I had a small amount of Kybella injected on Friday afternoon. How long will I be red and swollen?

Hello,
Kybella is a deoxycholic acid injection that eliminates unwanted fat under the chin.
Swelling post Kybella procedure is very common. Swelling occurs immediately after injection and can last anywhere from 2 to 4 weeks after the procedure. Other common reactions are numbness to touch, soreness, tingling and bruising. We recommend icing the area to alleviate some swelling and discomfort, Vitamin B complex for nerve regeneration and light massage a few days after the procedure.
In our practice, we also offer complimentary MLD treatment (manual lymphatic drainage massage) a few days after the Kybella treatment. MLD uses light touch to move excess lymph and fluid out of the tissues and back into the lymphatic vessels.  This greatly reduces the amount of swelling that our patients experience.  
 Good Luck.

Unfortunately, swelling is a complication of kybella that can't be avoided.  I have seen swelling last anywhere between 2-4 weeks.  There have been anecdotal reports of kybella being mixed with steroid prior to injection to help alleviate some of the swelling.  In some ways, you want the swelling as it signifies the destruction of fat cells.

Redness and swelling can be typical after Kybella and can take several weeks to resolve. Swelling can be improved with venus legacy and lymphatic massage. It can take 6-8 weeks to start to see results with Kybella. To improve Kybella results, I recommend a combination approach with thermage, ultherapy, exilis. VASER liposuction in combination with ThermiRF is an alternative for contouring the chin, if you're a candidate. I recommend getting a formal evaluation with a cosmetic dermatologist. Best, Dr. Emer

Every patient heals at her own rate, but generally, the swelling, redness and pain resolve within about 2- 4 weeks. Hopefully, you will be on the shorter end of that healing cycle. 

Thank you for your question. Your concern is quite common and during the consultative process you should have been made aware that you could have significant swelling, bruising, redness, numbness and pain. The swelling, bruising and pain usually resolve by the end of two weeks. Numbness can sometimes persist for months.  Keep in mind it usually takes a series of 2 to 4 Kybella treatments spaced 6 to 8 weeks apart to achieve an acceptable result. As an alternative to Kybella, I often suggest the FaceTite procedure from InMode. It is a one time procedure that destroys the fat cells while tightening the skin. We combine this with Venus Legacy treatments to accelerate the healing process. I suggest you consult with your provider and let him know of your concerns. The good news is that your response correlates to cellular death of the fat cells in the treatment area.
