Both melanocyte-stimulating hormone and Î±-MSH are capable of stimulating melanin production in sun exposed areas under the action of ultraviolet light. Prolonged dosages of Î±-MSH, however, will not only increase pigmentation of the skin, but may also cause hypertrichosis (excessive hair growth) and skin atrophy.
