Ultherapy works by using ultrasound energy to safely and effectively stimulate and tighten the deep structural support layers of the skin, including those typically addressed in a surgical facelift. As the skin is stimulated, it tightens and creates a smoother profile, correcting the appearance of a sagging face, “turkey neck,” or décolletage. While results are impressive, Ultherapy is not going to replace a facelift, although it is a perfect treatment for those who aren’t ready to commit to surgery.
