Kybella

Most patients describe Kybella as mildly uncomfortable but not overly painful. You may experience a slight stinging or burning sensation during the injection, but topical numbing agents or cold packs can be used to minimize any discomfort. The area may feel tender or swollen for a few days afterward, but this is typically manageable with over-the-counter pain relievers and aftercare instructions.

The number of Kybella appointments varies depending on your anatomy and how much fat is present beneath the chin. Most patients require 2 to 4 treatment sessions spaced at least one month apart. However, some individuals may achieve their desired results after just one or two sessions, while others with fuller profiles may require up to six treatments for optimal contouring.

Kybella results gradually appear as your body breaks down and flushes out the destroyed fat cells. Most patients begin noticing visible changes within 4 to 6 weeks after treatment, with continued improvement over the following months. Once your final session is complete and swelling subsides, the results are permanent, provided you maintain a stable weight.

Yes, and in many cases, combining Kybella with other aesthetic treatments can yield even more refined and balanced results. At Tania Cohen Dermatology, Kybella is often paired with dermal fillers to restore contour and structure along the jawline once under-chin fat is reduced. If you’re also concerned about skin texture or early signs of aging, treatments such as microneedling or laser skin resurfacing can be added to stimulate collagen production and enhance overall skin tone and firmness. Combining procedures enables a more comprehensive rejuvenation and often reduces the need for future surgical intervention.

Like any injectable treatment, Kybella comes with potential side effects—some of which are expected and temporary, while others are less common but more serious. Knowing what to expect is key to a smooth experience and great results.

Common, Expected Side Effects:

• Swelling: The most noticeable side effect, and often the most intense. Swelling can begin immediately after injection and last anywhere from a few days to several weeks. It’s a sign the fat cells are breaking down.
• Bruising and redness: Especially around the injection sites.
• Numbness or tenderness: Some patients experience temporary numbness, tingling, or a “firm” sensation under the chin. These typically resolve within a few weeks.
• Hardness or small lumps: As the body metabolizes the fat, it can sometimes form small, firm nodules that typically resolve on their own.

Less Common but Potentially Serious Risks:

• Nerve injury: If Kybella is injected too close to the marginal mandibular nerve (which controls muscles in the lower face), it can cause temporary facial asymmetry or a crooked smile. This is rare, but it underscores why choosing a skilled injector is crucial.
• Difficulty swallowing: This is also a rare but possible complication if the solution affects nearby structures. It’s usually temporary and resolves without intervention.
• Important Note on Results & Skin Tightness: Kybella does not tighten skin, so patients with skin laxity under the chin may notice increased looseness after fat is removed. This is why a consultation is crucial: your provider can assess whether Kybella is the right approach or if other procedures, such as liposuction, may be a better option.
