    Abstract: Provided are a method for preparing cationic liposomes by using a high-pressure emulsification device, cationic liposomes prepared by the method, and a cosmetic composition, a food composition and a pharmaceutical composition, comprising the cationic liposomes. According to the method for preparing cationic liposomes, toxic organic solvents are not employed and thus it is possible to produce liposomes safe for the skin at mass scale by using a high-pressure emulsification device. In addition, the cationic liposomes prepared by the above method have excellent formulation stability, and are positively charged, so that the skin absorption ability of active ingredients loaded therein may be enhanced. Therefore, the cationic liposomes can be used in cosmetics, foods, drugs, and the like.

    Abstract: A method of preparing a vesicle for skin absorption enhancement, a vesicle prepared using the method, and a cosmetic composition including the vesicle are provided. The vesicle preparation method may provide a skin absorption enhancement effect and may be used to prepare vesicles with improved formulation stability. The vesicle prepared using the method may be safe without skin irritation and have an improved skin absorption effect due to the use of a ceramide as a skin absorption enhancer, and may have improved formulation stability due to use of a nonionic surfactant and a phospholipid. Accordingly, the vesicle may be used in cosmetic compositions for enhancing skin absorption of bioactive ingredients such as functional ingredients.
