It is a form of collagen induction therapy and is also known as micro-needling or skin needling.. The roller is covered with hundreds of micro-medical needles that penetrate the skin, creating lots of tiny injuries. Your skin then produces extra collagen to heal the injuries and that’s what rejuvenates up the skin again.
It also enhances the blood supply to give a glow on face. Pitted scars, open pores, wrinkles, skin texture and tightness are all improved as a result. Microneedling can be painful, given the repeated pricking of your skin so doctors use local anesthetic. It may take a week for the skin to recover because of the swelling.
