Neuromodulators

Botox, Dysport and Xeomin, chosen for your anatomy.

Our Philosophy

Why We Stock
All Three

We stock all three FDA-approved botulinum toxin type A products, because no one product is best for every patient or every area.

The active ingredient in all three is the same: botulinum toxin type A, which temporarily interrupts the acetylcholine signal at the neuromuscular junction. They differ in what surrounds it. Botox has the broadest FDA-approved label and the longest safety record. Dysport takes effect faster and spreads more widely, which suits some large treatment areas. Xeomin contains the purified neurotoxin alone, with no accessory proteins, which may matter for patients treated often over many years.

Dr. Schwartz looks at muscle mass, movement, treatment history and goals before choosing a product. Usually that takes five minutes; it takes longer if you have been treated elsewhere.

The products matter less than the injector

Marketing overstates the differences between these products. All three work. What matters more is skill, placement and dose. Choose the injector first; the product follows.

Units are not interchangeable

Botox and Xeomin share a roughly 1:1 unit ratio. It takes about 2.5 Dysport units to match one Botox unit. A price per unit that does not name the product is meaningless, and it often confuses patients.

Treatment Areas

What Neuromodulators
Treat

Neuromodulators treat dynamic lines: wrinkles formed by muscle movement, not by volume loss or sun damage. If a line is visible at rest, a neurotoxin alone will not erase it.

Upper Face
Forehead Lines
Horizontal lines from frontalis muscle activity. Dosing takes care, because over-treating the forehead creates heaviness.
Upper Face
Glabellar Lines
The vertical lines between the brows ("elevens") from corrugator and procerus muscles. FDA-approved indication for all three products.
Upper Face
Crow's Feet
Lateral canthal lines from orbicularis oculi contraction.
Mid Face
Bunny Lines
Diagonal lines across the nasal bridge from nasalis muscle activity. Often over-treated; a small correction is almost always enough.
Lower Face
Lip Lines & Lip Flip
A few units placed in the orbicularis oris soften the lines around the mouth and create a subtle lip flip, without filler.
Lower Face
Masseter & Jaw Slimming
Injecting the masseter muscle reduces bulk for a softer jawline. Also used therapeutically for bruxism and jaw pain.
Neck
Platysmal Bands
Vertical neck bands from platysma muscle activity. Botox holds the only FDA approval in the neck among the three products.
Brow
Brow Lift
Careful placement can lift the outer brow and open the eye without surgery.
Medical
Hyperhidrosis
Excessive underarm sweating responds reliably to neurotoxin treatment, with results lasting 6 to 12 months, longer than cosmetic treatments.

Each Product, Explained

Botox Cosmetic
OnabotulinumtoxinA
AbbVie (Allergan) · FDA Approved 2002

Botox is the reference product. It is not chemically better than the others; it has the longest clinical history, the most published safety data, and the broadest FDA-approved label of any neurotoxin in the United States. As of 2024, Botox Cosmetic holds FDA approval for four aesthetic areas: the glabella, the forehead, crow's feet and, alone among cosmetic neurotoxins, the platysmal bands of the neck.

How Botox spreads is well understood, and its dosing is the most thoroughly documented of the three. It behaves predictably in delicate areas like the lower eyelid, the lip border and the brow, where unwanted spread carries the highest aesthetic risk. For patients new to neuromodulators, or those who need very precise placement around the eyes, Botox is the most conservative choice.

The product contains the active 150 kDa neurotoxin along with accessory proteins that form a larger molecular complex. These proteins separate at the body's pH and do nothing therapeutically; they are left over from manufacturing. Neutralizing antibodies can develop but are rare at cosmetic doses.

