Would Chin Liposuction Result Be Too Minimal?

Most patients with submental and neck fat will benefit from liposuction.  If you have significant sun damage, you may have loose skin.  But if your skin is resilient, the results are stellar. 

When there is only minimal fat and loose skin on the neck, below the chin, using standard liposuction techniques can cause contour deformities and loose skin after the fat has been removed.

There is also risk of contour deformities using the open technique with direct excision of fat under direct vision, plus the incision required is much larger than the tiny puncture wound used with Laser liposuction.

In my experience, the new Laser Assisted Liposuction using the SlimLipo technique has produced excellent fat removal and skin tightening in young people who have only minimal fat and or loose skin.

The instrumentaion required with SlimLipo is very tiny because the fat is liquefied before removal thus only small cannulas are needed to remove it. In addition, the laser heat generated skin tightening is a significant advantage in my opinion.

Results have been excellent (see photos in link below.)

This can be a difficult result to predict. Generally I tend to simplify and group patients into two types. Those with "double chins" ( a horizontal roll of fat below and behind the chin) or a "turkey neck" (loose vertical bands that hang down from the chin).
Double chins tend to fare better with liposuction and frequently a chin augmentation.
Turkey necks typically require a skin removal and/or muscle repair. Liposuction will generally provide a minimal result without some form of skin/muscle redraping or redistribution with susupension.
It sounds as if you are describing the latter condition.
