Dr. Holly Phillips Recommends How to Protect Your Skin From Cancer-Causing Rays

According to Dr. Holly Phillips, most skin cancers are caused by too much exposure to ultraviolet light. UV rays can even damage skin cells on cloudy and cool days. Dr. Phillips recommends using broad spectrum sunscreens with an SPF of 15 or higher, reapplying at least every two hours and more often if you're swimming or sweating. This advice applies to people of all skin colors. Those who take any medications should ask their doctors if they could increase sun sensitivity.
