Administration	Subcutaneous	Subcutaneous
Mechanism	Also known as Afamelanotide, this melanocortin receptor agonist induces skin pigmentation and provides photoprotection. FDA-approved for erythropoietic protoporphyria (EPP) under the brand name Scenesse.	Melanotan II is a synthetic analog of the peptide hormone alpha-melanocyte-stimulating hormone (α-MSH). It stimulates melanogenesis, leading to skin tanning without UV exposure. It also has effects on libido and appetite.
