Does vitamin D produce melanin?

Melanin has photoprotective action and protects the skin from harmful effects of ultraviolet radiations. High melanin level inhibits the production of vitamin D in the skin. Vitamin D is a prohormone that helps in the absorption of calcium from the gut. Deficiency of vitamin D leads to many threats.

Where is melanin located?

Melanin is formed primarily in the melanocyte, located in the inner layers of the skin where melanin and carotene blend to produce the skin color as well as the color in the eyes and hair. Red hair is produced by pheomelanin in spherical melanosomes (melanin granules).

African and Indian skin had the highest total amount of melanin in the epidermis (t-test; P < 0.001), with no significant differ- ence between them. Amongst the remaining lighter groups, there was no significant difference in total epidermal melanin content.

What causes melanin deficiency?

Do Asians have melanin?

In these studies Asians had the least hyperpigmented spots. So it appears that Far East Asian subjects have mechanisms other than melanin photoprotection to reduce the negative effects of UV irradiation on skin.
