The FDA this week released suggested changes in the labeling and testing of sunscreen products, which regulates all sunscreen products in the United States.
The revised monograph would also specifically outline how manufacturers can test for the sun protection factor (SPF), as well as the ultraviolet A (UVA) protection factors offered by sunscreens.
This monograph lists the active sunscreen ingredients like ultraviolet filters that are permitted for use in the United States, the chemicals used, their concentration, and combinations of sun-protective chemicals.
The FDA will now specify how manufacturers can test for SPF as well as the UVA protection factors offered by sunscreens.
In addition, the FDA proposed to increase the cap of ultraviolet B (UVB) SPF to 50+.d. It has also proposed a four-star UVA protection rating system based on in vivo and in vitro testing methods.
