High-Intensity Focused Ultrasound (HIFU) is a modality used treat a variety of medical conditions and should not be confused with specific ultrasound-based devices used in facial aesthetics. To date, Ultherapy is the only non-invasive procedure FDA-cleared to lift skin on the neck, under the chin, and on the eyebrow. It is also now FDA-cleared to improve the appearance of lines and wrinkles on the décolletage. This ultrasound-based device tightens the facial tissues through thermal energy. The thermal energy heats up the tissues beneath the skin, which stimulates collagen production and subsequent tightening. However, it is important to consider that the results of non-surgical facial rejuvenation will never be as effective as surgical rejuvenation such as a facelift or eyelid surgery. It is also important to note that ultrasound-based devices will not produce filling. Patients with mild signs of facial aging that want mild improvement or maintenance and minimal downtime are typically good candidates for non-surgical rejuvenation such as ultrasound-based devices and fillers. Patients with severe facial aging are best treated with surgery such as a facelift or blepharoplasty (eyelid surgery). These are also often combined with facial fat grafting; fat is your body's own natural permanent filler with an unlimited supply. View before-and-after photos of both surgical and non-surgical facial rejuvenation in patients who have similar facial aging to you in order to evaluate which will produce the results you are seeking. I would recommend a consultation with a plastic surgeon well-versed in facelift and eyelid surgery who also offers non-surgical rejuvenation to make more specific recommendation to achieve the natural look you desire.
