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.
