What is Kybella™?
Kybella™ is deoxycholic acid. It is the first and only FDA approved injectable drug that contours and improves the appearance of submental fullness or “double chin.” It is also used “off label” to decrease jowl fat and define the jawline. It is synthetic but identical to a fat dissolving product made by our gall bladder to help break down fat. Kybella™ is not a treatment for lax or excess skin, vertical bands or horizontal lines on the neck or for jowls.
When will I see results?
It takes a minimum of 2 treatments to appreciate any results. Most patients will achieve their desired results within 3 months after their 3rd or 4th treatment though up to 6 treatments may be administered. Treatments are performed 4 to 8 weeks apart. It is possible that you will not see improvement despite multiple treatments due to your underlying anatomy, skin tone or other factors.
When will I see results?
It takes a minimum of 2 treatments to appreciate any results. Most patients will achieve their desired results within 3 months after their 3rd or 4th treatment though up to 6 treatments may be administered. Treatments are performed about 8 weeks apart. It is possible that you will not see improvement despite multiple treatments due to your underlying anatomy, skin tone or other factors.
How long will the results last?
The improvement in the submental area is very long lasting and the need for retreatment is not expected. Normal aging changes in the skin and other tissues of the neck will continue to occur however. Though the treated fat cells are destroyed and replaced by collagen, a small amount is left behind. If you gain a great deal of weight, the remaining fat cells may expand giving a full appearance.
What are the most common side effects?
All patients should expect swelling in the treated area. This is most dramatic in the first 3 days after the first procedure. Subsequent treatments generally result in significantly less swelling. Swelling will steadily decrease but may still be noticeable at a month post treatment. Tenderness, discomfort and numbness in the treated area is very common and can last weeks. Redness and firmness in the area is also common. Bruising is possible and will generally resolve in a week.
What are less common adverse reactions?
Difficulty swallowing can occur generally lasting for a few days post treatment and is thought to be due to swelling of the area. A “pins and needles” sensation, itching, skin tightness, headache, nausea, discoloration of the skin, swollen glands, hives in the area, and neck or throat pain, ulceration of small areas of the skin have also been reported. An uncommon side effect is temporary injury to the marginal mandibular nerve resulting in an asymmetrical smile lasting an average of 6 weeks. No cases of this side effect were permanent. In the beard area of men injections could cause small patches of hair loss in the treatment area.
