Is laser liposuction an effective treatment for sagging jowls and double chin?

You are asking a terrific question without a simple answer.  If you go somewhere that only offers laser liposuction for jowls and neck then you are going to get laser liposuction.  There are many factors that contribute to double chin and jowling.   A photo would be helpful.  If your expectations are reasonable and your anatomy is favorable then laser liposuction will absolutely tighten your jowls and neck.  If you have fairly advanced jowling as well as laxity of the muscles in the neck along with fat beneath the muscles of the neck then other procedures might be necessary to achieve the results that you are looking for.  A consultation with a skilled facial surgeon will be worth your while.  

We usually use a combination of treatments for a chin and neck lift. Laser liposuction of the chin and neck is a great alternative to a surgical lift. Only tiny incisions are made to introduce the tools and they fade nicely. If done properly, the laser should help to significantly shrink the skin and melt the fat pad (ie turkey neck) and lessen the overall sagging by at least 50%. Careful liposuction of that area will remove the unwanted volume and sculpt the area.
Jowling can be coming from the loss of volume in the cheeks. FIller in the cheeks can help replace the volume loss thereby lifting the cheek tissue and helping to decrease the jowling.

Hi Tim, I find that VASER Hi-Definition Liposuction in combination with ThermiRF, Renuvion and InMode FaceTite is best for contouring the neck and chin in those who are candidates. I recommend getting a formal evaluation with an expert. Best, Dr. Emer

Laser liposuction is an effective way to remove fat from targeted areas of the body, such as the chin and jowls.  Whereas liposuction's main function is removing fat; the addition of the laser to the liposuction procedure gives the added bonus of tightening skin in the treated area so that loose skin is not left behind once the fat has been removed. For someone who has mild skin laxity, laser liposuction may be able to achieve the desired results.  
A consultation with a board-certified surgeon will help you to determine which procedure(s) is best for you so that you can achieve your desired outcome.

Thank you for your question!  Laser Liposuction is an effective treatment for the jowl and double chin.  I recommend that you schedule a consultation with an experienced doctor in order to get the best results.  Best regards!
