Letybo® in Toronto & Markham: Next-generation Korean neuromodulator
Hugel letibotulinumtoxinA · #1 market share in Korea for 9 consecutive years · Onset in 3–5 days · Results last up to 4 months · FDA 2024 & Health Canada licensed · 1:1 unit conversion with Botox®
Quick Answer
Letybo® (letibotulinumtoxinA) is a prescription neuromodulator made by Hugel in South Korea and authorized in Canada. Like other neuromodulators, it temporarily reduces muscle activity to smooth dynamic wrinkles such as frown lines, forehead creases and crow's feet. It uses a 1:1 unit conversion with Botox®, and per unit it is about 15–25% lower in price. The toxin blocks nerve signals to targeted muscles, softening contractions. At ID Cosmetic Clinic in Markham, serving Toronto and the GTA, treatments are personally performed by physician Dr. Dan Xu, M.D., CCFP. Results typically appear within days, peak around two weeks, and last three to four months per session.

What is Letybo®?
Letybo® is a product of Korea’s Hugel Pharmaceuticals — a Type A botulinum toxin (letibotulinumtoxinA) formulation launched in Korea in 2010, with #1 market share in Korea for 9 consecutive years. 2020 received 2024 Formally received Health Canada–licensed entering the North American market as the most anticipated next-generation neuromodulator of the past decade. Its core positioning is 900 kDa complexed protein structure + 1:1 unit equivalence with Botox® + competitive per-unit pricing, making it particularly appealing to budget-conscious patients, first-time clients, and those on high-frequency maintenance schedules.
Like Botox®, Letybo® is a 900 kDa complex protein botulinum toxin type A with the same mechanism of action — blocking nerve terminals’ SNAP-25 protein and inhibiting acetylcholine release to temporarily relax the targeted muscles. Its clinical performance is nearly identical to Botox®: 3-5 days to onset (approximately 1–2 days faster than Botox®), lasts 4 months · 1:1 unit equivalence conversion (far more straightforward than Dysport®’s 1:2.5 conversion).
Letybo’s true differentiator lies in cost-effectiveness and brand options: ① per-unit pricing is 15–25% lower than Botox® (consultation-based pricing/U); ② over 10 years of high-volume clinical data in Korea (9 consecutive years as the #1 market-share brand means tens of millions of doses administered annually); ③ the Korean clinic philosophy of “natural, subtle enhancement” is carried directly into our treatment protocols. Dr. Xu designates Letybo® as the preferred formulation for budget-conscious patients, first-time users, patients on high-volume annual maintenance, and those with a K-beauty preference.

Letybo comparison with other neurotoxins
| brand | Onset | Maintenance | Dosage conversion |
|---|---|---|---|
| Letybo® | 3-5 days | 4 months | 1:1 vs Botox |
| Botox® | 3-7 days | 4-6 months | Benchmark |
| Dysport® | 2-5 days | 3-5 months | 1:2.5 vs Botox |
| Xeomin® | 5-7 days | 3-4 months | 1:1 vs Botox |
Note: Letybo® is a Korean brand that entered the North American market in 2024. Its clinical profile is comparable to Botox®, but at a more accessible price point — making it the preferred choice for budget-conscious clients and those requiring frequent maintenance.
How Letybo® Works
Letybo® shares the same molecular mechanism as Botox® — blocking the SNAP-25 protein — with a very similar clinical onset curve. However, given the distinct injection philosophy of Korean clinics, Dr. Xu applies specific “Korean natural-look aesthetic” protocol adjustments in dosing and injection point placement.
Consultation & goal setting
Dr. Xu assesses your muscle activity by asking you to perform facial expressions (raising your brows, frowning, smiling, pursing your lips), evaluating dynamic muscle strength and residual static lines, and clearly establishes whether the goal is to “soften movement” or “completely stop expression” — Letybo®’s dosing philosophy favors the former.
Customized dosing (1:1 unit equivalence with Botox®)
Letybo and Botox® have a 1:1 unit equivalence conversion (previous Botox® 20U for glabellar lines → Letybo® 20U), so the conversion is straightforward. Dr. Xu determines the final dosage based on your individual muscle strength and facial symmetry; Korean clinics typically follow a slightly lower-dose philosophy — 10–15% lower than standard North American protocols, with a greater focus on natural results.
