After a light local anaesthetic (e.g. with numbing cream), the dermaroller is rolled over the skin lengthwise, crosswise and diagonally multiple times. This stimulates the skin by creating many tiny punctures and triggering its repair function. After treatment with the medical dermaroller, the skin forms both collagen fibres (which firm the skin) and elastin fibres (which give the skin elasticity). As a result, scars and wrinkles are filled and smoothed from the inside out. In addition, the dermaroller’s microneedles loosen old skin flakes, deposits and blockages on the top skin layer of the epidermis. This improves the appearance of the skin by making it fresher and more transparent. Skin impurities and large pores are visibly reduced. Finally, medical needling can be combined with mesotherapy. Active ingredients are introduced through the small channels in the skin created by microneedling, making it appear fresher and more vital.
