10 Facts To Help You Prepare For Summer's Sunniest Days
- Sunblock- Completely BLOCKS the suns rays. Sunblocks utilize titanium oxide or zinc oxide as the active ingredient, which results in a thicker, opaque consistency.
- Sunscreen- Filters or screens the sun's UV rays -- keeping most rays out, but letting some in. (FYI: Sunscreens use a variety of chemicals that work to absorb harmful UV rays before they penetrate your skin. Sensitive skin people beware: Think, PABA. Brands now blend the two, so make sure you read the bottle.)
- UVA rays can prematurely age your skin, causing wrinkles and age spots, and can pass through window glass.
- UVB rays are the primary cause of sunburn and are blocked by window glass.
- Water-resistant: The FDA considers a product "water-resistant" if it maintains its SPF level after 40 minutes of water exposure.
- Waterproof: A product is considered "waterproof" if it maintains its SPF level following 80 minutes of exposure to water. If you participate in outdoor recreational activities including swimming, you may want to choose a waterproof sunscreen.
