    Abstract: A system and a method for measuring ultraviolet ray protection of a cosmetic material. In an embodiment, the system for measuring the ultraviolet ray protection of a cosmetic material includes: a light source for emitting light including ultraviolet bands; a transparent plate through which the lights emitted from the light source pass, and having one surface to which a cosmetic material to be tested is applied; a wavelength conversion film, which changes, to a predetermined size, the light, of an ultraviolet band, of the light having passed through the transparent plate and makes the same pass therethrough; and a photosensitive sheet, which accommodates the light having passed through the wavelength conversion film and has a photosensitive property for light of UVA and UVB bands among the ultraviolet bands.

    Abstract: The present disclosure relates to a composition comprising (20S,24R)-6-O-β-D-glucopyranosyl(1→2)-β-D-glucopyranoside-dammar-3-one-20,24-epoxy-6a,12b,25-triol, which is a novel ginsenoside, a pharmaceutically acceptable salt thereof, a hydrate thereof or a solvate thereof as an active ingredient. In addition, it relates to a method for improving skin elasticity or skin wrinkles, which comprises administering an effective amount of (20S,24R)-6-O-β-D-glucopyranosyl(1→2)-β-D-glucopyranoside-dammar-3-one-20,24-epoxy-6a,12b,25-triol, a pharmaceutically acceptable salt thereof, a hydrate thereof or a solvate thereof to a subject in need thereof. The novel ginsenoside, a pharmaceutically acceptable salt thereof, a hydrate thereof or a solvate thereof has a superior effect of improving skin elasticity and skin wrinkles.

    Abstract: One aspect of the present disclosure is a cosmetic composition containing a solubilized pigment and a method for preparing the same. More specifically, the cosmetic composition containing the solubilized pigment may be prepared through a process of dissolving a pigment in an aqueous phase by dispersing the pigment in the aqueous phase using a pigment dispersing thickener and stabilizing by further increasing the viscosity using a stabilizing thickener. Since the solubilized pigment exhibits dyeing properties similar to dyes, it can be widely applied to various cosmetic compositions.
