Can Ultherapy plump cheeks?

Ultherapy, which uses microfocused ultrasound energy for noninvasive skin lifting, does not add volume so it would not be expected to plump the cheeks. It can be combined with fillers such as Juvederm if that is what you want.

Ultherapy specifically targets sagging and loose skin mainly in the neck and jowl area. If you are looking to increase volume in your cheeks, you can look into the volumizer Sculptra or dermal fillers like Juvederm or Restylane. These are very effective in plumping the cheeks and filling out hollowed areas.
