Although the mechanism of action with the Dermaroller is not totally explored, nevertheless the results for the improvement of skin structure and scars, especially acne scars, in over thousands cases speak a clear language. The procedure with the Dermaroller became standard expressions in scientific literature with the terms COLLAGEN INDUCTION TREATMENT and MICRO-NEEDLING.
DERMAROLLER: A drum shaped roller stud with 192 fine micro-needles from 0.5 to 1.5 mm in length and 0.1 mm in diameter penetrate the dermis repeatedly for about 20 times. The skin cells react to these micro injuries and stimulation with the release of various growth factors. These in return stimulate the proliferation of undifferentiated cells and this reproduction results in NEO-COLLAGENESIS and NEO-ANGIOGENESIS. New tissue structures are generated in forms of elastin- and collagen fibers as well as new capillaries. They integrate into the existing upper dermal layer without any fibrotic traces.
