Interviewer: Not all sunscreens are created equal. Dr. Doug Grossman is a skin cancer expert at Huntsman Cancer Institute. He says if you really want the best protection from cancer causing UV rays, you should use the mineral base type.

Dr. Grossman: And these work as a physical UV blocker. UV rays just bounce off these minerals, and they stay on the skin, so they're very long lasting.

Interviewer: So they're kind of like a mirror?

Dr. Grossman: Yeah, and they block the entire UV spectrum. The other class of products are the chemical sunscreens, and these work by absorbing the highest energy UV rays, so they prevent sunburn, but some of the low energy rays still get through and cause damage.

Interviewer: So next time you're in the store buying sunscreen, look for lotions with zinc oxide, and/or titanium dioxide. They'll be a little bit more expensive, but they'll give you maximum protection.
