The utility model discloses a magnetic adsorption structure of a make-up mirror, which comprises a mounting surface for attaching the make-up mirror and a make-up mirror body, the make-up mirror bodycomprises a shell and a mirror surface arranged on the shell, a first magnet is arranged inside the shell or on the surface of the shell, and a magnetizer attracted with the first magnet is arranged on the mounting surface. Compared with the prior art, the cosmetic mirror has the advantages that a new mechanical structure is utilized, a magnetic adsorption structure is adopted, double-hand make-upor make-up supplementation is facilitated, and the cosmetic mirror can be directly taken down from the installation face to be folded and carried after make-up is finished; a plurality of magnets areadopted to attract each other, so that the effects that the adsorption force is stronger and the shell is not easy to slide off are achieved; a wireless charging mode is adopted, so that the effect of convenient charging is achieved; the luminous body is adopted to emit light, so that use at night or in a dark environment is facilitated; the telescopic supporting frame is adopted, the cosmetic mirror is placed in various modes and is more convenient to use, and the supporting frame is hidden in the shell and is convenient to carry.
