Ulthera is now registered in Mexico to market and distribute its ultrasound therapy device, the Ulthera System. In Mexico, the system is now prescribed to produce stimulation in tissues to raise the temperature in a localized manner for aesthetic, non-invasive use, according to the company. The Ultherapy procedure encourages the natural formation of collagen and elastin in the skin, giving it the ability to lift tissue. In Mexico, the technology will be used specifically to lift tissue on the face, neck, décolleté, knees and arms.
