Derma rollers are used for a treatment process called micro-needling or skin needling. It is a form of collagen induction therapy.
The actual derma roller is made up of a small, solid wheel attached to a little stick that propels it backward and forwards across your face in small sections. The roller is covered with hundreds of minuscule ‘micro medical needles that penetrate the skin, creating lots of tiny micro-injuries.
Your skin responds by producing extra collagen to ‘heal’ the punctures, and that’s what plumps up the skin again and enhances the natural blood supply – so you get a natural ‘glow’. Depressed acne scars, wrinkles, skin texture and tightness are all improved as a result.
