FORT MYERS, Fla. UVA and UVB are forms of ultraviolet (UV) radiation. UVB radiation is made up of shortwave rays which affect only the outer layer of the skin,causing sunburns and the more minor skin damage called sun tan. UVA radiation is made up of long-wave rays, which penetrate to deeper levels of the skin.
Both may cause skin cancer. - 2 major types of sunscreens, reflective and absorbing (organic)- 3 scares with sunscreens, hormonal issues, cancer causing and getting into the blood...all without merit...- FDA last year ordered sunscreen manufacturers to make a host of changes by June to sunscreen labels that would better explain how consumers should use the products.- companies were having trouble making the changes, the FDA late extended the deadline to December.
Smaller companies have until December 2013.
The FDA had updated prior rules on sunscreen which dealt only with protection against ultraviolet B radiation but not ultraviolet A rays, which contribute to skin cancer and early skin aging. Sunburn is primarily caused by UVB radiation.
Now sunscreen makers would be required to pass a test by the agency to prove the product protects against both types of rays before labeling sunscreens as providing "Broad Spectrum" protection.
Of those that pass, only sunscreens with a "sun protection factor" or SPF, of 15 or higher can claim to reduce the risk of skin cancer and early skin aging.
Sunscreen products that don't pass the test or have passed but have an SPF between 2 to 14 can only claim to help prevent sunburn.- Under the new rules, manufacturers also cannot call their sunscreens "water proof" or "sweat proof," but only say that they are water or sweat resistant.
Water resistance claims on the product's front label must tell how much time a user can expect to get the declared SPF level of protection while swimming or sweating, based on standard testing.
Two times will be permitted on labels: 40 minutes or 80 minutes.-
Sunscreen makers also cannot claim to provide protection for more than two hours without reapplication or to provide "instant protection" without submitting data to prove that to the FDA
