Dermaroller Studies


Percutaneous collagen induction" (PCI) or "collagen induction therapy" (CIT) is a skin treatment in which the outer layers of the skin, epidermis and dermis, are punctured in a minimally invasive way, thus activating the body's own repair process and the renewal of damaged skin tissue by increasing collagen production. With CIT, wound healing mechanisms are activated without damaging the epidermis; the puncture channels close again quickly.
