How can you prevent actinic keratosis?

The best way to prevent actinic keratosis is to reduce your exposure to the sun, especially during peak hours when sunlight is most intense. Here are some methods:

  • Wear long-sleeved shirts, pants, and a hat to protect areas of skin that might be exposed to the sun.
  • Apply a sunscreen with a sun protection factor (SPF) of 30 or higher at least 30 minutes before going outdoors. A broad-spectrum sunscreen is recommended to protect the skin from both ultraviolet A and B rays.
  • Avoid trying to get a tan by staying out in the sun or using tanning beds; use self-tanning products instead.
