Abstract: The present invention relates to a cosmetic composition for whitening comprising a Caragana sinica root extract, and more specifically relates to a cosmetic composition having an outstanding skin-whitening effect, the composition comprising a Caragana sinica root extract, a fraction thereof or ?-viniferin isolated therefrom. In the present invention, the Caragana sinica root extract, fraction thereof or ?-viniferin isolated therefrom inhibits tyrosinase activity and suppresses melanin production and is therefore effective in skin whitening.

Abstract: The present invention relates to a cosmetic composition for wrinkle reduction comprising, as an active ingredient, a Gynostemma pentaphyllum gypenoside fraction and, more specifically, to a cosmetic composition for wrinkle reduction, wherein the Gynostemma pentaphyllum gypenoside fraction includes at least one gypenoside selected from the group consisting of gypenoside UL1, gypenoside UL2, gypenoside UL3, gypenoside UL4, gypenoside UL5, gypenoside UL6, and gypenoside UL7.

Abstract: The present invention relates to Nelumbo nucifera callus having an increased content of gallic acid or an extract thereof and to a method for preparing the same. The Nelumbo nucifera callus extract according to the present invention has an excellent whitening effect by containing a large amount of gallic acid, and thus can be advantageously used as a cosmetic composition.

Abstract: The present invention relates to a composition comprising natural plant extracts for alleviating inflammation caused by yellow dust and fine particulate, wherein the plant extracts of the present invention inhibit a production of NO caused by the yellow dust and fine particulate and a production of inflammatory cytokines, thus having an excellent effect on preventing or alleviating skin inflammation caused by the yellow dust, fine particulate and other harmful substances.

Abstract: Disclosed is a cosmetic composition having a double-shell type nano-structure. More particularly, the nano-structure of the cosmetic composition includes: a water-soluble bioactive ingredient core; a core shell containing poly(ethyleneglycol)-poly(caprolactone)-poly(ethyleneglycol) (PE-PCL-PEG) triblock copolymer in order to include the bioactive ingredient core therein; and an outer shell containing phospholipids or derivatives thereof in order to enclose the core shell therein. Such a cosmetic composition improves stability of active components which are prone to oxidation, light degradation, heat degradation, etc., is formed in a nanoparticle size which in turn shows high transdermal absorption and is very useful to prepare a cosmetic composition stably encapsulating various bioactive ingredients with anti-wrinkle effects, whitening effects, and so forth.
