Summer is around the corner, which means it's time to check your supply of sunscreen. As you probably know, UV light comes in several flavors, none of which are very good for you, but UVB is the one that can directly damage your DNA, which can lead to skin cancer. Remember, UV"B" is for Bad.
Most sunscreen contains oxybenzone, an organic chemical which absorbs UVA and UVB radiation. One study found that it can also penetrate the skin where it promotes the production of free radicals when exposed to light. This led some consumer groups to release lists and lists of sunscreens that contain or don't contain nanoparticles.
Consumer Reports tests sunscreens for their efficacy in preventing sunburn and found several which are effective.
One that seems to be okay: Neutrogena Sensitive Skin Sunblock Lotion, SPF 30. (Effective against sunburn, no oxybenzone)
One to avoid: Coppertone Dry Oil Continuous Spray Sunscreen, SPF 15. (Oxybenzone, nano particles, and does not protect well against sunburn.)
