Letybo
Letybo (letibotulinumtoxinA-wlbg) is a modern, highly purified botulinum toxin type A injectable approved by the FDA in 2024 to temporarily soften moderate to severe glabellar lines (the vertical "11s" between the eyebrows). Developed by Hugel and already established globally across Asia and Europe, Letybo provides an effective, precision alternative to legacy neurotoxins.
Patients frequently explore Letybo when seeking a subtle, expressive result with rapid onset. Because it is manufactured with advanced purification standards that remove unnecessary accessory proteins, Letybo minimizes foreign protein load while delivering predictable relaxation of targeted facial muscles at an accessible price point.
Sessions
Administered in a quick 10-15 minute visit. Most patients maintain results by scheduling repeat sessions every 3-4 months.
Downtime
Virtually zero downtime. Minor injection site redness or tiny pinprick marks typically resolve within 15-30 minutes.
Results timeline
Patients often notice initial muscle softening within 2-3 days, reaching maximum smoothing at 10-14 days. Longevity is typically 3-4 months.
Typical cost
Nationally, Letybo is typically priced around $9-$15 per unit, often offering a 15-20% cost savings compared to legacy brands like Botox.
Credentials
Who performs it
Letybo is a prescription medical aesthetic product administered under physician supervision by licensed injectors—including registered nurses (RN), nurse practitioners (NP), physician assistants (PA), and board-certified doctors (MD/DO)—who are trained in facial kinetics and micro-dosing.
Before you book
Worth considering
- Letybo delivers comparable duration (3-4 months) and safety profiles to Botox and Dysport in rigorous clinical trials.
- Remain upright for at least 4 hours following treatment and avoid strenuous exercise or saunas for 24 hours.
- Ask your provider how their practice prices neurotoxins (by the unit vs. by the anatomical zone).
- A consultation will review your dynamic facial anatomy to ensure natural preservation of personal facial expressions.

Letybo questions
Letybo vs. Botox: What is the difference?
Both Letybo and Botox use botulinum toxin type A to temporarily relax the facial muscles that cause frown lines. The primary differences lie in the manufacturer, proprietary purification techniques, and pricing. Letybo clinical trials showed onset as early as 2 to 3 days (often slightly faster than Botox) and equivalent longevity of 3 to 4 months. Because Letybo entered the US market recently, med spas often price it slightly lower than Botox, giving patients equivalent efficacy at a lower cost per unit.
Is Letybo FDA approved in the United States?
Yes. Letybo received FDA approval in early 2024 for the treatment of moderate to severe glabellar lines (frown lines between the eyebrows) in adult patients, backed by extensive global safety and efficacy trials involving over 1,200 subjects across three Phase III studies.
How many units of Letybo will I need?
For the standard FDA-approved treatment of glabellar lines (the 11s), the typical dose is 20 units distributed across five specific injection sites (the procerus muscle and paired corrugator supercilii muscles). Depending on individual muscle mass and facial dynamics, men or patients with stronger expression lines may benefit from 24-30 units.
How long does Letybo last?
In clinical studies, Letybo results lasted an average of 3 to 4 months. As neuromuscular signaling gradually restores over time, muscle movement returns and lines gently reappear, at which point a maintenance touch-up can be performed.
