the Difference Between a Sunscreen and a SunblockSunscreens are the most popular at the moment. Available in creams, lotions and gels, they contain chemicals that absorb UV rays. They are also inconspicous on the skin. The chemicals that are most often found in sunscreens include PABA, Benzophenones, Cinnamates, Salicylates,
Sunblocks instead of absorbing UV rays, reflect them. At one time sunblocks could be spotted by the opaque white film, but new technology has created sunblocks with particles so tiny, that the opaque film in no longer noticeable. Chemicals most common in sunblocks include Titanium dioxide and zinc oxide.
Choose the Best Sunscreenf you have ever been to the tanning/sunscreen aisle at your local drugstore, you know how overwhelming it can be. SPF this, UVA that, and then throw in UVBs in the mix and the confusion begins!
Choosing the Right SPFSPF stands for Sun Protection Factor. The higher the SPF number, the better protection against the sun's harmful UVB rays. The SPF number lets you know how much longer you can stay out of the sun without burning. For example, if it takes 15 minutes for a person to burn, an SPF 15 will allow them to stay out in the sun 15 times longer without burning.
The American Academy of Dermatology recommends wearing an SPF of 15 or higher for maximum protection. SPF is available in factors from 2-60. Does highest mean the best protection? Not necessarily. An SPF of 50 only provides 1-2% more protection than an SPF30.
UVA and UVB ProtectionThe label of the sunscreen will indicate the UVA or UVB protection.
UVA rays are responsible for the aging effect of the sun. However, overexposure to UVA rays can cause skin cancer.
UVB rays are responsible for sunburns and skin cancer.
Choose a product that has states "UVA/UVB" protection or has "broad spectrum" protectant.
Waterproof vs Water ResistantIf you are looking for a sunscreen to use while in the water, choose a sunscreen that is "waterproof" or "water resistant".
"Waterproof" sunscreen should provide protection in the water for 80 minutes, while "water resistant" provides only 40 minutes of protection.
