How does skin relate to vitamin D?

The human skin acts as site of synthesis of vitamin D and also as target organ for the biologically active form of this vitamin. Vitamin D affects multiple functions in the skin ranging from keratinocyte proliferation, differentiation, and apoptosis to barrier maintenance and immunoregulatory processes [1].

What is the relationship between vitamin D and the skin?

Results: Vitamin D is integrally connected to the skin for its synthesis, metabolism, and activity. It regulates many physiological processes in the skin ranging from cellular proliferation, differentiation, and apoptosis to barrier maintenance and immune functions.
