There are a bunch of treatment options out there but the Jowls are a hard place to get a good treatment. For an easy and noninvasive treatment look into the INMODE Evoke, no downtime and a quick and easy process.
Noninvasive devices, kybella, even liposuction dont often work for lipomas. most need to be removed surgically. I suggest you see an expert. Best, Dr. Emer.
TruSculpt ID is a safe treatment for clients with a copper IUD in place. The heat will not radiate down as far as the uterus, but will reside in the fat pad area.
