There appears to be a direct relationship between UV exposure and the development of photocarcinogenesis. Based upon the best current information available, a regimen of overall photoprotection which includes protective clothing, avoiding midday sun, and
regular use of broad-spectrum high SPF sunscreen should provide significant protection and appears to be reducing melanoma incidence rates. This is the current recommendation of the American Academy of Dermatology, Skin Cancer Foundation, and other major international organizations, and it is also the recommendation that is best supported by the existing data. There is no reason to recommend intentional sun exposure or decreased photoprotection to increase vitamin D levels as adequate incidental UV exposure occurs in day-to-day activities. Hopefully, we will have even more definitive answers to questions related to the optimization of effectiveness of sunscreens and other forms of photoprotection and for reducing the risk from exposure to UV radiation as improved photoprotective agents, strategies, and methods are developed in the future.
