DRS 540 Titanium Needles Derma Roller

The medical dermaroller needles are 0.5-1.5 mm in length. During treatment, the needles pierce the stratum corneum and create microconduits (holes) without damaging the epidermis. It has been shown that rolling with a dermaroller (192 needles, 200 µm length and 70 µm diameter) over an area for 15 times will result in approximately 250 holes cm2 . Microneedling leads to the release of growth factors which stimulate the formation of new collagen (natural collagen) and elastin in the papillary dermis. In addition, new capillaries are formed-this neovascularisation and neocollagenesis following treatment leads to reduction of scars.[4‐6] The procedure is therefore aptly called “percutaneous collagen induction therapy” and has also been used in the treatment of photoageing.
