Prevention:

Ways to prevent actinic keratosis:

• Reduce sun exposure and protect your skin from the sun.
• Wear protective clothing such as hats, long-sleeved shirts, long skirts, or pants.
• Try to avoid sun exposure during midday, when ultraviolet light is most intense.
• Use high-quality sunscreens, preferably with SPF (sun protection factor) ratings of at least 15. Pick a sunscreen that blocks both UBA and UVB light.
• Apply sunscreen at least 30 minutes before going out into the sun, and reapply frequently.
• Use sunscreen year-round, including in the winter.
