Hi there! This is a great question. At 5 months post Ultherapy, most results should be visible by now although collagen stimulation and skin tightening can still continue to develop over the next 6 months. Ultherapy is extremely user dependent, but marionette lines are very multifactorial as well. To achieve a reduction in the appearance of the marionette lines, Sculptra and hylaruonic acid fillers for a full-facial balancing treatment should help to achieve your goals, paired with RF microneedling for some additional skin tightening. As always, an in-depth, in-person consultation is required to best assess your anatomy and skin, and come up with the best plan for you personally. Sincerely,Eleni Sgantzos, PA-CViva Eve
