With just one treatment, the regenerative process is initiated, but the full effect will build gradually over the course of two to three months. Some patients may benefit from more than one treatment. Visible effects include a lifting and toning of loose skin. In the FDA clinical trial for instance, nine out of ten patients had a noticeable, significant lift of the brow line. This resulted in reduced skin laxity on the eyelid and a more open, youthful look to the eyes overall. Patients reported firmer, better-fitting skin in other areas of the face and neck as well. There is also an invisible result from the procedure with the creation of new collagen, which gives the skin its youthfulness.
