RT Journal Article SR Electronic T1 UV protection and sunscreens: What to tell patients JF Cleveland Clinic Journal of Medicine JO Cleve Clin J Med FD Cleveland Clinic SP 427 OP 436 DO 10.3949/ccjm.79a.11110 VO 79 IS 6 A1 Paul C. Jou A1 Ron J. Feldman A1 Kenneth J. Tomecki YR 2012 UL http://www.ccjm.org/content/79/6/427.abstract AB Ultraviolet (UV) radiation is the major environmental risk factor for nonmelanoma skin cancer and is a suspected risk factor for melanoma. Avoiding overexposure to direct sunlight during the peak daylight hours, wearing protective clothing, and applying sunscreen are ways to protect the skin. To provide clinicians with the tools to advise patients and to answer their inquiries, including which sunscreen to use, we review UV radiation’s effect on the skin, how sunscreens block UV light, current recommendations on sunscreen use, and new sunscreen labeling requirements.
