(HealthDay News) -- Sunscreen is one of the most effective ways to protect your skin from the harmful effects of the sun -- but only if it's applied properly.
Sunscreens come in a variety of forms, including sprays, creams, gels, and sticks. As long as a few basic guidelines are followed, any of these types can be an effective way to avoid sunburn and damage to your skin.
Even if the day is mostly overcast, the sun's harmful rays can still reach your skin. The American Academy of Dermatology recommends wearing a
water-resistant sunscreen of at least SPF 15 any time you will be outdoors
for 20 minutes or more.
You should apply sunscreen by rubbing it in thoroughly at least 15-30 minutes
prior to going outside, and reapply every two hours after that. Be sure not
to miss any of the often-forgotten spots on your body that are susceptible to the sun, including lips, ears and feet.
