MT-1, short for α-melanocyte-stimulating hormone analog, is a synthetic peptide hormone drug. By specifically binding to receptors on the surface of melanocytes, it precisely regulates melanin synthesis and distribution, with multiple biological activities including regulating skin pigmentation, anti-inflammation and immune modulation. Clinically, it is mainly used to treat skin diseases such as vitiligo and hypopigmentation, and can also assist in alleviating symptoms of certain inflammatory skin diseases. Mostly available in injection form, it must be used under the guidance of professional physicians. An allergy test is required before use, and it is contraindicated for those with allergies. For storage, it should be sealed, protected from light, and refrigerated at 2-8℃; freezing is strictly prohibited.
