Microneedling therapy, also known as collagen induction therapy, is a recent addition to the treatment armamentarium for managing post-acne scars. The treatment is performed as an office procedure after application of a local anesthetic cream, by means of an instrument known as a dermaroller. A dermaroller is a simple, hand-held instrument consisting of a handle with a cylinder studded all around with fine, stainless steel needles 0.5 to 2 mm in length. This needle-studded cylinder is rolled on the skin in multiple directions to achieve a therapeutic benefit and hence the name ‘dermaroller’. These needles cause small pinpoint injuries on the treated skin, which apparently heal within two to three days with no post-treatment sequelae. Treatment with dermaroller is performed at four to eight week intervals and multiple sittings are needed to achieve the desired effect on the skin. Microneedling or dermaroller treatment is becoming popular all over the world, not only in the management of post-acne scars but also as an anti-aging therapy. There are certain advantages with dermaroller or microneedling therapy over laser resurfacing; former does not lead to any epidermal injury as is seen with lasers, there is minimal downtime associated with the procedure unlike ablative laser resurfacing and the treatment is far cheaper as compared to lasers. The treatment can be performed in an office setting and does not need any extensive special training or expensive instruments.
Here at Mattos Institute we firmly believe that microneedling therapy is a simple and effective treatment option for the management of atrophic facial scars.
