3 weeks post op Kybella still don't see improvement & have ice pack burn. I have a lump has decreased. Does that go away?(photo)

You should not expect to see a lot of improvement in three weeks. The swelling can last for at least 6 weeks. The results will take longer than 6 weeks to be evident.
The lump should eventually go away if it is progressively getting smaller, however if it persists you might want to contact the Dr that did the procedure so he or she can evaluate you.

Swelling can last many weeks after a Kybella treatment. In some cases, there can be lumpiness and stiffness that can last several months, but this is less common. Most patients are not going to see any significant improvement after the first injection, and will require anywhere from 2-4 injections to see results. Also, the treatment effect is really not even starting to be visible until ALL the swelling is gone. Then the patient should see progressive tightening of the area over time.Be sure to see an expert physician injector.All the best,

Thank you for your question about Kybella.  Kybella is made of deoxycholic acid,  and works by dissolving fat cells.  You will immediately see the effects of this fat dissolving action, as your under chin area will begin to feel very "jiggly" and you will have some slight swelling as this chemical reaction takes place.  Swelling can be more pronounced depending on bruising.  As for downtime, there really isn't much.  You will typically have swelling in the area for several days, and it is possible to have slight bruising.  The full effect of the treatment isn't typically evident for about 8-10 weeks, and treatments should be scheduled about 8-10 weeks apart.  
To be sure, see two or more experienced, licensed and board-certified providers in your area for a complete evaluation to make sure you are a good candidate and that it is safe for you to have treatment. I hope this helps.

Bruising, redness, swelling, firmness may occur and take approximately 4 weeks to resolve. We typically advise patients to avoid blood thinners a week prior to injection to minimize risks of bruising. We also recommend patients sleep with the head elevated, limit salt intake, and ice for the first 48 hours to minimize swelling. Most patients require 2-6 Kybella treatments spaced 6 weeks apart. The effects of fat destruction occur within days. Typically 4 months after treatment the results are most visible. 

Patients can experience swelling and redness after Kybella for several days after the injection. Patients will experience an improvement in their profile with permanent fat reduction after three to four treatments. I emphasize to patients to allow the product to work and the results have been amazing
