摘要

by E. Alia, P.E. Kerr delete this edited stuff. I don't know from where this is orig-inating Vitamin D is a steroid hormone of importance to the field of dermatology. Skin is unique in that it is the site of vitamin D synthesis upon sun exposure , a target organ for its activity. We explore the physiology and metabolic mechanism of action of vitamin D, as well as its effects on the skin. We also discuss the current evidence of the efficacy and safety of oral and topical vitamin D analogues on skin conditions such as psoriasis, atopic dermatitis, vitiligo, sunburn, actinic keratosis , fibrosing skin disorders. Based on currently available scientific evidence, the National Academy of Medicine's recom-mended dietary allowance for vitamin D ranges from 400 IU to 800 IU daily based on age categories.
