In: Biology

Answer 1

Melatonan is a synthetic hormone that stimulates the production of melanin, which is the pigment that gives our skin its color. The more melanin we have, the darker our skin is. It does this by essentially imitating one of the natural hormones in our bodies that stimulate melanin production.
