The present invention relates to novel melanocytes and melanoblasts. In addition, the present invention relates to a novel method for producing melanocytes and melanoblasts. Specifically, provided is novel melanocytes of which gene expression, melanin content, and tyrosinase activity are different from those of conventional melanocytes. Even more specifically, provided is novel melanoblasts of which the gene expression, the melanin content the tyrosinase activity, and the protein expression are different from those of conventional melanocytes. Additionally, provided is a novel method for producing melanocytes or melanoblasts by culturing keratinocytes.

Melanocyte or progenitor cell thereof adapted to keratinocyte, and preparation method thereof

The present invention relates to a composition containing a chemokine, particularly, an interferon-inducible T-cell alpha chemoattractant (ITACT) which can decrease the gene expression of a factor related to melanin pigment production in melanocytes, thereby exhibiting a skin whitening effect.

Method for skin whitening using chemokine

Provided is a cosmetic composition for improving skin elasticity containingextract and a polymersome in which an anti-aging peptide is stabilized as active ingredients. The cosmetic composition of the present disclosure is efficacious in improving skin wrinkles, restoring skin elasticity and increasing skin water content, and thus is effective for improving skin elasticity.

Cosmetic composition for improving skin elasticity

The present invention relates to a method for calculating a thermal protection factor, wherein the method comprises the steps of: applying heat to a first area coated with a thermal protection material, and a second area not coated with the thermal protection material; measuring the respective saturation temperatures of the first area and second area; calculating a first energy by dividing the energy corresponding to the heat applied to the first area by the saturation temperature of the first area; calculating a second energy by dividing the energy corresponding to the heat applied to the second area by the saturation temperature of the second area; and calculating the thermal protection factor of a thermal protection material by dividing the first energy by the second energy or dividing the difference between the first energy and the second energy by the first energy.

Method for calculating a thermal protection factor

Disclosed is a composition for a whitening effect or for the prevention of gray hair, which includes antisense nucleic acid molecules of SEQ ID NO: 2, wherein the composition has an miRNA of SEQ ID NO: 1 or a base sequence complementary thereto. Also disclosed is a method for controlling chromogenesis in test materials and for screening for expression control materials of chromogenic genes. The composition and the screening methodcan be used for the whitening effect or for the prevention of gray hair.
