How often should I apply sunscreen?

  If you are out in the sun try to reapply every 2 hours or after swimming or sweating. Wear sunscreen even on cloudy days  (if there is light the sun is out). Wear sunscreen even if you are spending your day in a car and or in a building with windows. Make sure you use a generous amount on exposed skin. Don't rely only on a make-up with sunscreen for full protection. Don't forget to protect  ears, back of neck, hands (both sides) and, if wearing shorts and sandals, legs and feet. These areas along with the face and scalp are where skin cancer is most commonly reported. For extra protection wear a hat and get regular facials. Lastly,  keep in mind that a sun tan is the first sign of skin damage.
