Thank you for your question and for sharing your photograph ab102. I am sorry to hear about your situation. Kybella is the first and thus-far only FDA-approved non-surgical injectable treatment for the double chin. The double chin can be seen as a result of age, weight gain, or genetics. The one factor that one can control is weight and I advise my patients to maintain a healthy lifestyle by eating a healthy diet and exercising regularly to maintain a healthy weight.It is important to understand the differences between a surgical approach and a non-surgical approach. Almost always a surgical treatment will provide better and longer lasting results than a non-surgical approach. However there are many patients who do not desire surgery and a number of non-surgical alternatives are available. Therefore it is important to have appropriate expectations prior to moving forward with a non-surgical treatment.The primary non-surgical treatments for the double chin are Kybella and Cools Sculpting mini, although new treatments are made available regularly. It has been my observation that patients with mild to moderate fullness get the best results from Kybella and those with severe to extreme fullness get the best results with Cool Sculpting. Often times a series of Cool Sculpting treatments is followed by a series of Kybella treatments for improved results.If Kybella is being performed on its own it is important to understand that multiple treatments are almost always required. The pivotal studies demonstrated that most patients require 2-4 treatments, sometimes up to 6 treatments. Theses studies used 2 vials per treatment and I find that this is a good dose. However some physicians use more or less depending on their preference, experience, and comfort level. Swelling is seen 100% of the time and the more product is used the more swelling can be expected. Some patients see a decreased amount of swelling after a second treatment even when the same dose is used. This may be the body adjusting to the treatment or the fact that there is less fat that is treated. Those with more fullness can expect to undergo more treatments.In the pivotal studies, treatments were performed at four week intervals. However in my experience I have found that waiting three months (12 weeks) allows for more healing of the skin and yields better results. Therefore it is important to understand that the process will be slow.The issue of loose skin comes up a lot when discussing Kybella. When a surgical liposuction is performed the fat is physically removed from the area. In the case of Kybella, on the other hand, the fat is dissolved and slowly removed by the body over time. As this occurs there is an inflammatory reaction that occurs as evidenced by the swelling. This inflammatory reaction possibly leads to the formation of collagen in the area to tighten the overlying skin. This may be the reason why loose skin is not commonly seen after the fat is removed from a series of Kybella treatments.Pricing for all cosmetic treatments varies from office to office.
