Staying away from overexposure to sun is one of the important preventive techniques. Sun protection reduces one's risk of developing skin cancer and also decreases the likelihood of recurrence.
Use a high-factor sunscreen (SPF 30 or above) whenever you are exposed to the sun. It should have a broad spectrum offering protection against ultraviolet A (UVA) and ultraviolet B (UVB) rays. Follow the instructions on the bottle and re-apply as recommended, particularly after profuse sweating and swimming.
Wear clothing made of cotton or natural fibers, which are closely woven and offer good protection against the sun.
Stay out of the sun during the hottest part of the day - usually between 10am and 4pm.
Avoid Tanning beds and sunlamps because they too emit enough UV radiation, which can cause skin cancer.
Get vitamin D safely through a healthy diet that includes vitamin supplements.
Use sunglasses with 99% to 100% UV absorption to provide optimal protection for the eyes. Wear a wide-brimmed hat to protect your face and neck.
Use extra caution near water, snow, and sand as they reflect the damaging rays of the sun.
Follow these practices to protect your skin even on cloudy or overcast days. UV rays travel through clouds. Do not use sunscreen on children under 6 months of age.
