Cost varies in the geography of your treatment area. It may be based on area of treatment on the face, or the number of units. Some doctors might use 12 units, others might use 25 to 35 units depending on the mass of the muscles being treated. In some practices, a doctor may delegate the treatment to a nurse or the doctor may do it. If you need more units because your muscle mass demands it, and you didn't have an adequate response, there may be an additional cost. The range in price can be considerable from a couple hundred to several hundred dollars. Don't shop price alone; customer service is an important part of any practice and may be worth spending more so that your concerns are addressed not only at the time of the visit, but after, as well.
