Kybella Injection

Kybella has been approved by the FDA as a safe and highly effective treatment for submental fullness (also known as a double chin). However, Kybella does carry risks similar to all minimally-invasive injectable treatments. The most common risks include dimpling, irregularities, depressions, and temporary nerve damage. Kybella and other injectable treatments can, in rare cases, cause more serious risks such as permanent damage to facial structures and nerves, as well as damage to organs such as the thyroid and parotid. We recommend that Kybella treatments only be performed by a highly experienced Board Certified plastic surgeon to minimize, as much as possible, the potential for serious risks and side effects.

What to Expect After Kybella Injections

Bruising, swelling and mild discomfort can be expected following your Kybella treatment. These issues should resolve within 72 hours. You will be asked to avoid exercising during this time and to take it easy in general. This is just a precautionary measure to reduce overall bruising and swelling. We like to recommend anti-inflammatory medications and localized ice with a chin strap the first few days after the treatment. Since the area tends to be sensitve, massage is not ordinarily recommended.

A skillfully trained provide will lessen any risks of uneven or inadequate injection details to minimize any risk of lumpiness or uneven texture.

Side Effects of Kybella

One of the main side effects of Kybella is irritating the nerve in the area to be injected.  This is why patient anatomy and careful marking before injections is key to the proper injecting of Kybella. You have to inject Kybella only in the submental area. It is really important to consult a board certified dermatologist who has been trained in Kybella for the best cosmetic results.  I often combine Thermage for skin tightening with Kybella to achieve the best results for the lower neck and jowls.  Best, Dr. Green

Risks of Kybella injection

The main risks of Kybella injection depend mostly on the skill, training and experience of the injector as well as the product. It is best to be injected by an expert such as those training for the company. Our office is involved with training other doctors and we have seen good results with no complications. The main issues to be aware of if injected improperly are temporary nerve dysfunction of the nerves that control the lower lip, and possible skin ulceration if injected too close to the skin. Other normal side effects are temporary bruising and swelling and temporary mild numbness in the area injected. Overall extremely safe in expert hands.

Kybella injections are FDA-approved as both safe and highly effective for the treatment of submental fullness. However, Kybella is an injectable treatment, and carries risks similar to other injectable treatments. The most common risks are dimpling, irregularities, depressions, and temporary nerve damage. More serious but much less common risks include permanent damage to facial structures and nerves, as well as damage to organs such as the thyroid and parotid. We recommend that your Kybella injections be performed by a highly experienced Board Certified plastic surgeon to minimize the potential for serious risks.

Kybella risks

It is important to always find a certified and experienced injector, especially when dealing with areas of high risk, like your face and neck.  Kybella does cause a reaction that gets rid of fat and can affect the surround tissues.  Some of the side effects include skin ulceration, bruising, swelling, and dysfunction of the nerve that causes your lip to lower.  These risks are all lowered with proper technique and training of the drug and anatomy and we have had good results and experiences to date.

Kybella - Importance of a skilled and careful injector

You are correct to be concerned.

With any injection, there is a risk of
 1) infection
 2) uneven or poor result

With Kybella, in particular, there is a risk of
 1) nerve injury, particularly to the marginal mandibular nerve.  This would result in an uneven smile.  In the studies, this side effect resolved in all cases.
 2) difficulty swallowing.  Kybella should not be used in patients with a history of difficulty swallowing.
