Abstract: The present invention relates to a method for stabilizing ceramide and to a cosmetic composition containing stabilized ceramide and, more specifically, to a method for homogenizing and stabilizing ceramide by self-assembling the ceramide together with ?-sitosterol, resveratrol, and allantoin which are other physiologically active substances using a microfluidic chip and a high pressure homogenizer, and to a technique for using ceramide and nanoparticles containing ?-sitosterol, resveratrol, and allantoin, which are produced by means of the stabilizing method, as a cosmetic material for skin moisturizing, anti-oxidation, skin inflammation relief, skin barrier enhancement, and skin itching relief.

Abstract: The present invention relates to a lipid-based nanoparticle composition for enhancing transdermal absorption and a method of preparing the same. The present invention provides a carrier for enhancing transdermal absorption that enhances or promotes chemical bonding with skin tissue by modifying the surface of lipid nanoparticles with a polyphenol. This may demonstrate the synergistic effect of active and passive transdermal delivery systems.

Abstract: Disclosed is a skin preparation composition for external use containing complex hyaluronic acid as an active ingredient, and specifically relates to a skin preparation composition for external use that contains hyaluronic acid, sodium hyaluronate, and hydrolyzed hyaluronic acid as active ingredients, and are excellent in an active oxygen scavenging effect, a wrinkle improvement effect, a moisturizing effect, a skin irritation relief effect, an acne prevention effect, an atopy improvement effect, and an anti-inflammatory effect, an hair damage prevention effect, and a hair loss prevention and hair growth effect.

Abstract: Provided is a cosmetic composition for skin moisturization containing a hydrolyzate extract obtained by adding a protease to the fruit of Cicer arietinum, a Rhododendron chrysanthum leaf extract and a Tricholoma matsutake extract. The cosmetic composition exhibits excellent effects on cell moisturization, intercellular moisturization and skin-barrier moisturization. In addition, the cosmetic composition is harmless to the human body and has excellent stability because it uses natural substances.