Precise multi-point superficial injection technique
A fine 30–32G needle is used to deliver multiple shallow injections along the natural muscle grain. Letybo®’s diffusion profile is similar to Botox® (moderate) — sitting between Xeomin® and Dysport®. The entire process takes 5–10 minutes, with minimal discomfort (comparable to a small insect bite).
3-5 days to onset
Letybo’s onset is approximately 1–2 days faster than Botox® — a feeling of muscle heaviness typically begins around Day 3–5, with full effect reached by Day 10–14. Do not self-administer additional doses if results seem minimal in the first week — allow the formulation sufficient time to bind to nerve terminals. Letybo®’s onset curve is best described as “fast but smooth” among the four major brands.
4 month maintenance period
A first injection typically lasts 4 months, comparable to Botox®. Long-term users should be mindful of antibody avoidance strategies — like Botox®, Letybo® carries a complexed protein structure, placing antibody risk in the low-to-moderate range. Dr. Xu recommends switching to Xeomin® at least once per year to reduce cumulative antibody exposure.
Cost-effectiveness & long-term antibody management — Dr. Xu’s three-line strategy
Letybo’s two key clinical advantages are competitive per-unit pricing and 1:1 Botox unit equivalence conversion; however, long-term use still requires planning around antibody risk. Dr. Xu addresses this through three key strategies to maximize both cost-effectiveness and safety.
Korean dosing philosophy
Dr. Xu follows the “conservative start” dosing protocol used in Hugel’s Korean clinics — approximately 10–15% lower than standard North American doses — prioritizing natural, subtle enhancement over a frozen appearance.
12-week interval guidelines
Regardless of the neurotoxin brand, Dr. Xu maintains a minimum 12-week interval between injections to prevent the immune system from forming antibodies through excessive exposure.
Annual brand rotation
Patients who maintain treatments at high frequency are advised to switch to Xeomin® (the “bare molecule” toxin) at least once per year to reduce cumulative antigen exposure, keeping Letybo® as their long-term primary choice.
Among my 80,000 treatment areas, Letybo® has seen the fastest patient growth over the past 12 months — driven partly by the excitement around its FDA 2024 approval, and partly by the fact that per-unit pricing 15–25% lower than Botox® translates to a genuine 20–30% cost saving for high-volume annual maintenance patients. My position on Korean brands has always been consistent: translating 14 years of refined Korean clinic protocols to Canada — rather than defaulting to the North American “high-dose” approach. — Dr. Dan Xu, M.D., CCFP · Hugel Certified Letybo Injector
Am I a Candidate for Letybo®?
You are welcome to do a preliminary self-assessment before your consultation, but suitability can only be confirmed by Dr. Xu through dynamic muscle assessment + prior neurotoxin history review + budget planning. Based on a comprehensive clinical assessment — particularly for budget-conscious clients, first-time patients, those drawn to the Korean aesthetic, or those requiring high-volume annual maintenance — Letybo® is often the optimal choice.
