DTS MG created the "Disk Needle Roller" system - a circular disk of a drum is formed by integrating a metal disk having a group of needles. When pricking the skin with the disk needles, the needles do not cause severe damage to the skin and can be prevented from being broken. The circular disks and the retainers of the drum have respective simple structures. With a very dense positioning of needles, GENOSYS Roller can create much more microchannels on the skin comparing to conventional rollers.
Shape of Needle
The drum is configured to form a polygonal cross-section of six sides instead of a circular cross-section. When pricking the skin with the needles, the contact surface of each needle relative to the skin can be reduced, thus minimizing the pain.
Number of needles
GENOSYS Roller has 540 needles for 0.25mm (facial standard model), 450 needles for 0.5 and 1.0mm, and 405 needles for 1.5 and 2mm (facial models), while other rollers have approximately 200 needles. With this feature. With rolling for 10 minutes using 0.25mm standard width, about 500,000 microchannels are created.
