Botox vs. Letybo: The Comparison Guide
Reviewed for medical accuracy against our Medical Review Board · Last updated 15 August 2026
Part of Botox vs Other Neurotoxin Brands
The newest botulinum toxin approved for use in the United States, measured against the one everyone knows.
Botox has set the gold standard in wrinkle treatments for over two decades. But a new competitor, Letybo, is gaining attention in the aesthetic industry, especially as Korean skincare and injectables rise in popularity. Marketed as a cost-effective and highly purified botulinum toxin, Letybo is often called the "Korean Botox." But how does it compare to the trusted Botox brand?
This comprehensive guide breaks down everything patients need to know about Botox vs. Letybo, from how they work and what they’re approved for to safety, pricing, onset, longevity, and patient experiences.
1. Two different treatments: Botox and Letybo
1.1 Definitions and Origins
Botox (OnabotulinumtoxinA): Developed by Allergan (now part of AbbVie), Botox is the most widely known and researched botulinum toxin globally. It’s FDA-approved for both cosmetic and therapeutic uses.
Letybo (Botulinum toxin type A): Created by Hugel, a South Korean pharmaceutical company, Letybo is marketed primarily for cosmetic purposes and is one of the top-selling toxins in Asia and parts of Europe.
1.2 Mechanism of Action
Both products temporarily block nerve signals to muscles, reducing the appearance of dynamic wrinkles. This leads to smoother skin by preventing repetitive facial movements that cause lines.
1.3 FDA Approval and Global Use
- Botox: FDA-approved in the U.S. since 2002 for cosmetic use, with earlier medical approvals since the 1980s. Approved in over 100 countries.
- Letybo: Approved in South Korea, China, and parts of Europe. It received Health Canada approval in 2022 and is expected to seek FDA approval for the U.S. market.
1.4 Formulation and Manufacturing
- Botox: Produced in Ireland with a stable formulation that includes protective proteins.
- Letybo: Manufactured using Hugel’s proprietary purification system that claims high purity and consistent particle size. It contains 0.5 mg of human serum albumin and 0.9 mg of NaCl per vial.
2. Where Botox and Letybo genuinely differ
2.A Molecular Structure & Stability
- Both use botulinum toxin type A, but the manufacturing and purification processes differ.
- Letybo is marketed for its high purity and consistent molecular weight, which may reduce diffusion and enhance precision.
2.B Official Indications
- Botox: Glabellar lines, forehead lines, crow’s feet (cosmetic) + multiple medical uses (migraines, hyperhidrosis, TMJ, etc.)
- Letybo: Approved for glabellar lines in several countries; other uses are off-label in most regions
2.C Diffusion and Spread
Early studies and clinical usage suggest:
- Botox: Slightly more predictable diffusion based on decades of data.
- Letybo: Some clinicians note less spread, allowing for precise targeting, but more research is needed.
2.D Unit Conversion and Dosing Guidelines
- In clinical practice, Letybo is often used at a 1:1 ratio with Botox.
- Ongoing studies aim to confirm long-term dosing equivalency.
2.E Shelf Life and Storage
- Both products are stored refrigerated and reconstituted before injection.
- Letybo is said to maintain stability well post-reconstitution when handled properly.
3. Results compared
3.A Onset of Action
- Botox: Effects appear in 3–5 days, peak at 10–14 days
- Letybo: Onset reported between 2–4 days, peak around 7–10 days
3.B Duration of Effects
- Botox: Lasts 3–4 months
- Letybo: Most patients report a similar duration, though real-world longevity is still being assessed as it enters broader markets
3.C Aesthetic Outcomes
Both products can produce natural-looking results when administered correctly. Some clinicians using Letybo report a smoother finish with slightly less muscle stiffness.

Final Thoughts: Botox vs. Letybo
Botox remains the industry leader in neuromodulators with FDA approval for both cosmetic and medical uses, global research backing, and consistent results.
Letybo, while newer in Western markets, is a compelling option, especially for patients looking for an affordable, highly purified cosmetic toxin.
If you’re seeking a trusted, all-purpose injectable with a long track record, Botox is your go-to. If you’re curious about Korean injectables and want to save money without sacrificing results, Letybo is worth exploring.
As always, speak with your injector to determine which product aligns with your facial anatomy, lifestyle, and treatment goals.
One approved area against four
LETYBO's US label, effective 18 November 2024, indicates it for the temporary improvement of moderate to severe glabellar lines associated with corrugator and procerus muscle activity. That is its only cosmetic indication.
BOTOX Cosmetic holds four: glabellar lines, lateral canthal lines, forehead lines and platysma bands. So on breadth this is not a close comparison, and any clinic offering Letybo for the forehead or crow's feet is using it off-label, which is legal but worth knowing.
On the area they share, the two are dosed the same: 4 Units into each of five sites, 20 Units in total. Letybo is a newer arrival rather than a weaker drug, and for frown lines specifically the labelled regimen is the one you already know.
The practical question is therefore price and availability rather than potency. Our Letybo guide covers the product in full.
Frequently asked questions
How well does Letybo work?
Its three trials, which the label describes as identical in design, reported 47%, 49% and 65% success at Week 4 against placebo rates of 0%, 2% and 0%. That 18-point spread across the same protocol is worth more than any single figure: it shows how much a trial result moves with the sites and the people enrolled, and it is why setting Letybo’s number beside another brand’s proves very little.
Is Letybo approved for the same things as Botox?
No. Letybo is approved for moderate to severe glabellar lines in adults and nothing else, where Botox holds four cosmetic approvals and numerous medical ones. Anything beyond the lines between the brows is off-label with Letybo, which is legal but means no reviewed dose and no trial data for that area.
Is Letybo safe, given it comes from a Korean manufacturer?
The origin is not the safety question, and the two get confused constantly. Letybo is made by Hugel, a Korean company, and it is fully FDA-approved for use in the United States after a trial programme of 1,276 people. That is entirely different from the unapproved imported toxins the FDA has warned about, which have no US approval at all. Check that what you are being given carries a US NDC number on the vial.
How many units of Letybo will I need?
Twenty, for the one area it is approved to treat: 4 Units into each of five sites, one in the procerus and two in each corrugator. That is the same labelled dose and the same injection map as Jeuveau. It is not comparable to a Botox unit count, because each product’s potency is measured by its own assay.
Why might a clinic price Letybo lower?
There is a structural reason as well as a competitive one. Both labels state that a vial is single-dose, used for one injection session and one patient, with the remainder discarded. A 20 unit treatment from a 100 Unit vial therefore destroys 80 Units. Letybo also comes in a 50 Unit vial, where only 30 are wasted, and several competing products have no smaller option. That difference is real cost, not a promotion.
