The FDA will no longer allow sunscreens to claim specific SPFs over 30...sunscreens that actually provide higher protection will be labeled "30+."

There's no official rating system yet for UVA protection. UVA rays are less likely to burn...but they contribute to skin damage and can trigger photosensitivity reactions.
