sunscreens to be labeled "broad spectrum" ONLY if they provide adequate protection against both UVA and UVB rays.
This is important.
UVB causes visible sunburn...UVA causes more underlying skin damage. Current SPF ratings apply only to UVB protection.
Sunscreens that contain only UVB protection reduce the obvious signs of burning so people THINK they're protected...but the lack of UVA protection allows damage below the surface.
New products will also no longer claim to be "waterproof" or "sweatproof"...all sunscreens eventually wash off or become less effective when they get wet.
Instead, sunscreens will state if they are "water-RESISTANT" for 40 or 80 minutes. Recommend reapplying sunscreen at least every 2 hours and after swimming or sweating.
For now, tell patients to look for sunscreens that contain ingredients that protect against UVA rays, such as avobenzone, zinc oxide, and/or titanium dioxide.
Limit sunscreen use in infants less than 6 months. Advise applying it to exposed skin only if adequate shade and clothing are not possible...and wash it off afterwards to minimize exposure.
