The frequency of skin tightening treatments varies based on the area you are treating and the method used. Surgery is a one-time treatment, and non-surgical options such as laser skin tightening or radiofrequency treatments are typically done a few weeks apart. A series of treatments is necessary to allow for collagen production and a gradual tightening of the skin. You may need between six and eight sessions, depending on the area you are treating and the technology used.
