The question of if and how much laser liposuction tightens skin remains to be answered, but a study recently published in a leading journal provides some data. It showed that laser liposuction of the neck tightened the loose skin by about 40%.
In this study, twelve patients who had both excessive fat under their chin and loose skin of their neck were treated using laser liposuction. All patients got nice improvement.
What this study didn’t do was compare liposuction to laser liposuction, and my experience is that liposuction of the chin alone can tighten skin, too. However, this study does show nice results with the method used and provides us with a sense of how much improvement a patient can expect to get with laser liposuction of the chin if they have loose skin of the neck, too.
