Ultherapy - "Gobble" Area Under Chin Looks Worse - Normal (Temporary) Side Effect?

Swelling is common and  can occur with most patients but varies from person to person. Your swelling will peak around 2-3 days then start to lessen.  This is a temporary side effect but you can always follow with your provider for any additional post care recommendations. 

Ulthera uses focused ultrasound to stimulate the collagen-rich layer under the skin, so the collagen remodeling that occurs over a few months after the treatment gives a firming effect. Because there is heat generated at the focal point, there is often some swelling. Also, better collagen to begin with often means better results, so it works  best on patients in their 40's as compared to late 50's or 60's. The neck is a tricky are because the two skin folds that form from the chin toward the chest are related to a muscle called the platysma, not simply skin laxity, so the response to Ulthera is often less ideal there. Most likely in your case the problem you describe would be temporary.

Swelling does occur in many patients.  The Ultherapy works by inducing inflammation which then causes production of new collagen which then helps solidify loose tissues.  The localized swelling can make some tissues look more baggy initially.  Swelling can cause itching and numbness in some patients. Please bring these symptoms to the attention of your doctor. They can examine you and give you reassurance.
