👉 Melanoprinin, also known as melanocortin, is a hormone produced by the pituitary gland that regulates the development and function of skin cells in the body. It plays a crucial role in regulating the production of sebum, which is responsible for the formation of the skin's natural oil, and in maintaining the integrity of the skin barrier. Melanoprinin also affects the production of melanin, the pigment that gives the skin its color.
