What happens to skin after Kybella injections?

Thank you for your question. With any fat contouring procedure, whether it's Kybella, CoolSculpting or liposuction, after reducing the volume of fat the skin will always contract to some degree. The better the quality and elasticity of the skin, the better the amount of contraction. For a 22 year old with your height and weight, unless you have had a large amount of weight loss in the past, I would expect excellent skin quality and optimal contraction of skin around the improved neck contour that should result after Kybella treatments. I recommend that you consult with an experienced, ABMS board certified injector to help determine if Kybella is the best treatment to meet your needs. Best of luck! Dr. Max Polo

Thank you for your question about Kybella.  Your questions are all great!
Kybella does permanently melt the existing fat cells, however you produce new fat cells if there is weight gain.  Kybella is made of deoxycholic acid,  and works by dissolving fat cells.  You will immediately see the effects of this fat dissolving action, as your under chin area will begin to feel very "jiggly" and you will have some slight swelling as this chemical reaction takes place. If your skin has good elasticity it is expected that it will retract after the swelling dissipates.  As for downtime, there really isn't much.  You will typically have swelling in the area for a few days, and it is possible to have slight bruising.  The full effect of the treatment isn't typically evident for about 8-10 weeks, and treatments should be scheduled about 8-10 weeks apart.  
To be sure, see two or more experienced, licensed and board-certified providers in your area for a complete evaluation to make sure you are a good candidate and that it is safe for you to have treatment. I hope this helps.

Thank you for the detailed question. Kybella only works on the fat cells around the area it is injected causing them to die and be gone forever. The skin that is still there can contract naturally if the patient has good skin elasticity. I recommend going in for a consult with a board-certified plastic surgeon to examine you and see if you are a good candidate for Kybella. If after the series of Kybella (usually 3-4 injections about a month a part) treatments you have loose skin, there are lasers that can be used to tighten the skin. Perhaps you and the surgeon will decide that you are a better candidate for laser-assisted liposuction to get rid of the fat and tighten the skin in one procedure.
