Thank you for your question taylornoellexo. Kybella is the first and thus-far only FDA-approved non-surgical injectable treatment for the double chin. The double chin can be formed by various factors including age, weight gain, and genetics.Although in the pivotal studies treatments were performed at four week intervals, I find that performing treatments at twelve week intervals provides for better results. This may be due to an increased amount of time for healing of the skin, allowing nodules to dissolve and swelling to completely subside. Therefore, I recommend that patients start with one treatment, followed by a second treatment three months later, and return three months after that to assess initial results. At that point, more treatments may be performed if further enhancement is desired. Patience is important.With any injection, there is a risk for pain, bleeding, bruising, redness, tenderness, swelling, and infection, We take special precautions to minimize these risks. We numb the skin prior to the treatment and apply cold air to maximize our patients' comfort. We treat bruises with a laser as early as the next day. Bruises usually resolve by two weeks and after a laser treatment they usually resolve in one to three days, although it still can take up to two weeks for full resolution. Most people feel a burning sensation for about 15 minutes after the treatment. This is addressed by placing cold compresses on the area which we provide in our office.Please consult with a doctor for specific recommendations. Good luck!
