Provided is a cosmetic composition including organic-inorganic composite particles for blocking near-infrared rays. When the cosmetic composition for blocking near-infrared rays according to the present disclosure is applied to skin, light in the near-infrared region may be significantly blocked. The cosmetic composition may be used as a multifunctional product in combination with a UV-blocking material to block a wide range of wavelengths adversely affecting the skin, thereby preventing skin aging.

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.
