A composition contains, as an effective component, theasinensin A, an enantiomer thereof, a pharmaceutically acceptable salt thereof, a hydrate thereof, or a solvate thereof. The composition has an excellent stability and provides wrinkle-reducing or skin elasticity-enhancing benefits, and skin-brightening benefits by containing theasinensin A, an enantiomer thereof, a pharmaceutically acceptable salt thereof, a hydrate thereof, or a solvate thereof, as an effective component.

Cosmetic composition comprising theasinensin A

The present specification discloses a composition for external application to skin, containing a tea plant root extract as an active ingredient, for treatment of skin damage caused by fine dust, whereby the expression level of one or more selected from a group consisting of IL-36G (NM_019618), S100A7 (NM_002963), S100A8 (NM_002964) and XDH (NM_000379), which are genes in skin cells the expression level of which is affected by fine dust, is regulated to a normal level.

Method for treatment of fine dust-caused skin cell damage, reinforcement of skin barrier, anti-aging, and anti-inflammation

The present specification relates to a method for extracting a plant by using a skin serum that can be used for skin care. This method can further increase the process efficiency and extract active ingredients more effectively than conventional extraction methods using a solvent. Thus, the method can increase customer satisfaction and promote the development of relevant industries.

Method for producing cosmetic composition using skin serum

Disclosed in the present specification are: a composition for preventing hair loss or promoting hair growth, containing-derived exosome-like vesicles; and a method for preparing the composition. The-derived exosome-like vesicles can have a diameter of 20-500 nm and can be isolated fromroot. The composition contains-derived exosome-like vesicles as active ingredients, thereby having an effect of inducing hair growth by activating dermal papilla cells (DPCs).

Composition for preventing hair loss or promoting hair growth, containing ginseng-derived exosome-like vesicles

Disclosed are: a lightening composition comprising ginseng-derived exosome-like vesicles; and a method for producing the ginseng-derived exosome-like vesicles. The ginseng-derived exosome-like vesicles may have a diameter of between 20 and 500 nm, and may be isolated from ginseng root. Because the composition comprises the ginseng-derived exosome-like vesicles as an active ingredient, said composition is effective in preventing, improving or treating skin pigmentation conditions such as liver spots, freckles, lentigo, birth marks and melanoma by effectively suppressing the production of melanin.
