EWG has evaluated hundreds of sunscreens based on the protection they provide from the sun and the toxic chemicals they contain. The top-rated sunscreens provide broad-spectrum (UVA and UVB) sunburn protection with fewer hazardous chemicals that penetrate the skin. These sunscreens are mineral based with zinc or titanium as the active component.
Broad spectrum protection is important because while all sunscreens provide protection from UVB rays not all sunscreens protect from UVA rays. In the past, it was thought that only UVB rays caused sunburn and skin damage however scientists have now realized that UVA rays are also harmful and the need for a full spectrum sunscreen has emerged.
A non-toxic sunscreen is also important to look for since sunscreen will penetrate the skin and be absorbed into the body. Many sunscreens contain the notorious hormone disruptors oxybenzone or 4-MBC. Oxybenzone has also been know to trigger allergic reactions.
