title: The science behind sunscreens.
abstract: Exposure to ultraviolet light is a well-documented cause of immunosuppression, matrix degradation, premature facial aging, and skin cancer. Because sunscreens can limit ultraviolet-induced skin damage and production of matrix metalloproteinases, they are accepted as the most active and beneficial of antiaging products. Understanding the variety of ingredients available, and their individual advantages and disadvantages, will allow a clinician to make more informed recommendations regarding the use of sunscreens.
