Sunscreens and Photoprotection

Overview

Encouraging photoprotection is the leading preventative health strategy employed by physicians involved in skin care. Although sun avoidance is most desirable, outdoor occupations and lifestyles make total avoidance impossible for many individuals. The regular use of sunscreens represents a practical compromise in this regard. Sunscreens prevent the formation of squamous cell carcinomas in animals. In humans, the regular use of sunscreens has been shown to reduce actinic keratoses, solar elastosis, and squamous cell carcinoma.
The routine use of sunscreens may also reduce melanoma risk.
Drug photosensitization and photo-induced or photo-aggravated dermatoses may be prevented with sunscreen use, especially with products that offer better blockage in the UV-A range.
