The Derma Roller received an 85 percent grade from RealSelf.com. The grade was the result of 50 reviews over 24 months. Reviewers found the Derma Roller helpful in the treatment of shallow scars and facial lines, but some reviewers commented that it was too painful.
Others noted a gradual improvement in the appearance of their skin over time and that a key factor in using the Derma Roller is patience and consistency. One reviewer noticed improvement in the look of stretch marks. Another posted photos to illustrate a noticeable improvement in skin tone and the reduction of pore size.
Derma Roller is a brand name for hand-held devices used for micro needling or collagen induction. The concept behind the roller is that rolling over the skin with needles helps to stimulate the production of collagen. The process can be painful, with some doctors using sedation. Recovery from post-treatment swelling can take as long as one week.
