Recently I quizzed you all on the differences between UVA and UVB rays, but knowing the difference isn't enough to protect your from the sun's harmful rays. Nope...you need sunscreen and broad spectrum sunscreen at that. When you are buying your first bottle or tube of sunscreen this season, read the label and make sure it says that it protects from both types of rays - that it is Broad Spectrum.
The Mayo Clinic recommends that your sunscreen contain at least one of the following ingredients: oxybenzone, sulisobenzone, avobenzone (Parsol 1789), ecamsule, titanium dioxide or zinc oxide. The first four ingredients are chemicals that absorb the sun's rays before they can penetrate the skin. The final two ingredients physically block the sun's rays so they cannot penetrate your skin.
Fit's Tip: Remember to apply sunscreen regularly if you are outside for a long period of time especially in high humidity, sweating, or swimming.
