Sterile and single use heads, composed by 540 micro-needles in stainless steel. The Needleroll540 head, with its 540 microneedles, allows to cover a greater area of penetration in less time and ability to generate 1.000 micro-channels per square cm in 10 minutes, substantially increasing the effectiveness of the procedure. Stainless steel has been scientifically proven to be the gold standard for tools used for skin penetration. Both Needling Recharges and Needleroll540 heads can be used with Motion device or with the apposite Needle Roll handle.Needling Recharges have the same angle of incidence of hypodermic needles, while Needleroll540 have a diamond shape.