Patients new to neuromodulators who want the most established safety record. Those who need precise treatment in sensitive areas: around the eyes, the lower face and the neck. Patients who want to treat platysmal bands without surgery, since Botox holds the only FDA approval for this among cosmetic neurotoxins. Patients with a long Botox history who get consistent results and see no reason to change.
All FDA-approved cosmetic areas: forehead, glabella, crow's feet, and platysmal bands. Off-label applications include brow lifting, bunny lines, lip lines, lip flip, masseter (jaw slimming), chin dimpling, hyperhidrosis, and gummy smile correction. Off-label use is common and well established in aesthetic practice. Dr. Schwartz discusses the evidence and the expected result for each area at your consultation.
Most patients experience results for 3 to 4 months. Duration is influenced by the number of units administered, the treatment area (forehead tends to last slightly longer than crow's feet), individual metabolism, and muscle mass. Men generally require higher doses and may notice shorter duration. Consistent treatment over time does not meaningfully extend duration, but it can reduce the depth of resting lines as the underlying muscle atrophies slightly with repeated use.
Onset4–5 days initial; peak at 10–14 days
Duration3–4 months average
Unit standardReference standard; 1:1 with Xeomin, 1:2.5 with Dysport
Best forPrecision areas, new patients, neck (platysma), full-face treatment

Dysport works faster and spreads more widely than Botox or Xeomin at equivalent clinical doses. Both differences hold up across multiple independent trials and come from real differences in the molecule.

The faster onset matters if you are scheduling treatment before an event. Clinical data consistently show initial results at 2 to 3 days for Dysport, compared with 4 to 5 days for Botox. If you have a wedding or an important appearance in ten days, that difference counts.

For large treatment areas, such as the whole forehead of a man with a thick, strong frontalis muscle or a broad upper-face treatment, the wider spread can give more even coverage with fewer injection points. In delicate areas near the eyes or in the lower face, where unwanted spread carries higher risk, Dr. Schwartz typically favors Botox or Xeomin. Dysport's unit ratio to Botox is approximately 2.5:1, so comparing per-unit prices without naming the product is meaningless.

Patients who want the fastest visible onset, particularly those timing treatment around an event. Patients with strong, thick frontalis or glabellar muscles who benefit from broader, more even spread. Patients who have used Dysport before and respond well to it. Those having larger upper-face treatments where even spread matters more than precise targeting.
Some patients and some studies do report slightly longer duration with Dysport, potentially up to 5 months versus the typical 3 to 4 for Botox. The mechanism may relate to the higher total amount of active neurotoxin delivered at FDA-approved doses. However, this is not universal, and individual variation in metabolism and muscle mass affects duration across all three products. Dr. Schwartz will not make a duration guarantee for any neurotoxin.
Each manufacturer uses a proprietary potency assay to measure their units, and those assay methods are not standardized across products. As a result, 50 Dysport units are not equivalent to 50 Botox units; they are approximately equivalent to 20 Botox units. This is why the FDA explicitly states that neurotoxin units are not interchangeable. Quoting per-unit prices without naming the product is one of the most common sources of confusion in the injectable market.
Onset2–3 days initial; peak at 10–14 days
Duration3–5 months; potentially longer than Botox in some patients
Unit ratio~2.5:1 vs. Botox (50 Dysport units ≈ 20 Botox units)

Xeomin
IncobotulinumtoxinA
Merz Pharmaceuticals · FDA Approved 2010
+

Xeomin is the newest of the three and the most purified. It contains only the 150 kDa neurotoxin, the part responsible for the clinical effect, without the accessory proteins in Botox and Dysport. Merz calls this XTRACT Technology; clinicians more often call it "the naked toxin."

Because Xeomin has no accessory proteins, it may be less likely to provoke antibodies. Accessory proteins play no part in the clinical effect, but they do stimulate the immune system to make antibodies. Over time, some patients treated often develop neutralizing antibodies that make the product less effective. Because Xeomin carries less foreign protein per treatment, the theoretical risk of antibodies causing treatment to fail may be lower. The research is less clear-cut than early Xeomin marketing suggested (immunogenicity depends on how often you are treated and the total protein load, not on formulation alone), but if you are treated often over many years, it is worth discussing.

Xeomin has the same unit ratio and spread as Botox. Onset is slightly faster than Botox, at 2 to 3 days. Xeomin can also be stored at room temperature for up to four years; Botox and Dysport must be refrigerated.

