The FDA hopes drugstores will soon be serving up 4 star sunscreen.
In a move to help consumers select a wide spectrum sunscreen, the FDA has proposed a star ranking system to indicate how effective a sun protection product is at blocking UVA rays. The SPF ratings are only for UVB rays, the sun rays that tend to burn your skin, but UVA rays, considered the tanning rays, are just as dangerous to your skin.
If the FDA proposal becomes final, sunscreen products would list both the SPF alongside a new four-star rating system, with one star representing the lowest protection and four stars the highest. Additionally, if the sunscreen leaves you completely defenseless against the sun's UVA rays, the label will explicitly state "no UVA protection" on the front label of the product.
We could start seeing the four star system as early as next spring.
