How can I prevent actinic keratosis?

The best way to prevent actinic keratosis is to avoid prolonged UV exposure. You can protect your skin by:

• Applying sunscreen every day, even in cloudy weather or during winter, and re-applying often — at least every two hours. Use a broad-spectrum sunscreen with at least 30 sun protection factor (SPF) that blocks both UVA and UVB light.
• Avoiding sun exposure when UV light is most intense, between 10 a.m. and 2 p.m.
• Avoiding tanning salons, sun lamps and tanning beds.
• Wearing sun-safe clothing, such as long-sleeved shirts, long pants and hats.
