When it comes to keeping your heart healthy, what foods you eat and the genes you inherit matter. Good heart health also may depend on the drugs you take. Several medicines are effective at lowering blood cholesterol levels—a key factor in good heart health. Chief among them are the statins.
Statins (HMG-CoA reductase inhibitors) are one class of many drugs used to lower the level of cholesterol in the blood by reducing the production of cholesterol by the liver. Statins block the enzyme in the...
final regulations that establish standards for testing the effectiveness of sunscreen products and require labeling that accurately reflects test results
a proposed regulation that would limit the maximum SPF value on sunscreen labeling to “SPF 50+”
a data request for safety and effectiveness information for sunscreen products formulated in certain dosage forms (e.g., sprays)
a draft guidance for sunscreen manufacturers on how to test and label their products in light of these new measures.
These measures are necessary, says Lydia Velazquez, PharmD, in FDA’s Division of Nonprescription Regulation Development, because “our scientific understanding has grown. We want consumers to understand that not all sunscreens are created equal.”
“This new information will help consumers know which products offer the best protection from the harmful rays of the sun,” Velazquez says. “It is important for consumers to read the entire label, both front and back, in order to choose the appropriate sunscreen for their needs.”
Everyone is potentially susceptible to sunburn and the other detrimental effects of exposure to UV radiation.
FDA's Final Regulations
The final regulations, which become effective in one year, establish a standard test for over-the-counter (sold without a prescription) sunscreen products that will determine which products are allowed to be labeled as “Broad Spectrum.”
Products that pass this test will provide protection against both ultraviolet B radiation (UVB) and ultraviolet A radiation (UVA). Sunburn is primarily caused by UVB. Both UVB and UVA can cause sunburn, skin cancer, and premature skin aging. A certain percentage of a broad spectrum product’s total protection is against UVA.
Under the new regulations, sunscreen products that protect against all types of sun-induced skin damage will be labeled "Broad Spectrum" and “SPF 15” (or higher) on the front.
The new labeling will also tell consumers on the back of the product that sunscreens labeled as both “Broad Spectrum” and “SPF 15” (or higher) not only protect against sunburn, but, if used as directed with other sun protection measures, can reduce the risk of skin cancer and early skin aging. For these broad spectrum products, higher SPF (Sun Protection Factor) values also indicate higher levels of overall protection.
By contrast, any sunscreen not labeled as “Broad Spectrum” or that has an SPF value between 2 and 14, has only been shown to help prevent sunburn.
Reynold Tan, a scientist in FDA’s Division of Nonprescription Regulation Development, notes that FDA has been developing testing and labeling requirements for sunscreen products for decades. However, only recently have the data become sufficient to establish an accurate and reliable test for broad spectrum UV protection, he says.
