How effective is Ultherapy for baggy eyelids (brow lift) & crows feet?

Thanks for your question. Ultherapy is designed explicitly for nonsurgical skin tightening. This device uses targeted ultrasound energy to improve skin at the cellular level without damaging the outer dermis or surrounding tissue. We use Ultherapy for patients wanting to refresh and rejuvenate the eye and brow area with great success. You can also combine Ultherapy treatments with injectables like Botox to further enhance your results. I recommend you schedule an appointment with a board-certified dermatologist that specializes in these skin rejuvenation techniques for a personal assessment and a customized treatment plan.

Ultherapy® is the only FDA-cleared, non-invasive procedure that lifts and tightens the neck, chin and brow. It can also help with crows feet, though you may also need/want Botox/Xeomin. Ultherapy uses time-tested ultrasound energy to lift and tighten the skin naturally—without surgery or downtime. Ultherapy has one of the highest satisfaction ratings on realself; 79% WORTH IT compared to Thermage 45%! Try the Ultherapy Simulator to see what results you might achieve. Thanks, Dr Dieffenbach

Ultherapy is preventative and does very little to see active lift, sometimes a small amount on the neck and eyes.  It will not help your wrinkles, that needs botox, lasers, peels and micro needling.

thermage radiofrequency

Ultherapy can help lift the brows and soften crow's feet lines. We use it in combination with other treatments as on it's own it's not the best treatment for the area. Our ThermiSmooth radiofrequency treatment works better in the brow and crow's feet area. Of course, Botox is the best treatment for the crow's feet as it will weaken the muscle that is responsible for the wrinkles. Make sure you see an experienced physician for an in-person consultation and evaluation to determine which treatments are best for you. 

Any single session of Ultherapy® can lift sagging eyelids and tissue around the eyes 30-50%. Results typically last 3-6 months. Costs range widely depending on geography and operator expertise.
