Sunscreens
Sunscreens provide protection by absorbing, reflecting or scattering the sun's rays. They may also contain chemicals that interact with the skin to protect it from UV rays. Sunscreens are rated according to their effectiveness by the sun protection factor (SPF). A product's SPF number helps determine how long the product will protect you before you need to re-apply it - how long you can stay in the sun without burning.
For example, you may normally burn in 20 minutes. If you apply an SPF 15 sunscreen, you'll be protected for about 300 minutes, or five hours (SPF 15 x 20 minutes = 300 minutes). A person with lightly pigmented skin who burns in 10 minutes would be protected for only about two-and-a-half-hours with SPF 15 (SPF 15 x 10 minutes = 150 minutes).
Sunscreens with SPF numbers higher than 15 may work well for people who have lightly pigmented skin, live at high altitudes, or work or play outdoors much of the day. To get the most protection from your sunscreen, apply it liberally at least 30 minutes before going outside and remember to re-apply it after swimming or perspiring heavily. If you're taking medication, ask your doctor or pharmacist if it will make your skin more sensitive to the sun.
You should always wear a sunscreen with at least SPF 15, no matter what your skin color. Even people with very dark skin can burn and develop skin cancer. Shop for sunscreen http://bit.ly/JnRp4u
