Broad-spectrum sunscreen, shade and protective clothing work together to guard your skin, and here is how to use them well.

Sun protection is one of the most effective things you can do for your skin, and it matters on cloudy days and in cooler months too. Ultraviolet (UV) rays can harm skin even when you do not feel hot.

The American Academy of Dermatology recommends a broad-spectrum, water-resistant sunscreen with an SPF of 30 or higher on all exposed skin. Apply it generously and reapply about every two hours, or sooner after swimming or sweating.

  • Seek shade when the sun is strongest, usually around midday.
  • Wear a wide-brimmed hat, sunglasses and tightly woven clothing.
  • Remember ears, neck, hands and the tops of your feet.

See a doctor or dermatologist if you notice a new mole, a spot that changes in size, shape or color, or a sore that does not heal.
