Abstract:
PURPOSE: A cosmetic composition for skin whitening is provided to sooth melanocyte and to seclude stimulation caused by inflammation, UV and melasma blood vessels. CONSTITUTION: A cosmetic composition for skin whitening includes Magnolia Obovata Bark Extract, Citrus Unshiu Peel Extract, Wild Soybean Extract, Ginko Biloba Leaf Extract or Honeysuckle Flower Extract as an active ingredient. 0.01-10 weight% of the Magnolia Obovata Bark Extract, Citrus Unshiu Peel Extract, Wild Soybean Extract, Ginko Biloba Leaf Extract or Honeysuckle Flower Extract is contained for the total weight. The composition additionally contains one or more from glucoside, glycyrrhiza extract, arbutin, ascorbic acid or kojic acid. The composition fundamentally secludes the production of melanin inside the skin or composition easily eliminates the melanin inside the skin. The composition improves chromatosis and skin tone down phenomenon. The composition reduces amount of the skin keratinocytes.
Abstract:
PURPOSE: A kit for detecting a skin active material and a detection method using the same are provided to quickly and simply screen antioxidative, whitening and moisturizing materials. CONSTITUTION: A kit for detecting a skin active material contains Klotho protein gene, primer for amplifying the gene of sequence numbers 1 and 2, a probe of sequence number 3, and a material which enhances Klotho protein expression level in skin cells. The skin active material is a material for moisturizing, anti-aging, or whitening. The skin cells are human keratinocytes, fibroblast, or melanocytes.
Abstract:
PURPOSE: A composition containing Homalium longifolium extract for skin whitening is provided to suppress c-kit protein activation and signal transduction in melanocytes. CONSTITUTION: A composition for skin whitening contains 0.0001-10 weight% of Homalium longifolium extract as an active ingredient. The Homalium longifolium extracts suppresses c-kit activation. The Homalium longifolium extract controls melanocyte function by suppressing signal transduction in melanocytes. The composition for skin whitening is used in the form of emulsion, cream, essence, pack, gel, powder, makeup base, foundation, lotion, ointment, body lotion, body cream, body oil, shampoo, rinse, soap, and hair dye.
Abstract:
A composition for regulating melanogenesis, which contains RhoGDI-alpha is provided to efficiently promote or inhibit melanogenesis using siRNA gene which suppresses RhoGDI-alpha expression. A composition for regulating melanogenesis comprises a RhoGDI-alpha protein or gene coding the same or a complementary gene of RhoGDI-alpha gene. The composition for regulating melanogenesis inhibits the expressions of MITF and tyrosinase. The composition for regulating melanogenesis promotes the expression of MITF and tyrosinase. A screening method of the composition for regulating melanogenesis includes confirmation of regulation of RhoGDI-alpha expression, activation or function.

Abstract:
The present invention relates to a method for screening effective substances related to skin-whitening, and more specifically, to a method which checks reduction of PGE_2 (prostaglandin E_2) generation related to melanin production and movement through measurement of a TRPM8 gene expression amount and screens substances effective to skin-whitening using the same.
