Kybella is $799 per vial at InjectCo. Your total cost is the number of vials per session times the number of sessions. The FDA label allows up to 10 mL, or five 2 mL vials, per treatment, and up to 6 treatments spaced at least 1 month apart. Your nurse injector sets your plan at consultation.

Kybella is priced per vial, so a session’s cost depends on how many vials your treatment area needs. Each vial holds 2 mL, and the label allows up to 10 mL in a single treatment.
| Vials in one session | Cost at $799 per vial |
|---|---|
| 1 | $799 |
| 2 | $1,598 |
| 3 | $2,397 |
| 4 | $3,196 |
| 5 (label maximum per treatment) | $3,995 |
Your total is the cost per session added across your sessions. For example, 2 vials in each of 2 sessions is $3,196, and 3 vials in each of 3 sessions is $7,191. These are arithmetic examples, not treatment plans.
The prescribing information also says each vial is for a single patient and any unused solution is discarded. Ask your nurse injector how a partly used vial is counted in your quote.
What the FDA label says
The clinical trials behind the label give a sense of how this plays out. People received up to 6 treatments, and 59 percent received all six. On average, they received 6.4 mL at the first session, a little over three vials’ worth. Those who completed all six received an average of 4.4 mL at the sixth, so later sessions often use less product as fat decreases.
In the REFINE-2 phase 3 trial, 66.5 percent of people treated with Kybella improved by at least one grade on both clinician and patient ratings, compared with 22.2 percent on placebo. Results were measured 12 weeks after the last treatment.

Health insurance doesn’t cover Kybella. Reducing fat under the chin to improve appearance is a cosmetic treatment, so you pay for each vial out of pocket.
HSA and FSA rules follow the IRS definition of a medical expense. IRS Publication 502 excludes cosmetic procedures, which it describes as procedures directed at improving appearance that don’t meaningfully promote the body’s proper function or prevent or treat illness or disease. Kybella for a double chin fits that description, so it generally isn’t eligible. If you think your situation is different, check with your plan administrator before treatment. Our guide to using HSA or FSA for Kybella covers the details.
The two approaches differ more in how treatment is delivered than in what they aim to do:

Most side effects in the label’s pooled trials were at the injection site. Swelling affected 87 percent of people, bruising 72 percent, pain 70 percent, and numbness 66 percent. Some lasted longer than a month, including numbness in 42 percent and swelling in 20 percent.

Kybella destroys the membranes of fat cells in the treated area, according to its label. The longest-term evidence on how long results last comes from a 3-year follow-up of the REFINE trials. The study enrolled 224 people who had improved at least one grade.
Among those treated with Kybella, the improvement was maintained in 86.4 percent at year one, 90.6 percent at year two, and 82.4 percent at year three. About three-quarters of the patients who were satisfied at 12 weeks were still satisfied at year three, and no new treatment-related side effects were reported.
Kybella is $799 per vial at InjectCo. Each vial holds 2 mL and is single-use.
It depends on the size of the treatment area. The label allows up to 10 mL, or five vials, per treatment. In clinical trials, people received an average of 6.4 mL at the first session, a little over three vials’ worth.
The label allows up to 6 treatments, at least 1 month apart, tailored to your fat distribution and goals. In the trials, 59 percent of people received all six. Your nurse injector sets your plan at consultation.
No. Reducing fat under the chin is a cosmetic treatment, so health insurance doesn’t cover it.
Generally not. IRS Publication 502 excludes cosmetic procedures, and HSA and FSA eligibility follows that rule. Check with your plan administrator if your situation is different.
It depends on how many vials and sessions you need. Kybella is billed per vial at each session, while liposuction is usually quoted as one surgical procedure. Compare full quotes for both before deciding.
In a 3-year follow-up of the REFINE trials, 82.4 percent of people who responded to Kybella still had their improvement at year three.
Kybella is $799 per vial at InjectCo, and your total is vials per session times sessions, within the label’s limits of 10 mL per treatment and 6 treatments. It is cosmetic and self-pay, and the 3-year data show most responders kept their results.
An InjectCo nurse injector will assess the area under your chin, estimate your vial count, and give you a quote before you commit.
Know your total before treatment.
