MELANINIZATION INHIBITOR, SKIN-CARE PREPARATION, AND BATH AGENT

摘要

A melaninization inhibitor and a skin preparation which has an excellent function of preventing chromatosis caused by inflammation through selective inhibition of irritation of melanocytes by histamine. The above function can be attained by using either a histamine H2 receptor antagonist capable of selectively blocking a histamine H2 receptor or the histamine H2 receptor antagonist in combination with at least one member selected from among histamine liberation inhibitors and histamine H3 receptor agonists.
