Dear Peterrr:Because Ultherapy works at a deeper level than microneedling, I do believe you can have the treatment performed after microneedling and may experience a benefit at all layers of the skin. Ultherapy transducers can delivers cones of intense focused ultrasound at depths or 4.5 mm, 3 mm, and 1.5mm. Since most micropens can go to a depth of 2.5mm at most, I would avoid having the 1.5mm transducer with Ultherapy, as this will only increase your cost without known additional benefit. Be aware that this combination has not been studied in clinical trials.Personally, I would be a bit more conservative and suggest that you wait for at least two weeks if not 4 weeks before Ultherapy, to ensure all undue swelling and inflammation from the microneedling has resolved.All the best,Dr. Clark
