Smooth the “11s” between your brows — naturally expressive, not frozen.
LETYBO® (letibotulinumtoxinA-wlbg) is FDA-approved for the temporary improvement of moderate to severe glabellar lines (frown lines between the eyebrows) in adults.
A confident look starts with a confident plan.
We map facial movement first, then dose conservatively for balance and symmetry. You’ll know what we’re treating, why we’re treating it, and what to expect after your visit.
Medical aesthetics, planned like medicine
We evaluate symmetry and movement first, then build a conservative plan that prioritizes safety and natural-looking results. This approach reduces over-treatment and supports a refreshed—not “done”—appearance.
Designed for every face — women and men
The objective is the same: a refreshed look that still reads like you. Treatment plans are tailored to facial structure, muscle strength, and your preferred result.
For Women
- Softens vertical “11” lines between the eyebrows.
- Helps reduce a tense or fatigued resting expression.
- Conservative dosing supports natural movement.
For Men
- Reduces a stern or stressed appearance.
- Plans account for typically stronger brow musculature.
- Maintains a natural, masculine expression.
What LETYBO® Treats
LETYBO® is FDA-approved for the temporary improvement of moderate to severe glabellar lines — commonly called the “11s” between the eyebrows. These lines form from repeated muscle movement in the corrugator and procerus muscles.
Best for:
- Vertical frown lines between the eyebrows
- A tense or stern resting facial expression
- Early or moderate dynamic forehead tension
- Patients seeking subtle, natural refinement
Treatment is individualized based on facial movement strength, anatomy, and desired outcome.

Frequently asked questions
Clear answers help you make an informed decision about LETYBO® treatment.
How long does LETYBO take to work?
Most patients begin noticing changes within several days, with continued improvement as the treatment settles. Exact timing varies by individual muscle activity and dosing.
How long do results last?
Results are temporary. Duration varies by individual metabolism and muscle strength. Maintenance appointments are typically scheduled based on your response and aesthetic goals.
Will I look frozen?
The goal is not to eliminate expression, but to soften excessive muscle contraction. Treatment planning focuses on balance and natural facial movement.
Is the treatment painful?
Most patients describe the injections as brief, small pinches. The procedure is quick and performed in-office without anesthesia.
Are there risks?
All medical treatments carry potential risks. LETYBO® contains botulinum toxin and should be administered by a licensed medical professional. Full safety information is reviewed during consultation.

IMPORTANT SAFETY INFORMATION for LETYBO® (letibotulinumtoxinA
wlbg) Injection
LETYBO® may cause serious side effects that can be life threatening. Call your healthcare
provider or get medical help right away if you have any of these problems after treatment
with LETYBO®:
• Problems swallowing, speaking, or breathing, due to weakening of associated muscles
can be severe and result in loss of life. You are at the highest risk if these problems are
pre-existing before injection. Swallowing problems may last for several months.
• Spread of toxin effects. The effect of botulinum toxin may affect areas away from the
injection site and cause serious symptoms that include loss of strength and all-over
muscle weakness, double vision, blurred vision and drooping eyelids, hoarseness or
change or loss of voice, trouble saying words clearly, loss of bladder control, trouble
breathing, and trouble swallowing.
Do not receive LETYBO® if you are allergic to any of the ingredients in LETYBO® (see Medication
Guide for ingredients); had an allergic reaction to any other botulinum toxin product such as
MYOBLOC® (rimabotulinumtoxinB), BOTOX®/BOTOX® COSMETIC (onabotulinumtoxinA),
DYSPORT® (abobotulinumtoxinA), XEOMIN® (incobotulinumtoxinA), JEUVEAU®
(prabotulinumtoxinA-xvfs), or DAXXIFY® (daxibotulinumtoxinA-lanm); or have a skin infection at
the planned injection site.
LETYBO® dosing units are not the same as, or comparable to, any other botulinum toxin
product.
Tell your healthcare provider about all your medical conditions, including side effects from
botulinum toxin products, including dry eye; breathing, swallowing, bleeding, or heart
problems; plans to have surgery; weakness of forehead muscles, drooping eyelids; have had
surgery on your face; are pregnant or breastfeeding or plan to become pregnant or breastfeed.
Tell your healthcare provider about all the medicines you take, including prescription and
over-the-counter medicines, vitamins, and herbal supplements. Using LETYBO® with certain
other medicines may cause serious side effects. Do not start any new medicines until you have
told your healthcare provider that you have received LETYBO® in the past.
Especially tell your healthcare provider if you have received any other botulinum toxin product
in the last 4 months or any in the past, and exactly which product you received (such as
MYOBLOC®, BOTOX®/BOTOX® COSMETIC, DYSPORT®, XEOMIN®, JEUVEAU®, or DAXXIFY®).
LETYBO® may cause serious side effects, including allergic reactions (such as itching, rash,
hives, wheezing, trouble breathing, or dizziness or feeling faint), heart problems (such as
irregular heartbeat and heart attack), and eye problems (including dry eye, reduced blinking,
and corneal problems). Tell your healthcare provider or get help right away if you experience a
serious side effect. No serious side events of distant spread of toxin effect associated with
dermatologic use of LETYBO® have been reported in clinical studies at the dose of 20 Units for
glabellar lines. The most common side effect of LETYBO® was headache.
These are not all the possible side effects of LETYBO®. For more information, see the full
Prescribing Information including Boxed Warning, and refer to the Medication Guide or talk
with your doctor. To report side effects associated with LETYBO®, please call 1-877-390-2906.