Patients who have had neurotoxin treatments for many years and want to minimize long-term antibody risk. Those who have found Botox or Dysport less effective over time, which can be a sign that neutralizing antibodies are developing. Patients who prefer a product with no accessory proteins for personal reasons. Anyone who wants Botox-equivalent precision and dosing with slightly faster onset.
The theory is well established: accessory proteins stimulate an immune response, and Xeomin contains none. What is less clear is how much this matters at cosmetic doses, which are far lower than the therapeutic doses used in the studies of neutralizing antibodies. Dr. Schwartz presents it as a possible long-term consideration for patients treated often, not a guaranteed advantage. There is not yet definitive long-term comparative data at cosmetic doses.
Multiple randomized controlled trials have shown Xeomin to be no less effective than Botox at equivalent unit doses for glabellar lines and crow's feet. Patients cannot tell them apart by the result. Onset with Xeomin is slightly faster (2 to 3 days versus 4 to 5 for Botox), and the spread is comparable. Patients switching from Botox to Xeomin use the same dose and placement and get a similar result.

The Experience

What to Expect

Most appointments take 20 to 30 minutes from arrival to departure.

Before

Preparation

Avoid aspirin, ibuprofen, naproxen, fish oil, vitamin E, and alcohol for one week beforehand to minimize bruising. No other special preparation is required. Arrive with a clean face, with no makeup in treatment areas.

During

The Treatment

Dr. Schwartz watches how your face moves before injecting. Fine needles are used throughout. Discomfort is minimal: a brief pinch at each site. Most patients don't need anesthesia; numbing cream is available on request.

After

Immediately Post

Small bumps at injection sites resolve within 20 to 30 minutes. Avoid lying flat, exercise, and alcohol for four hours. Minor bruising is possible and resolves within 3 to 7 days. No downtime is required.

Results

Onset & Follow-Up

Dysport and Xeomin: initial effect at 2 to 3 days. Botox: 4 to 5 days. All products reach full effect at 10 to 14 days. A complimentary two-week check is offered for all first-time Edition patients.

Questions

What Patients Ask

The questions we hear most often.

All three are FDA-approved botulinum toxin type A products that work by temporarily relaxing facial muscles. They differ in formulation, onset speed, diffusion pattern, and unit potency. Botox has the broadest FDA-approved label and the most established safety record. Dysport tends to show results faster and diffuses slightly more broadly, making it well-suited for larger treatment areas. Xeomin contains only the pure neurotoxin without accessory proteins, which may offer advantages for patients receiving frequent long-term treatments. In practice, all three give comparable results when the right product is chosen and injected well.

Results typically last 3 to 5 months, with Dysport occasionally lasting slightly longer in some patients. Duration varies based on the product, the number of units administered, the treatment area, individual metabolism, and muscle mass. Men generally experience shorter duration due to larger muscle mass. Consistent, appropriate-interval treatments over time tend to produce more stable results than sporadic, high-dose treatments.

Only if over-treated. The frozen look comes from the dose and placement, not from the products themselves. Dr. Schwartz aims to soften the lines that bother you while keeping your expression. Most patients go back to work the same day.

Discomfort is minimal: a brief, mild pinch at each injection site. The needles are very fine, and the amount injected at each site is small. Treatments are typically complete in under 15 minutes of actual injection time. Most patients don't need anesthesia; numbing cream is available on request.

Edition prices neurotoxin treatments per unit, and you get the price at your consultation. Because units are not interchangeable between products (it takes about 2.5 Dysport units to match one Botox unit), a per-unit price only means something when it names the product. You get an itemized treatment plan before treatment, so the bill at checkout is the one you agreed to.

Yes, and it is common. Neuromodulators treat lines caused by movement; fillers treat volume loss. Many patients have both at one appointment.

Before: avoid aspirin, ibuprofen, naproxen, fish oil, vitamin E, and alcohol for one week to minimize bruising. After: avoid lying flat, strenuous exercise, facial massage, and alcohol for four hours. Do not rub or apply pressure to treated areas for 24 hours. Arnica gel or bromelain can help resolve any bruising faster if needed.

Neuromodulator treatments are not performed during pregnancy or while breastfeeding. There is no established safety data for botulinum toxin use in pregnancy, and Edition does not make exceptions. If you are planning a pregnancy soon, tell Dr. Schwartz at your consultation so your treatments can be timed around it.
