Dermarolling is also known as micro-needling, skin rolling or collagen induction therapy (CIT). Derma Rollers are made of many high grade micro needles which roll over and penetrate the skins upper surface painlessly. These revolutionary devices provide two major benefits.
Firstly, they stimulate collagen growth which significantly improves the appearance of scars, fine lines, wrinkles, stretch mark, and acne scars.
