Abstract: The present invention relates to a disk needle roller (100) for forming micro-holes in a surface of skin by using micro-needles (220) to stimulate and assist regeneration of the skin. The disk needle roller (100) includes a handle (110) having one pair of supporting bars (120) extended therefrom, and a roller (200) including a plurality of circular spacers (232, 233) placed on a rotation shaft (130) having opposite ends supported on the supporting bars (120) of the handle (110), a plurality of circular disks (210) each between adjacent circular spacers (232, 233) so that the circular disks (210) are rotatable around the rotation shaft (130) independent from one another, a plurality of needles (220) projected from an outside circumference of each of the disks (210) in a radial direction, each with a tip formed sharply for forming micro-holes in skin of a human body.
