One important difference between Ultherapy and Thermage is the method they use to stimulate collagen production, states Z Center for Cosmetic Health. Ultherapy involves ultrasound, while Thermage tightens skin with radio frequency technology. Thermage addresses the upper layers of the skin. Ultherapy handles those, as well as deeper tissue.
Thermage stimulates collagen in comparatively large sections of skin, Z Center continues. The ultrasound technology used in Ultherapy directs heat energy to specific areas. If practitioners do not perform Thermage properly, burned skin is possible. Because the practitioner is able to control the trajectory of ultrasound better, injury is less common. Of the two procedures, the FDA approved Ultherapy for tightening and lifting the muscles and skin of the face and neck.
When dealing with the eye area, Ultherapy results typically resembles cosmetic surgery, proposes Nowak Aesthetics. Ultherapy effectively deals with sagging skin surrounding eyes. Thermage works well for eye wrinkles such as crow's feet. This process is also appropriate for the undereye area. Ultherapy is useful for the outer eye areas.
Ultratherapy is typically done when patients are numb, according to the Lasky Aesthetics & Laser Center. Numbing is not used with Thermage because the practitioner monitors patient discomfort level and adjusts treatment accordingly.
