5 Ways to Prevent Skin Cancer


Wear Sunscreen -- Every Day

Sunscreen need not just be for a day at the beach -- it can help provide protection every day. With the ozone layer weakening, there's less natural protection against harmful rays, which makes wearing some form of sun protection even more important. Conveniently, many skin products -- like some moisturizers -- include sunscreen. However, these may have far lower SPFs than dedicated sunscreens.

When choosing a sunscreen, look for one that offers broad-spectrum protection. These sunscreens protect against both UVA and UVB rays. UV rays are invisible, and both types can lead to skin damage, even if they don't result in a visible burn.

Choose something SPF 15 or higher, and keep in mind that the California Department of Public Health warns that some SPF numbers are overstated. For that reason, it may be best to err on the side of caution by choosing a sunscreen with a high SPF [source: California Department of Public Health].

If you have sensitive skin, look for a sunscreen that's PABA-free. Reapply every few hours, even if the product label claims it lasts longer. It's also important to reapply if you've been in the water or become sweaty.
