What Are Letybo® Injections?
Letybo® (letibotulinumtoxinA-wlbg) is an FDA-approved botulinum toxin type A injectable that works as an acetylcholine release inhibitor and neuromuscular blocking agent. It is specifically indicated for the temporary improvement of moderate to severe glabellar lines, commonly known as the “11s” between the eyebrows. Letybo has been widely used globally and is backed by strong clinical studies and safety data.
How it works
Letybo targets the neuromuscular junction, where nerve signals trigger muscle activity. By limiting the release of acetylcholine, the treatment reduces contractions in the procerus muscle and surrounding muscles responsible for frown lines.
As these muscles relax, the skin smooths out, leading to a softer, more refreshed appearance.
Key Benefits of Letybo Injections
Patients choose letybo injections for their combination of effectiveness and convenience:
- Clinically proven to improve moderate to severe glabellar lines
- Smooths frown lines while preserving natural facial movement
- Fast-acting results, often within a few days
- Full results typically visible in about 2 weeks
- Results typically last 3 to 4 months
- Non-surgical with minimal downtime
- Highly purified formula for consistent, natural-looking outcomes
- Widely trusted globally prior to U.S. FDA approval
Letybo offers a trusted option for patients looking to reduce the visible effects of repeated muscle strength and expression over time.
Treatment Areas and Common Uses
While Letybo is approved for the treatment of glabellar lines, it is commonly used to enhance multiple areas of the face:
- Glabellar lines between the brows (11’s)
- Forehead lines
- Crow’s feet around the eyes
- Bunny lines on the nose
- Lip lines or lip flip treatments
- Chin dimpling
Your provider at Universal Dermatology will customize your treatment plan based on your unique facial anatomy and goals.

Safety and Potential Side Effects
Letybo has been evaluated in clinical studies and has a strong safety profile when administered by a qualified healthcare provider.
Most patients experience minimal, temporary side effects such as mild redness, swelling, or tenderness at the injection site. These effects typically resolve quickly and do not interfere with daily activities.
As with any treatment involving botulinum toxin products, there is a possibility of side effects. Your provider will review your medical history and discuss any potential risks to ensure Letybo is a safe and appropriate option for you.
