Abstract:
The present specification discloses a composition for caring for skin damage caused by fine dust, wherein the composition includes a fermented tea extract as an active ingredient and adjusts the expression level of at least one selected from the following group of genes which are present in skin cells and have expression levels that are affected by fine dust to normal levels, said group consisting of: IL-1B (NM_000576), IL-36G (NM_019618), S100A7 (NM_002963), LCE3D (NM_032563), PTGS2 (NM_000963) and XDH (NM_000379). Damage to skin cells can be cared for by using the composition for caring for skin damage caused by fine dust to return gene expression levels, which change due to fine dust, to normal levels.
Abstract:
Disclosed in the present specification are a method for preparing senescent melanocytes, senescent cells prepared by the preparation method and a method for screening a senescence-alleviating or skin whitening material by using the senescent cells. The cells can be used for studying a cell senescence phenomenon and a pigmentation mechanism, which are caused by the accumulation of UV ray stimulation. Particularly, the cells are useful since a material having both senescence-alleviating and skin whitening effects can be screened.
Abstract:
The present specification discloses a biomarker for diagnosing skin cell damage caused by fine dust, a kit using the same, and a novel use of a composition comprising galangin as an active ingredient. Specifically, it is possible to conveniently check skin damage caused by fine dust by measuring and comparing the expression amounts of the biomarker in normal cells and cells damaged by fine dust. In addition, a composition of the present invention comprising galangin, an isomer thereof, a pharmaceutically acceptable salt thereof, a prodrug thereof, a hydrate thereof or a solvate thereof as an active ingredient can normalize the gene expression of skin damaged by fine dust and promote differentiation of skin keratinocytes, thereby having a skin moisturizing or skin-barrier strengthening effect. Accordingly, since the composition can be used to prevent, treat, or alleviate skin diseases such as atopy, psoriasis, etc. the composition is useful.
Abstract:
This specification provides a light source radiation apparatus for radiating light, a kit for lipolysis having a manual describing a method for dissolving fat by radiating light, and a slimming method for radiating light to skin. According to the specification, the present invention can dissolve neutral fat in a fat cell by radiating light of a wavelength in a range of light harmless to the body, thus can safely and effectively dissolve fat, and can be used for the slimming method by having the advantage of being more economical and convenient than a conventional lipolysis method.
Abstract:
The present specification discloses a composition comprising a Scutellaria alpina extract as an active ingredient. The composition disclosed in the present specification exhibits the effect of reducing melanogenesis or inhibiting tyrosinase activity by comprising the Scutellaria alpina extract. As a result of the effect, the Scutellaria alpina extract of the present specification can exhibit a whitening effect and thus can be widely used as a whitening composition in the field of pharmaceuticals or cosmetics.
Abstract:
Provided in the present invention are adult stem cells derived from human skin dermis, and a method for isolating same. Further provided in the present invention are osteoblastic cells and adipocytes differentiated from the adult stem cells derived from human skin dermis, and a differentiation method therefor. Further provided in the present invention is a composition for osteogenesis or lipogenesis containing the stem cells, osteoblastic cells, or adipocytes. The isolation method of the present invention enables the adult stem cells derived from human skin dermis to be obtained in an easy and simple manner at a high yield rate. Genes and growth factors which are specifically expressed in the adult stem cells derived from human skin dermis isolated using the method can be separated, identified, and used later.
Abstract:
The present invention relates to a composition containing a Scutellaria alpina extract as an active ingredient. The composition of the present invention exhibits effects of reducing the amount of endothelin 1 by containing a Scutellaria alpina extract, and reducing the overexpression of NK1R and EDN1 genes. Therefore, the Scutellaria alpina extract of the present invention can exhibit, by said effects, skin homeostasis maintenance and anti-stress effects, and thus can be widely used as a composition for maintaining skin homeostasis in the pharmaceutical or cosmetic field.
