Kybella for Fat Under Chin – What are the side effects?

The marketing, of course, makes it sounds like there aren’t any!
The main side effect is swelling at the site.  The company protocols advise a first treatment with approximately 2 vials.   At a recent conference, many of the doctors who were involved in the trials were saying privately that they recommend starting with one vial, even though it slows the response slightly.  Reasons –  many patients will be understandably angry if the swelling makes them look like a bullfrog for a week or two.   We all need to be able to function.
By the second treatment, using 2 vials makes sense because there’s less fat now to become inflamed.   The end result is still the same.   All had some mild redness and soreness.   The couple of cases of nerve damage were temporary and related to the injector injecting into the wrong area.

One of the best investments in your skin is your daily skincare. Why? Because you can prevent many problems with blotchy skin color, lack of glow, texture, some types of acne, and fine lines with good skincare products. You can also correct some of these problems with effective skincare products. Great skincare is often more expensive because quality ingredients are expensive. Some companies spend on research/development which benefits all of us and adds to the cost. Are they worth it? In general - yes! I have handpicked some of what I consider to be the best skin care products, and offer them for sale on SkinTour's shop. This is based on my team and I's testing and research at our clinic. Many of the products are in my own regimen. What could be better than using skin care products a dermatologist uses?!
