Botox, Dysport, Xeomin, Jeuveau, Daxxify & Letybo — What's the Difference?

When most people think about wrinkle-relaxing injections, one name immediately comes to mind: Botox.

But did you know Botox is actually a brand name, not the name of the treatment itself?

Today, there are six FDA-approved botulinum toxin type A products available for cosmetic use in the United States. Although they share a similar mechanism of action, each has its own formulation, dosing requirements, clinical research, and treatment characteristics.

Understanding these differences can help you feel more informed and confident when exploring aesthetic treatments.

First, What Exactly Is a Neurotoxin?

Neuromodulators, commonly called neurotoxins in aesthetics, are prescription medications that temporarily reduce targeted muscle activity.

Every time we smile, frown, squint, or raise our eyebrows, our facial muscles contract. Over time, repeated movements contribute to dynamic wrinkles—lines that appear during facial expression.

Botulinum toxin type A works by temporarily blocking the release of acetylcholine, a chemical messenger responsible for signaling muscle contraction.

When carefully administered, these treatments can soften the appearance of expression lines while preserving natural-looking facial movement.

The goal isn't necessarily to eliminate every wrinkle. It's to create a balanced, refreshed appearance that complements your natural features.

Meet the Six Cosmetic Neurotoxins

1. Botox Cosmetic — The Familiar Name

Active ingredient: OnabotulinumtoxinA

Botox Cosmetic is one of the most recognized names in aesthetic medicine and has an extensive history of clinical use.

It is FDA-approved for temporarily improving certain facial expression lines, including frown lines, forehead lines, and crow's feet.

Results typically begin developing within several days, with full results generally assessed around two weeks. The effects commonly last approximately three to four months, although individual experiences vary.

Its long clinical history and extensive research make Botox Cosmetic a familiar option for both patients and aesthetic providers.

2. Dysport — A Different Formulation

Active ingredient: AbobotulinumtoxinA

Dysport is another established botulinum toxin type A product, FDA-approved for the temporary improvement of moderate to severe frown lines between the eyebrows in adults.

Some patients notice improvement within the first few days, although response times vary.

Dysport has its own dosing system, which means its units cannot be directly compared with Botox units.

You may hear that Dysport spreads more or works faster than other products. While formulation and injection characteristics differ, these claims should not be treated as universal advantages. The treatment area, dose, technique, and individual response all matter.

3. Xeomin — A Formulation Without Complexing Proteins

Active ingredient: IncobotulinumtoxinA

Xeomin is sometimes described as a more purified or "naked" neurotoxin because its formulation does not contain accessory complexing proteins.

Like the other products discussed here, Xeomin temporarily reduces targeted muscle activity.

Its cosmetic FDA approvals include treatment of certain upper facial expression lines.

The absence of complexing proteins is a formulation distinction, but it does not automatically mean Xeomin is safer, more natural-looking, or better for everyone.

Treatment results and longevity vary by individual.

4. Jeuveau — Developed for Aesthetic Treatment

Active ingredient: PrabotulinumtoxinA-xvfs

Jeuveau entered the U.S. aesthetic market in 2019 and is FDA-approved for temporarily improving moderate to severe frown lines between the eyebrows.

It was introduced with a focus on cosmetic applications and is sometimes informally called "Newtox."

Jeuveau works through the same general mechanism as other botulinum toxin type A products, but it has its own manufacturing process and clinical data.

As with other neurotoxins, results are temporary, and maintenance treatments may be needed to sustain the desired appearance.

5. Daxxify — A Longer-Duration Option for Some Patients

Active ingredient: DaxibotulinumtoxinA-lanm

Daxxify stands out because of its peptide-based formulation and clinical studies demonstrating a longer duration of effect for some patients.

It is FDA-approved for temporarily improving moderate to severe frown lines between the eyebrows.

In pivotal clinical studies, the median duration of maintained improvement was approximately six months using specific study criteria. This does not mean every patient will experience six months of results.

Some individuals may experience a shorter duration, while others may maintain improvement longer.

Daxxify offers an interesting option for patients who value potentially longer intervals between treatments, although it is not automatically the best choice for every face or treatment goal.

6. Letybo — A Newer U.S. Option

Active ingredient: LetibotulinumtoxinA-wlbg

Letybo received FDA approval in 2024 for temporarily improving moderate to severe frown lines between the eyebrows in adults.

Although newer to the United States, the product has an established history in international aesthetic markets.

Like the other neurotoxins, Letybo works by temporarily reducing targeted muscle activity.

Its introduction provides another FDA-approved option for qualified aesthetic providers and their patients.

As with any prescription injectable, the appropriate choice depends on the individual's anatomy, medical history, treatment goals, and the provider's clinical assessment.

Are All Neurotoxins Basically the Same?

