Vitamin D always acts via its specific VDR receptor, expressed by different skin cells, including keratinocytes. In the epidermis, the VDR is mainly expressed in the basal layer, diminishing with increased epidermal differentiation. VDR levels determine the ability of the cell to respond to vitamin D. Vitamin D is essential for maintaining skin health and is vital for regulating the skin’s barrier function or immunity against infection. In terms of sun protection efficiency, SPF 8 is believed to block vitamin D production in the skin by up to 95%. Vitamin D levels acquired during the summer months decrease by half in about two months, making people more susceptible to disease.
