A Method of Measuring Ultraviolet A (UVA) Protection in Sunscreen Products
Posted Jun 06 2010 5:00pm
Description of Invention: There are different types of ultraviolet (UV) rays in sunlight. UVB radiation causes redness (erythema) or sunburn. While UVA radiation, which absorbs deep into the skin, causes more long-term effects such as wrinkles, skin aging and skin cancer.
Effective sunscreens are expected to block both UVA and UVB radiation. The Sun Protection Factor (SPF) label found on all over-the-counter sunscreen products is a better measure for UVB protection than UVA protection. Currently, there is no standard in vivo test to determine the amount of UVA protection in sunscreen products, despite the fact that many products are advertised as effectively blocking both UVA and UVB radiation.
This invention describes sets of genes useful for measuring UVA exposure in human skin and assessing sunscreen products for their ability to block UVA radiation.
Applications: A test for measuring UVA protection provided by sunscreens.