You may be a candidate for treatment if…
- First-time aesthetic treatment seekers who are budget-conscious and value-driven
- Clients who plan high-volume annual maintenance (200U+ / year) and are looking to reduce costs
- Clients who prefer the Korean aesthetic / “natural subtle enhancement” style
- Clients with dynamic wrinkles (glabellar lines / forehead lines / crow’s feet)
- First-time patients who prefer to start with a mainstream brand to gauge their response
- Clients who want faster onset (3–5 days) but wish to avoid Dysport®’s wider diffusion spread
- Clients seeking masseter slimming / square face improvement (high-unit treatment)
- Clients looking for a Botox / Xeomin rotation option during the interval period
Treatment is not recommended if any of the following apply…
- Pregnancy or breastfeeding
- Neuromuscular disorders (myasthenia gravis, Lambert-Eaton syndrome, ALS)
- Active infection or inflammation at the injection site
- Allergy to letibotulinumtoxinA or human serum albumin
- Currently taking aminoglycoside antibiotics
- Received another neuromodulator brand within the past 3 months
- Have developed antibodies to complexing proteins (Xeomin® recommended)
- Clients with unrealistic expectations or those seeking a completely frozen face (not recommended for Asian faces)
Clinical Scenario × Neuromodulator Brand — Dr. Xu’s Recommendation Guide
Dr. Xu has clear brand preferences for different clinical scenarios — Letybo® is the first choice for budget-conscious patients, first-time neuromodulator users, and those requiring high-volume annual maintenance:
| Clinical context | First choice | Secondary option | Reason |
|---|---|---|---|
| Budget-conscious / cost-effective | Letybo | Dysport | Per-unit cost 15–25% lower than Botox® |
| high-volume annual maintenance | Letybo | Xeomin | 1:1 Unit conversion + competitive per-unit pricing |
| Korean aesthetic medicine preference | Letybo | Botox | #1 market share in Korea for 9 years |
| First-time injection patients | Botox | Letybo | the most extensive clinical data |
| Rapid onset before a wedding | Dysport | Letybo | 2-5 days to onset |
| Long-term maintenance (5+ years) | Xeomin | Letybo | Lowest antibody risk |
| Masseter slimming (high-unit treatment) | Letybo / Botox | Dysport | 1:1 unit conversion + competitive per-unit pricing |
Letybo® Treatment Planning
Letybo neurotoxin treatment is a physician-tailored procedure. Dr. Xu designs a 4-month cyclic maintenance plan. For patients requiring high-volume annual maintenance, it is recommended to maintain regular intervals of 12 weeks or more, minimizing the risk of antibody formation, with a mid-year switch to Xeomin® recommended to reduce cumulative antigen exposure.
Initial consultation and goal assessment
A free 30-minute consultation includes dynamic expression assessment, review of prior neurotoxin history, allergy screening, and an explanation of the “Korean natural look” philosophy.
Customized dosing (1:1 Botox® conversion)
Dr. Xu converts your previous Botox® dosage to Letybo® on a 1:1 unit basis (glabellar lines 20U / crow’s feet bilateral 16–24U / forehead lines 12–16U), starting conservatively on the first treatment.
D14 Follow-up refinement
D14 is the assessment window for Letybo®’s full effect. Dr. Xu evaluates symmetry and coverage, and if needed, performs a 5–10 U touch-up (complimentary for first-time treatments).
4-month maintenance cycle
We recommend scheduling your maintenance injection when results have diminished by approximately 70% — rather than waiting for full wear-off. For patients receiving high-volume treatments annually, substituting one session with Xeomin® is advised to minimize antibody risk.
Typical treatment cycle timeline
Below is the standard timeline for Letybo® clients, from initial consultation through the maintenance period:
| Treatment timeline | Contents |
|---|---|
| Day 0 | Free 30-Minute Consultation (dynamic muscle assessment + neuromodulator treatment history + budget and goals discussion) |
| Day 0 (injection day) | Injection may be performed immediately following consultation · Entire procedure takes 5–10 minutes |
| D3-D5 | Initial effect visible · Muscles begin to feel heavier |
| D10-D14 | Full effect reached · Dynamic wrinkles visibly reduced |
| D14 Follow-up | Symmetry and coverage assessment · Touch-up of 5–10U if needed (complimentary at first visit) |
| Month 4 | Results diminished by 50–70% · Entering the maintenance injection window |
| 3 times per year | Minimum 12-week intervals maintained consistently · One mid-cycle switch to Xeomin® recommended for rotation |
Exact units and treatment intervals are customized by Dr. Xu at consultation, based on your muscle strength, treatment area, and budget.
Indications treatable with Letybo®
Letybo® delivers consistent results for dynamic wrinkles, masseter reduction, and high-unit treatment areas. For the concerns most common in Asian faces — glabellar lines, crow’s feet, forehead lines, masseter hypertrophy, and facial contouring — Dr. Xu has developed dosing protocols equivalent to Botox® (1:1 unit conversion).
