Letybo vs. Botox: What Is the Newest Neurotoxin and How Does It Compare?
An honest comparison of Letybo and Botox covering formulation, onset, duration, and when each is the right choice.
Reviewed by Dr. Leslie Apgar, MD | Pura Vida Med Spa, Fulton and Marriottsville, MD
The neurotoxin market has changed considerably over the past few years. For decades, Botox held a near-monopoly as the only FDA-approved cosmetic neurotoxin most patients had heard of. Then Dysport arrived, then Xeomin, then Daxxify in 2022, and most recently Letybo in 2024, the newest FDA-approved neurotoxin available in the United States.
At Pura Vida Med Spa in Fulton and Marriottsville, MD, we offer Letybo alongside Daxxify and Dysport, and the most common question we hear is a reasonable one: is the newest product actually better, or does it just have a newer name? The answer, as always with neurotoxins, is that it depends on what you are looking for.

What Is Letybo?
Letybo (prabotulinumtoxinA-xvfs) is manufactured by Hugel, a South Korean biotechnology company. While it received FDA approval in the United States in February 2024 for the treatment of glabellar lines, it is not a new product in the broader sense. It has been in clinical and commercial use in South Korea for over a decade under the brand name Botulax, and has been available across Asia, Europe, and other international markets for years before its US launch.
This is clinically significant. When a neurotoxin receives FDA approval, it brings with it whatever real-world safety data exists from its prior use globally. Letybo arrives with a meaningful international track record, which is a different situation from a genuinely first-in-class product with only trial data behind it.
Letybo is a botulinum toxin type A product that works through the same mechanism as Botox: it blocks the release of acetylcholine at the neuromuscular junction, temporarily preventing targeted muscles from contracting. This reduces the dynamic wrinkles, lines created by facial movement, in the treated area. What differs between Letybo and Botox is not the mechanism but the formulation, stabilization chemistry, and some aspects of the clinical profile.
The Key Formulation Difference: No Human Serum Albumin
This is the most clinically notable difference between Letybo and Botox, and it parallels the distinction Daxxify also makes. Botox uses human serum albumin as a stabilizing excipient, a protein that holds the toxin molecule in a stable, deliverable form. Letybo uses sucrose and polysorbate 20 instead.
This matters for a specific subgroup of patients: those who prefer to avoid human-derived blood products in their treatments. It also may be relevant to the theoretical long-term question of antibody formation, since albumin-containing proteins are potentially immunogenic over many repeated treatments. Letybo's formulation eliminates human serum albumin entirely from the product.
Like Daxxify, Letybo's formulation represents the newer direction of neurotoxin development: animal-protein-free, highly purified, and stabilized with synthetic or non-protein excipients.
Onset: Where Letybo Stands Out
Letybo's most clinically distinctive feature is its fast onset. In clinical trials and in practice, many patients begin to see initial results within 24 to 72 hours of treatment, with some patients noticing early softening of expression lines as soon as the day after their appointment. This compares favorably to Botox's typical onset of 3 to 7 days and Daxxify's similar timeline of 3 to 7 days.
For patients who schedule neurotoxin treatment in advance of an event or occasion, faster onset is a practical advantage. It also reduces the uncertainty window during which patients wonder if the treatment is working.
Duration: Comparable to Botox
Unlike Daxxify, which offers a distinctly longer duration of 4 to 6 months, Letybo's duration is comparable to Botox: most patients see results lasting 3 to 4 months. This is not a disadvantage. It means that patients who have established a comfortable 3 to 4 month treatment cycle and prefer that cadence can switch to Letybo without changing their scheduling routine, while gaining the faster onset and albumin-free formulation.
For patients who specifically want longer-lasting results and are willing to trade faster onset for duration, Daxxify remains the better fit. For patients who prioritize quick onset, high product purity, and an equivalent treatment cycle to Botox, Letybo is the more appropriate choice.
Side-by-Side Comparison
| Feature | Letybo | Botox |
|---|---|---|
| Active ingredient | PrabotulinumtoxinA-xvfs | OnabotulinumtoxinA |
| Manufacturer | Hugel (South Korea) | Allergan/AbbVie (USA) |
| Stabilizing excipients | Sucrose and polysorbate 20 | Human serum albumin |
| Animal/human protein free | Yes | No |
| FDA approval (cosmetic) | 2024 (glabellar lines) | 2002 (glabellar, crow's feet, forehead) |
| Onset | 24 to 72 hours (fast) | 3 to 7 days |
| Duration | 3 to 4 months | 3 to 4 months |
| Unit dosing | Approximately 1:1 with Botox | Standard reference units |
| International track record | 10+ years (South Korea, Asia, Europe) | 20+ years globally |

