Ultherapy can definitely help raise the forehead, which in turn, raises the eyebrows, and then the upper eyelids using deep focused ultrasound without surgery. The amount of improvement, however, is not expected to be the same good result as with a surgical brow lift. the Ultherapy can make patients happy without going through surgery and minimizing the down time. There are risks with all treatments so discuss them with your doctor. Some of these risks include numbness of the forehead or scalp but it may be temporary. Downtime is usually considered to be negligible with Utlherapy, but the forehead can cause swelling which can deposit itself around the eyelids and can take a few days to go away.
I have found that injecting the forehead with local anesthetic, which is an off-label protocol, helps make it much more of a comfortable procedure, allows me to use transducers that would have been too deep without the increased thickness of the tissues resulting from the local anesthetic, and gives my patients more of a lift. This however, can increase the downtime as the local anesthetic injections can cause bruising and the volume of liquid anesthetic can deposit itself around the eyelids a day or more after the procedure as gravity pulls the fluids down.
