Dr. Xu's Real Double Chin Treatment Cases
The following four cases were personally assessed and treatment-planned by Dr. Dan Xu at our Toronto Markham clinic, and are shared with patient authorization via signed Media Release Forms. The causes of submental fullness are multifactorial — including excess fat, skin laxity, platysmal banding, and skeletal retrusion — and results vary significantly between individuals. Outcomes should be assessed through an in-person consultation.
