Peptides that increase melanin synthesis are provided. These peptides include pentapeptides YSSWY (SEQ ID NO: 1), YRSRK (SEQ ID NO: 2), and their variants. The peptides may activate the enzymatic activity of tyrosinase to increase melanin synthesis. The pharmaceutical, cosmetic, and other compositions including the peptides are also provided. The methods of increasing melanin production in epidermis of a subject are provided where the methods include administering compositions comprising an amount of one or more peptides effective to increase the melanin production. The methods also include treating vitiligo or other hypopigmentation disorders with compositions including one or more peptides.

Peptide tyrosinase activators

Disclosed are peptides that inhibit the enzymatic activity of tyrosinase, as well as formulations and methods for their use in the reduction of skin pigmentation, and methods of administering the inhibitory pep tides in a topical formulation. Preferred octapeptide sequences are internally rich in tryptophan and/or tyrosine or arginine. The present invention is further directed to kits and compositions containing the present peptides, and methods of treatment of conditions involving expression of tyrosinase, in which the present peptides are administered topically for the treatment of conditions involving melanocyte activity in the skin.
