Age spots (liver spots)

Prevention

To help avoid age spots and new spots after treatment, follow these tips for limiting your sun exposure:

  • Avoid the sun between 10 a.m. and 2 p.m. Because the sun's rays are most intense during this time, try to schedule outdoor activities for other times of the day.
  • Use sunscreen. Fifteen to 30 minutes before going outdoors, apply a broad-spectrum sunscreen with a sun protection factor (SPF) of at least 30. Apply sunscreen generously, and reapply every two hours — or more often if you're swimming or perspiring.
  • Cover up. For protection from the sun, wear tightly woven clothing that covers your arms and legs and a broad-brimmed hat, which provides more protection than does a baseball cap or golf visor.

    Consider wearing clothing designed to provide sun protection. Look for clothes labeled with an ultraviolet protection factor (UPF) of 40 to 50 to get the best protection.
