A micro-needle roller is provided to be penetrated into the corium layer of a skin to make cells treat the wound naturally, and to increase the effects of increasing beauty by restricting the skin stress. A micro-needle roller includes plural circular plates(200), a shaft pin(400), a handle portion(100) and a low frequency generation portion(500). A penetrating hole is formed inside the circular plate. Plural needles(300) protrude from the circular plate. The shaft pin is rotatably coupled to the penetrating hole of the circular plate. The handle portion has a support portion. The shaft pin is restricted by the support portion which is formed to make the circular plates rotate based on the shaft pin. The low frequency generation portion is installed on the inner side of the handle portion. |
