OLI-2168

Hydrolyzed Conchiolin Protein. Acts as a lightening agent. It is the peptide compound that enzymolyzed and separated from the conchiolin protein of aquatic organism by the bio-engineering technology, shows outstanding anti-melanogenesis caused by the endothelin. After the human skin is irradiated by the ultra violet ray(UVB), the keratin cells would liberate out endothelin. After the information of the endothelin have been accepted by the receiptor on the membrane of the melanocyte, it stimulates for differentiation and proliferation of the melanocyte, and activates the activity of the tyrosinase, and causes amount of melanin increasing rapidly. Endothelin Antagonist can regulate the information network effect of endothelin, and can inhibit the increase of melanin. Used in skin lightening preparations.
