| − | Hormones have a large effect on the skin, details of which can be found at [[Endocrine & Nutritional Influences on the Skin|endocrine and nutritional influences on the skin]]. As a result, [[Endocrine effects on the skin - Pathology|endocrine associated skin pathology]] is relatively common.

| − | The skin is a producer of '''vitamin D''', the precursor of the hormone, [[Calcium#Calcitriol (Active Vitamin D3)|calcitriol]]. Ultraviolet light at a wavelength of 300nm is required to convert ''7-dehydrocholesterol'' to Vitamin D. Whilst this is a key source of the vitamin in humans, as many animal species have hair covered skin, Vitamin D from this region is usually minimal, with dietary sources being much more important. Vitamin D is then hydroxylated into its active form, [[Calcium#Calcitriol (Active Vitamin D3)|calcitriol]] in the [[Kidney Endocrine Function - Anatomy & Physiology|kidney.]]
