Focused ultrasonic energy delivers precise heating of dermal tissue by direct visualization of all skin layers and non-invasively lifts the deepest layers of the skin by stimulating new collagen synthesis. Since its introduction in 2011, focused ultrasonic rejuvenation of the face can provide non-surgical face lift without any downtime. Focused sound waves will selectively heat up chosen treatment depth up to 70 degrees C. which completely obliterates loose elastin, fibrin, or collagen of old skin and stimulates new production of collagen, giving the treated skin a natural lift over 2-3 months after the procedure. It is the only energy-based device which can safely treat the deepest part of skin for lifting and tightening while bypassing the surface of skin and thus avoiding complications of superficial burns associated with some laser treatments. Focused ultrasonic rejuvenation safely and naturally tightens and lifts skin on the face and neck over time via neocollagenesis.
