The invention provides a polypeptide composition for skin whitening and spot relieving. The polypeptide composition comprises an MC1-R antagonist (namely an alpha-MSH competitive antagonist) and/or a composition of polypeptides inhibiting alpha-MSH expression and/or a tyrosinase inhibitor. The polypeptide composition can reduce the generation of melanin, and contributes to skin brightening, so as to achieve the purposes of relieving color spots (chloasma, butterfly rash, freckle and the like), improving sallow tone and whitening skin. The concentration of each polypeptide is 0.0001-5%. The polypeptide composition provided by the invention can be prepared into various beauty and skin-care products as well as medical products.
