Most people need between 26 and 36 units of Botox for neck bands, depending on how many bands are visible on each side. The FDA-approved dosing for platysmal bands breaks down into three tiers: 26 units if you have one band on each side, 31 units if you have one band on one side and two on the other, and 36 units if you have two bands on each side. A separate technique called the Nefertiti Lift, which targets the jawline and upper neck together, uses 30 to 40 units total.
FDA-Approved Dosing for Platysmal Bands
Botox Cosmetic received FDA approval specifically for moderate to severe platysmal bands, the vertical cords that become more prominent in the neck with age and muscle activity. The approved protocol places small injections along each visible band and in the upper portion of the platysma muscle just below the jawline.
The exact breakdown works like this: your injector places 2 units at each of four sites in the upper platysma below the jawline on each side, then 1 unit at each of five sites along each vertical neck band. The total depends on how many bands you have:
- 1 band on each side: 26 units across 18 injection sites
- 1 band on one side, 2 on the other: 31 units across 23 injection sites
- 2 bands on each side: 36 units across 28 injection sites
That may sound like a lot of needle sticks, but each injection is tiny, just 0.025 mL of fluid per site on the bands themselves. The whole procedure typically takes 15 to 20 minutes.
Discrete Bands vs. Broad Neck Muscles
Not everyone’s neck anatomy is the same, and that affects both the injection technique and the total units used. People with clearly defined, rope-like bands get injections directly into the muscle. The injector grabs each band between their fingers and places about 2.5 units every 1 to 1.5 centimeters along its length.
People with broader, more diffuse neck muscles rather than distinct cords need a different approach. Injections go into the superficial skin layer in a horizontal pattern, spaced about 1.5 to 2 centimeters apart, with roughly 2.5 units per site. This pattern can require more total units because the treatment area is wider. Your injector will assess which pattern applies to you, and the unit count will adjust accordingly.
Units for a Nefertiti Lift
The Nefertiti Lift is a popular variation that targets both the jawline and the upper neck to create a sharper, more defined jaw contour. It uses 15 to 20 units per side, injected into the skin along the lower jawline and the upper neck where the platysma muscle pulls downward. Total dosing runs 30 to 40 units.
Practitioners cap the dose at 20 units per side per session to reduce the risk of complications. Keeping the total at or below 40 units helps prevent the toxin from migrating into deeper muscles that control swallowing and voice.
What Neck Botox Costs
Most clinics charge between $12 and $25 per unit for Botox, depending on your location and the injector’s experience. At those rates, a standard neck band treatment of 26 to 36 units runs roughly $310 to $900. A Nefertiti Lift at 30 to 40 units falls in a similar range. These are cosmetic treatments, so insurance does not cover them.
Some clinics charge a flat fee per treatment area rather than per unit. If you’re comparing quotes, always ask whether the price is per unit or per session, and how many units are included. Fewer units may cost less upfront but could also wear off faster.
How Long Results Last
You can expect to start seeing changes within 3 to 4 days, with full results visible at about 10 to 14 days. The effects generally last around 3 months, though this varies with the dose. Lighter dosing that looks more natural may fade in 6 to 8 weeks, while higher doses can hold for more than 6 months.
The neck tends to be an active area, with the platysma muscle engaging during facial expressions, talking, and chewing. That constant movement can shorten the duration compared to areas like the forehead. Most people schedule repeat treatments every 3 to 4 months to maintain results.
Side Effects to Know About
The most common minor side effects are bruising, swelling, and tenderness at the injection sites. These typically resolve within a few days. The more serious concern with neck Botox is difficulty swallowing, known clinically as dysphagia. This happens when the toxin spreads from the target muscle into nearby muscles involved in swallowing.
In studies of patients receiving botulinum toxin in the neck region (for cervical dystonia, which uses much higher doses than cosmetic treatments), about 16% experienced some degree of swallowing difficulty. Among those who developed it, nearly half noticed symptoms within the first 30 days after injection. Symptoms can include coughing while eating, needing longer to finish meals, or feeling like food isn’t going down easily.
For cosmetic neck treatments at the lower doses described above, the risk is considerably smaller. Precise, shallow injection technique and staying within recommended dose limits are the main safeguards. Using ultrasound guidance to map injection sites is an emerging approach that may further reduce the chance of affecting deeper muscles. If you have any existing swallowing issues, make sure your injector knows before treatment.
Who Gets the Best Results
Botox works best on neck bands that are caused primarily by muscle activity rather than loose or sagging skin. The ideal candidate has visible vertical cords that become more pronounced when clenching the jaw or grimacing, but relatively firm skin tone. If the main issue is excess skin or significant sagging, Botox alone is unlikely to produce a dramatic improvement, and a surgical or energy-based skin tightening procedure may be more appropriate.
Your injector should ask you to activate your platysma by clenching or grimacing during the consultation. If the bands pop out prominently with muscle contraction but flatten when the muscle relaxes, that’s a strong sign you’ll respond well to treatment. If the bands are visible even at rest with no muscle engagement, the underlying cause is more structural, and results from Botox alone will be limited.
