Prevention of actinic keratoses should ideally begin early in life. Sun damage to unprotected skin begins in childhood, and children who live in geographic areas that receive high-intensity sunlight are at an increased risk. No matter your age, it is never too late to begin AK prevention.

The basics of AK prevention are:

• Avoid excessive exposure to sunlight. Stay out of direct sun exposure during peak (10a.m.- 4p.m.) sunlight hours.
• Use a broad-spectrum sunscreen with a SPF of 15 or higher. Broad-spectrum sunscreen provides protection from both the UVA and UVB rays of the sun. Apply broad-spectrum sunscreen at least 15 to 30 minutes before going outdoors, even on cloudy days.
• Reapply sunscreen every two hours. When outdoors and even on cloudy days, be sure to reapply sunscreen every two hours.
• Wear protective clothing. When outdoors during daylight, wear a wide-brimmed hat, sunglasses that block 100% of the UV rays and tightly knit clothing that covers arms and legs.

Consult your dermatologist regarding your individual needs for maximum sun protection.
