The FDA sent warning letters to four companies who claim to make dietary supplements that can protect your skin from sun damage.
The companies are putting people's health at risk, according to the FDA, by giving consumers a false sense of security.
These companies include Sunsafe RX; GliSODin, the maker of Skin Nutrients; Solaricare; and Sunergetic.

One company, Sunsafe RX, says its product is made with items that protect skin from damage, according to clinical studies.
