Ultherapy can be done to the lower face despite a chin implant
As the normal facial treatment of Ultherapy for facial lifting spares the chin, there is no reason to avoid having Ultherapy because of a chin implant. With the new 1.5mm transducer, the chin can be treated as it is more superficial energy than the 3 and 4.5mm deep transducers. The 1.5 mm transducer could safely be done on top of the chin implant as the implant is deeper. You should, however, ask permission from your plastic surgeon who inserted the implant before you undergo Ultherapy.