FDA approval information for prabotulinumtoxinA-xvfs (Letybo) is published by the U.S. Food and Drug Administration.
When Letybo Is the Better Choice
- Patients who want fast onset: results beginning in 24 to 72 hours rather than the typical 3 to 7 days with Botox or Daxxify
- Patients who prefer an animal-protein-free and human-serum-albumin-free formulation
- Patients who want to maintain their current 3 to 4 month treatment schedule without changing cadence
- Patients who have used Botox satisfactorily but are curious about a newer, highly purified alternative with extensive international safety data
- Patients with specific sensitivities to human serum albumin or animal-derived proteins
When Botox (or Another Neurotoxin) Is Still the Right Answer
- Patients who need therapeutic uses: Botox has extensive FDA-approved therapeutic indications (hyperhidrosis, chronic migraine, cervical dystonia, overactive bladder) that Letybo does not currently share in the US market
- Patients who specifically want longer duration: Daxxify, not Letybo, is the product for patients seeking 4 to 6 months of results
- Patients who have had excellent long-term results with Botox and have no motivation to change: if it works reliably, switching is optional not required
- First-time neurotoxin patients where provider preference guides product selection: at Pura Vida, Dr. Apgar's team will discuss which starting product makes the most sense given your anatomy and goals

Frequently Asked Questions: Letybo vs Botox
Is Letybo the same as Botox?
No. Letybo (prabotulinumtoxinA-xvfs) and Botox (onabotulinumtoxinA) are both botulinum toxin type A products made by different manufacturers using different formulations. Both work through the same mechanism of action, blocking acetylcholine release at the neuromuscular junction, but they differ in stabilizing excipients, onset speed, and manufacturer. Letybo contains no human serum albumin, while Botox does.
Does Letybo work faster than Botox?
Yes, in most patients. Letybo's most clinically notable feature is fast onset, with many patients seeing initial results within 24 to 72 hours of treatment. Botox typically takes 3 to 7 days to begin working, with full effect at 2 weeks. Both products reach their complete result at approximately 14 days, but the early-stage difference in onset is meaningful for patients who want to see changes quickly.
How long does Letybo last?
Letybo results typically last 3 to 4 months for most patients, comparable to Botox. Patients who specifically want longer-lasting results of 4 to 6 months may be better suited to Daxxify. Your provider at Pura Vida will discuss which product duration matches your goals and scheduling preferences.
Can I switch from Botox to Letybo?
Yes. Switching from Botox to Letybo is clinically straightforward. Letybo units have an approximately 1:1 equivalency with Botox units, which simplifies dose translation. Your Pura Vida provider will review your current Botox dosing and areas treated before recommending an equivalent Letybo protocol. Many patients find the transition seamless.
Is Letybo safe?
Letybo has an extensive international safety record from over a decade of commercial use in South Korea, Europe, and other markets before its FDA approval in the United States. FDA approval itself requires rigorous clinical trial evidence of both safety and efficacy. At Pura Vida, Letybo is administered by Dr. Apgar's licensed medical team following all established protocols for neurotoxin injection.
Is Letybo available in Fulton and Marriottsville, MD?
Yes. Letybo is available at both Pura Vida Med Spa locations in Fulton (Maple Lawn) and Marriottsville, MD. To discuss whether Letybo is the right neurotoxin for your goals, schedule a consultation with Dr. Apgar's team.
