Does Kybella cause sagging skin?

If kibella is used to destroy submental fat, what happens to the skin? After loss of submental volume, does the skin become sagging? If it doesn't, what makes Kybella tighten the skin after the fat dissolves? Thanks

Will Kybella Cause Turkey Waddle?

Kybella is an excellent injectable for reduction of submental fat. It destroys fat cells and as it does so, it creates an inflammatory response. That inflammation causes the area to swell for several days, which is inconvenient, but it also causes the skin in that area to tighten up. How much fat destruction and how much skin retraction happens with each Kybella treatment will depend on the individual patient, but I have seen great results in my clinic. The key to getting retraction is the presence of some fat. If the area under the chin is all skin, then I would hesitate on recommending Kybella. If you are thinking about Kybella treatment, you have to know that it takes more than one session. Some patients are done after two but some need three to get the desired result. Treatments are spaced about 6 weeks apart.
Hope that helps!

Kybella and skin retraction

Thanks for the question.  Kybella helps to reduce fat under the chin by targeting the fat cell.  This process causes some inflammation which can help to give some tightening of the skin.  It's not as good as a facelift and the amount of skin tightening varies from patient to patient, but most patients seem to be pleased with the results. To put it in perspective, other methods of non surgical skin tightening also have results which vary considerably from patient to patient.  So discuss this with your plastic surgeon to see which treatment may be best for you

Will Kybella cause my skin to sag?

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}
Although Kybella is touted to dissolve fat, this is not its only benefit.  The injections will dissolve local fat but, in doing so, will also produce a local inflammatory reaction which will then in turn help tighten the skin locally.  We have seen that with liposuction of the neck where we remove very little fat volume but often achieve a great deal of skin tightening.  

And so unless your skin has a significant amount of laxity to begin with or you are looking to dissolve a significant amount of fat, the area should tighten up for a period of a few months leaving you with a more refined chin and jawline. 

I hope that helps and wish you the very best!

Kybella and Skin Retraction

Thank you for you question. Kybella can help retract the skin after fat reduction in those with good skin elasticity. If there is moderate to severe laxity present then other tissue tightening treatments or a surgical option may be appropriate. I would recommend an in person exam to determine candidacy.

Kybella & Sagging Skin

You bring up an excellent point. Kybella is ideal for those patients who still have a lot of skin elasticity. Because the procedure causes inflammation, there is a bit of skin tightening, but for patients with very lax skin in the chin/neck area, it can make the situation worse. The only option for lifting loose skin is surgery such as a neck or facelift. Hope this helps.

Sub-mental Skin After Kybella

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

I think this is a great question and is a conversation and assessment that needs to be had between each provider and their specific patient. Kybella's intended use is not for skin tightening, it is for the destruction of adipose cells in the sub-mental area. With that being said, there have been reports of people stating that their skin in that area did become tighter and less lax. The severity of skin laxity definitely needs to be taken into consideration. Minimal laxity may be able to be improved with kybella. However, being left with a "turkey neck" is possible if the amount of skin laxity is significant. I suggest having a very transparent conversation/assessment between patient and provider in order to determine the best route of removing the tissue in that area and to determine whether it is more of a fat issue or skin laxity issue.

Sagging skin after Kybella

If you have good skin tone, it should retract quite nicely after undergoing the Kybella treatments. It is only in the patients that excess skin laxity is not noted prior to treatments that will have the problem of sagging skin. Make sure you go to an experienced injector for an evaluation.

Kybella does not cause sagging skin

Nature abhors a vacuum.  Clinical studies show that the injection causes inflammation which in turn stimulates the production of new collagen.  A pleasant side effect of the Belkyra Treatment may be some tightening of the skin at the injection site.

This is a great question that many people ask. You are correct, Kybella will dissolve the fat in the double chin. It does not directly tighten the skin on its own. So it would seem correct to assume that you may have loose or sagging skin after a Kybella treatment. However, when we look at the published before and after pictures as well as ours from our patients we do not see loose skin after a Kybella treatment. When the Kybella itself is dissolving the fat, an inflammatory reaction in the skin occurs. This inflammation likely stimulates collagen production which tightens the overlying skin. This is something that would be interesting to address in further studies. There are a number of non-surgical skin tightening treatments available for the double chin including cryolipolysis (Cool Sculpting), ultrasound (Ultherapy), laser skin tightening, and a variety of radiofrequency devices.

Kybella is a great injection to permanently reduce the fat under the chin. One of the great benefits of Kybella is that it also tightens the skin under the neck as well.  I often combine Kybella with Thermage for the best cosmetic skin tightening results.  Please consult an expert.  Best, Dr. Green
