Solar keratosis; Sun-induced skin changes - keratosis; Keratosis - actinic (solar)
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.
