Vitamin D levels in non-users of sunscreen versus once-daily sunscreen users: A retrospective analysis from a cosmetic dermatology center in South India

Abstract

Sun exposure and UV light are known causes of photoaging. Therefore, every cosmetic dermatologist’s prescription almost always includes sunscreen. A common perception is that regular usage of sunscreen drives the user to become Vitamin D deficient over a period of time. This has led to limited usage of sunscreen. We endeavored to evaluate any potential impact of such limited area use of sunscreens, on Vitamin D levels. It was found that Vitamin D levels did not correlate with limited sunscreen use which further indicates that, testing for Vitamin D deficiency at baseline, and adequate supplementation thereafter, are important, given the central role of Vitamin D in many dermatological conditions.
