What's the best kind? That depends on you. "It's nice to use a product with a higher SPF. But make sure you find a sunscreen that you like because you'll use it more," .
Apply sunscreen 15 to 30 minutes before you go out. Put on enough so that it takes a full minute to rub in. If at the beach, spread at least 1 ounce -- enough to fill a shot glass -- on your face and entire body. Use more if you need to for good coverage. If you swim, sweat, or are outdoors for a long time, reapply every two hours. Your sunscreen should also have the following qualities:
- It is water resistant and sweat proof
- It has SPF of 15 or higher. According to The American Academy of Dermatology, sunscreen-SPF rating is calculated by comparing the amount of time needed to produce a sunburn on sunscreen-protected skin to the amount of time needed to cause a sunburn on unprotected skin.
For example, with an SPF 2 sunscreen a person who normally (without sunscreen) would turn red after 10 minutes of sun exposure would take 20 minutes to turn red. A sunscreen with an SPF of 30 would allow that person to multiply that initial burning time by 30, which means it would take 30 times longer to burn. However, SPF should not be used to determine time in the sun.
Skin damage can happen even without a burn. Plus, higher SPF numbers do not give proportionate protection. SPF 15 deflects 93% of sun-burning rays, whereas SPF 30 deflects 97%, reports the AAD.
- Make sure your sunscreen provides broad-spectrum protection, which is in sunscreens containing benzophenones (oxybenzone), cinnamates (octylmethyl cinnamate and cinoxate), sulisobenzone, salicylates, titanium oxide, zinc oxide, and avobenzone (Parsol 1789).
If the Sunscreen does not have these agents, It may only filter UVB light, the major culprit for sunburn and skin cancer. Yet, protection from UVA is important, too. It is responsible for premature aging and the development of skin cancer.
