Abstract:
The present invention provides a novel pseudo-ceramide compound represented by Chemical Formula 1, an isomer, a pharmaceutically allowable salt, a pro-drug, a hydroxide, or a solvated compound thereof. [Chemical Formula 1] (In Chemical Formula 1, R1 and R2 are independently non-substituted or hydroxyl group-substituted C 9 to 23 saturated or unsaturated aliphatic chains.) According to the present invention, the compound has excellent stability and dissolubility and is effective in moisturizing the skin so as to protect the skin from external stimuli without side effects and be used as an active ingredient for recovering damaged skin and preventing skin damage. Accordingly, the compound can be used as an external skin application composition for moisturizing the skin, as a cosmetic composition, or as a pharmaceutical composition.
Abstract:
The present invention relates to an inorganic powder coated with a biocompatible polymer and a cosmetic composition containing the same, and more specifically, to an inorganic-organic hybrid powder having improved dispersibility and tactile sensation by treating a rough surface of an inorganic powder with a biocompatible polymer, and to a cosmetic composition having improved tactile sensation and adhesiveness when applied to the skin by containing the hybrid powder.

Abstract:
PURPOSE: Carnosic acid, a derivative thereof, or a pharmaceutically acceptable salt thereof is provided to suppress elastase activation or matrix metalloproteinase-9 (MMP) expression, and to basically inhibit vital reaction mediated by the suppression. CONSTITUTION: An elastase activation inhibitor contains carnosic acid of chemical formula 1, a derivative thereof, or a pharmaceutically acceptable salt thereof as an active ingredient. The carnosic acid derivative is carnosic acid methyl ester or carnosic methyl alcohol. The carnosic acid, the derivative, or the pharmaceutically acceptable salt is derived from rosemary and/or sage. The inhibitor contains 0.0001-20 wt% of the active ingredient. An MMP expression inhibitor contains the carnosic acid, the derivative, or the pharmaceutically acceptable salt as an active ingredient. A composition for skin anti-aging contains the carnosic acid, the derivative, or the pharmaceutically acceptable salt as an active ingredient.
Abstract:
PURPOSE: A composition containing an enzyme-treated Codonopsis lanceolata extract is provided to shorten hair growth period, and to promote hair growth. CONSTITUTION: A composition for promoting hair growth contains 0.001-20 wt% of enzyme-treated Codonopsis lanceolata extract as an active ingredient. The extract is treated with a cel-wall decomposing enzyme or a protease. The enzyme is cellulase or pectinase. [Reference numerals] (AA) Example 1; (BB) Comparative example 1;
Abstract:
PURPOSE: A method for screening a material which recovers skin barrier function of atopic skin through controlling expression of fatty acid elongase and carbon chain is provided to detecting ceramide fatty acid and to accurately screen skin improving substances. CONSTITUTION: A method for screening a material for treating atopic dermatitis comprises: a step of identifying expression level of elongase in keratinocytes treated with candidate materials; and a step of determining a material which enhances the expression level of the elongase as a material which improves atopic dermatitis. [Reference numerals] (AA) Score; (BB) Control group;
Abstract:
PURPOSE: A composition containing an esculin derivative is provided to suppress tyrosinase activity and melanogenesis and to ensure an excellent skin whitening effect. CONSTITUTION: A composition for skin whitening contains an esculin derivative of chemical formula 1, an isomer thereof, a pharmaceutically acceptable salt thereof, a prodrug thereof, a hydrate thereof, or a solvate thereof as an active ingredient. In chemical formula 1, R is selected from a group consisting of C1-C30 alkyl, C2-C30 alkene, C3-C30 cycloalkyl, and C1-C30 haloalkyl.
