Ultherapy almost 4 months out now!!

With any laser or ultrasound treatment, people will respond differently.  Some patients get a great lift and tightening, and some do not.  If a patient has some jowling and neck laxity with fairly thin skin, they will usually get a good response.  Patients with a lot of skin or very heavy necks will not.  In the brow area the treatment is not as heavy as in the neck.  So if you have not tightened at all here they should be able to do another treatment.     

There are times that Ultherapy will be more effective in some areas of the face or neck than others. Ultherapy has a high patient satisfaction rating in my NYC practice but that does not  mean that every patient receives the amount of lifting they were hoping to achieve. There can be no guarantees when a physician treats a patient with a non-invasive or minimally invasive energy-delivering system to effect a lift because the patient's body must respond with an optimal dermal improvement and this is idiosyncratic to the individual. There may be some element of improvement that patients don't realize until they look at their before photographs and see the difference that was achieved because when we live with ourselves every day since the procedure, we don't see the change as dramatically. On the other hand, whether it's with Ultherapy, Pelleve, Thermage and ThermiRF, there may be more improvement obtained when a second procedure is done. The physician has to be concerned about which areas of the forehead are treated and is limited by needing to avoid certain anatomical structures during treatment with Ultherapy. Different physicians may perform the treatment differently and some may deliver more energy/more lines of treatment, and use different applicators to treat different depths of the skin and subcutaneous tissue.If a second procedure is done, many physicians will charge a second fee, although it might not be as high as the first, to offset the very high consumable cost to the physician..This varies from practice to practice and possibly from case to case. The information provided in Dr. Shelton's

Like all  noninvasive treatments, Ulthera uses energy to stimulate a healing response which in turn produces the desired effect. Because of this, there is inherent variation in the response, and as you have noted it can vary from one area of the face to another in addition to different responses by different patients. Older patients tend to respond less well to these treatments because the collagen-building capability is less. We sometimes give a "booster" treatment at about 6 weeks.

I recommend that you look at your 'before and after' pictures and you will be pleasantly surprised to see significant brow lifting with Ultherapy. >85% of patients are very satisfied with Ultherapy for non surgical brow lifting.Read the Ultherapy ebook provided on the link below. 

In most cases, patients can expect to see the full benefits of an Ultherapy treatment in about two to three months and they can expect for the results to last about a year. Although Ultherapy can vary from patient to patient, if you haven't seen any results within four months, I would schedule a follow-up appointment with your doctor to express your concerns.
