Peptide, method and composition for stimulating melanogenesis
An isolated peptide for stimulating melanogenesis in a mammal subject is provided. The isolated peptide consisting of an amino acid sequence of FKCRRWQWRMK KLGAPSI (SEQ ID NO: 1). Also provided are methods and compositions for stimulating melanogenesis in a mammal subject.
1. A composition for stimulating melanogenesis in a mammal subject, comprising an effective amount of a peptide consisting of the amino acid sequence of SEQ ID NO: 1, which is formulated as a topical formulation in the form of an ointment, lotion, cream, gel, shampoo or hair conditioner.
2. The composition of claim 1 , further comprising a physiologically acceptable carrier.
3. The composition of claim 1 , wherein the topical formulation is a shampoo.
4. The composition of claim 1 , wherein the topical formulation is a hair conditioner.
5. The composition of claim 1 , which is effective for darkening the hair color in a human subject.
6. A method for darkening the hair color in a human subject, which comprises administering to said subject an effective amount of the composition of claim 1 in the amount effective to stimulate melanogenesis in the human subject or melanocytes.
7. The method of claim 6 , wherein the melanin content is increased through the stimulation of melanogenesis by the composition.
8. The method of claim 6 , wherein the composition is administered to the subject topically.
