Microneedling, also called collagen induction therapy, percutaneous collagen induction, involves the use of many small needles to puncture the skin. This creates a micro-injury and the body’s natural healing properties then begin to repair this injury with increase collagen and elastin production resulting in improvements in skin texture and resiliency.
After cleansing the skin surface and applying topical anesthetic, the microneedling device of choice (often a rolling or pen-like system) is then utilized to create the injuries. The nondominant hand is used to smooth and stabilize the skin while the opposite hand treats all desired areas of the skin over the course of approximately 20-45 minutes. The endpoint is pinpoint bleeding. Although it can be on its own, it is now often to use this technique to aid with transdermal delivery of other therapeutic medications. The devices may vary, but the size of the needle is typically 0.1-0.25mm in diameter. The mechanism of action involved with microneedling creates micro-injuries which leads to a release of growth factors and triggers the wound healing cascade. The needles also aid in mechanically breaking down the scar tissue. Neovascularization and neocollagenesis is triggered. The end result is aesthetically pleasing, yet without a significant recovery time because the epidermis is not destroyed.
The goal of a microneedling procedure is to target imperfections of the skin with micro-injuries which cause the release of growth factors and triggers the wound healing process which produces collagen, creating younger looking skin.
