Pixel Perfect works by creating thousands of microscopic perforations, but the skin around each of these perforations remains intact. This allows your skin's top layer to heal from the edge of these tiny holes very rapidly, which significantly improves your complexion. In more detail, the Pixel® laser light passes through patented optics to penetrate the skin with tiny thermal channels, only as deep as a few sheets of paper. In each channel it creates a micro-injury, without disturbing the surrounding tissue. These micro-injury sites (about 15-20 percent of the treatment area) start the process of healing. As collagen remodels, skin tightens and scars improve. The intact, undamaged skin around the treatment site is what promotes quicker healing for a faster recovery.
