Kybella’s active ingredient is deoxycholic acid. Essentially this active ingredient dissolves small pockets of fat. I find that many patients have a small pocket of this fat in the under chin area that pushes down the skin. After a series of treatments over a few months, this fat pocket is permanently dissolved and provides an excellent contour to the under chin and neck area.It’s noninvasive which means no surgery and can tighten the skin as well. Minimal downtime and great results!