They belong to the same general treatment category and share a similar mechanism of action, but they are not identical medications.

Differences may include:

• Formulation and manufacturing processes

• Product-specific dosing and potency measurements

• FDA-approved treatment indications

• Clinical onset and duration data

• Individual response and treatment experience

Importantly, neurotoxin units are not interchangeable between brands.

For example, 20 units of one product should not automatically be considered equivalent to 20 units of another. Each product has its own FDA-approved dosing recommendations and potency measurements.

This is why choosing a neurotoxin should involve more than comparing the price per unit.

Which Neurotoxin Lasts the Longest?

This is one of the most common questions patients ask.

Many traditional cosmetic neurotoxin treatments produce results lasting approximately three to four months, although some patients experience shorter or longer effects.

Daxxify has demonstrated a longer median duration of improvement in its clinical trials for frown lines.

However, comparing duration across brands is not always straightforward because studies may use different doses, populations, evaluation methods, and definitions of treatment success.

Your metabolism, muscle activity, treatment area, dosing, and individual response can also influence how long your results remain noticeable.

Can GLP-1 Medications Affect How Long Neurotoxins Last?

With the growing popularity of medical weight-loss treatments such as semaglutide and tirzepatide, researchers are beginning to explore how these medications—and the physiological changes associated with weight loss—might influence aesthetic treatment outcomes.

One emerging area of interest is whether GLP-1-based medications could affect the duration of botulinum toxin treatments.

A 2025 computational modeling study published in Toxicon predicted that botulinum toxin effects might wear off sooner in patients using certain GLP-1-based medications. Researchers explored potential mechanisms involving neuromuscular signaling, metabolic changes, and changes in lean body mass.

However, these findings were based on computer simulations rather than clinical trials involving actual patients. At present, there is insufficient clinical evidence to conclude that GLP-1 medications directly shorten the effects of Botox or other cosmetic neurotoxins.

Significant weight loss can also change facial volume, skin laxity, and the appearance of fine lines. These changes may influence how patients perceive their overall aesthetic results, even when the neurotoxin continues to affect the treated muscles.

What does this mean for patients?

If you're currently using a GLP-1-based medication or experiencing significant weight loss, it's important to share this information with your aesthetic provider.

An individualized assessment can help establish realistic expectations, evaluate changes in facial anatomy, and determine an appropriate treatment and follow-up plan.

As research continues to evolve, informed treatment decisions should be guided by clinical evidence rather than assumptions about medication-related effects.

Will Neurotoxins Make My Face Look Frozen?

Not necessarily.

A frozen or overly restricted appearance is not an inevitable result of neurotoxin treatment.

Natural-looking results depend on several factors, including facial anatomy, muscle strength, dosing, injection placement, and the desired degree of movement reduction.

Some patients prefer very subtle softening, while others want a more noticeable reduction in expression lines.

Neither approach is universally right or wrong.

A thoughtful treatment plan should consider how your face moves, not simply where wrinkles appear.

Are Neurotoxins Only for Existing Wrinkles?

Not always.

Some adults choose neurotoxin treatments before expression lines become deeply established. This approach is commonly referred to as preventative aesthetics.

By temporarily reducing repetitive muscle contractions, treatment may help limit the continued deepening of certain dynamic expression lines.

However, neurotoxins cannot prevent all wrinkles or stop the natural aging process.

Skin quality, genetics, sun exposure, lifestyle, and collagen changes also influence facial aging.

A comprehensive approach to skin health may include sun protection, appropriate skincare, and individualized aesthetic treatments.

What About Safety?

Although cosmetic neurotoxins are widely used, they are prescription medications and should be treated with appropriate medical consideration.

Potential side effects include temporary redness, bruising, swelling, headache, unwanted muscle weakness, facial asymmetry, or eyelid or brow drooping.

Rare but serious complications can occur. All FDA-approved botulinum toxin products carry a boxed warning regarding the possible spread of toxin effects beyond the injection site, which may cause difficulty swallowing, speaking, or breathing. These symptoms require immediate medical attention.

Treatment may not be appropriate for everyone, including individuals with certain medical conditions, allergies, or infections at the proposed injection site.

Always disclose your medical history, medications, previous neurotoxin treatments, and any history of adverse reactions before receiving treatment.

Choosing a properly licensed, qualified healthcare professional who uses authentic FDA-approved products is essential.

So, Which Neurotoxin Is Best?

The answer isn't necessarily Botox, Dysport, Xeomin, Jeuveau, Daxxify, or Letybo.

The best neurotoxin is the one appropriately selected for your individual needs.

Your facial anatomy, muscle movement, aesthetic goals, medical history, and treatment preferences are more important than choosing a product simply because it's popular.

A consultation provides the opportunity to discuss available options, understand realistic expectations, and develop a treatment plan tailored to you.
