The FDA requires any sunscreen SPF 15 or lower carry a warning label stating that it only protects against sunburn, not skin cancer or skin aging. It's always a good idea to choose a sunscreen SPF 30 or higher. Our Arizona cancer specialists put together a checklist for choosing your sunscreen. This is why it's a good idea to include other sun safety practices, such as seeking shade, wearing protective clothing, and staying indoors from 10 am to 4 pm when UV rays in Arizona are the strongest.
Apply your sunscreen 20 minutes before going outside. To ensure continued protection reapply every 90 minutes. If you will be actively sweating or in the water, be sure to find a sunscreen that is also water-resistant and reapply each time you get out of the water.
Pay attention to all areas of bare skin, including your neck, face, ears, legs, and tops of your feet. For your lips, choose a lip balm that's at least SPF 15 and reapply it frequently throughout the day.

In many cases, people who get sunburned don't use enough sunscreen, don't reapply it, or use a product that is past its expiration date. Remember, your skin is exposed to UV rays every time you go outside — even on cloudy days, on the snow, and in the water — so practice sun safety by slathering on some broad-spectrum, SPF sunscreen.
They end up getting a lot more UV damage, which, of course, defeats the purpose. For people who have a history or high risk of skin cancer, genetic diseases such as albinism or xeroderma pigmentosum or certain immune disorders, SPF 50 may not be enough. Same goes for certain scenarios, such as hiking or skiing at high altitude or vacationing near the equator.
The Skin Cancer Foundation recommends a water-resistant, broad-spectrum sunscreen with an SPF of 30 or higher for any extended outdoor activity. No single method of sun defense can protect you perfectly.
Sunscreen is just one vital part of a strategy that should also include seeking shade and covering up with clothing, including wide-brimmed hats and UV-blocking sunglasses.
