What are the different types of sunscreen?

Dr. Michael Roizen, MD
Internal Medicine
Different sunscreens use different chemicals for blocking out rays. Some use paraminobenzoic acid (PABA) and others use benzophenones or Parasol 1789. Each composition is better than the others at blocking out a particular type of UV ray. Studies on albino rats show that mixing all three provides the best overall protection. Consider using two or three different sunscreens at once, a PABA-based one, a benzophenone-based one, and a Parasol 1789-based one. (There must be a sunscreen that has all three, I just have not found it yet.) If you are going to be out a long time, you should also use zinc oxide on areas particularly vulnerable to skin cancers, like the lips and nose. If you are planning on exercising or being in the water, make sure to apply water-resistant products or, better yet, waterproof products.