Glabellar lines (“11” lines)
For dynamic contraction of the corrugator supercilii and depressor supercilii muscles, Letybo® at 20 U is the FDA- andDynamic wrinkles Over 80% improvement, using the standard 5-point injection technique.
20U / Every 4 monthsForehead lines
For dynamic horizontal forehead lines caused by frontalis muscle contraction, Letybo® at 12–20 U performs exceptionally well on mid-sized foreheads. Its moderate diffusion profile is ideal for Korean-style subtle refinement that preserves a natural degree of brow elevation.
12-20U / Every 4 monthsCrow’s feet
For dynamic contraction of the lateral orbicularis oculi, Letybo® at 8–12 U per side allows precise diffusion control, preserving the natural smile lines at the outer corners of the eyes — the hallmark of the Korean aesthetic: natural, understated results.
Bilateral 16–24U / every 4 monthsMasseter slimming (square face)
This is one of the most requested treatments among Asian women. For masseter hypertrophy, bilateral injections of 30–50 U Letybo® per side effectively reduce muscle volume, and the 1:1 Botox unit conversion + competitive per-unit pricing make high-unit masseter treatments more cost-effective.
Bilateral 60–100U / every 4–6 monthsBrow Lift
Selectively relaxing the brow depressor muscles produces a subtle lift in brow position. Letybo® is administered at a precise micro-dose of 4–10U to avoid an overly arched, “surprised” appearance — the Korean aesthetic philosophy favors a gentle brow lift rather than a dramatic elevation.
4-10U / Every 4 monthsTrapezius slimming (shoulder contouring)
For trapezius hypertrophy causing a bulky shoulder-neck profile, Letybo® at 50–100 U per side can create a slimmer, more elongated “swan neck” contour — one of the signature treatments in the Korean aesthetic philosophy.
Bilateral 100–200 U / every 4–6 monthsGummy smile
Overactive levator labii superioris alaeque nasi (LLSAN) causes excessive gum exposure when smiling. Letybo® precisely targets the LLSAN muscle at 2–4 U per side, producing a natural smile curve with diffusion control comparable to Botox®.
4-8U / Every 4 monthsNeck rejuvenation (Nefertiti Lift)
Platysmal banding: Letybo® administered along the bands at 40–60 U can soften the cords and provide a mild lift to the jawline. The combination of high-unit requirements and competitive per-unit pricing makes Letybo® particularly well suited for this indication.

Letybo® is not a “cheap alternative to Botox®” — rather, a combination of Korea’s #1 brand + 1:1 unit equivalence + genuine value
Like Botox®, Letybo® is a 900 kDa complex-protein botulinum toxin type A with an identical mechanism of action — but with nine consecutive years as the #1 market-share holder in Korea and the real-world clinical refinement that comes with it, plus 1:1 Botox unit-for-unit conversion + 15–25% lower cost per unit than Botox®, making it a clinically compelling option for budget-conscious clients, first-time patients, and those requiring high-volume annual maintenance.
As a Hugel Canada certified injection physician, Dr. Xu will tailor the treatment through personalized decision-making based on your budget, injection history, onset expectations, and long-term goals. Letybo®’s true value is not about “replacing another brand” — it is about making your long-term neurotoxin maintenance plan more sustainable without compromising quality.
Letybo® Pricing: How It Compares with Botox®
Pricing is based on units (U). Per unit, Letybo® is the most cost-effective among the four major brands — approximately 15–25% lower than Botox®. Following a Free 30-Minute Consultation, Dr. Xu will customize your unit dosage and provide a personalized quote. Note: Letybo® and Botox® share a 1:1 unit conversion — your existing Botox® dosage can be transferred directly. Savings are especially significant for high-unit treatments (masseter / trapezius).

Common Risks · Contraindications · Safety Protocol
Transparency in medical aesthetics is itself a marker of trustworthiness. We openly share all possible reactions, serious risks, contraindications, and absolute exclusions so you are fully informed before your consultation. Before every injection, Dr. Xu reviews Letybo®’s risk profile and long-term planning strategy with you, point by point.
Common reactions (may occur shortly after injection)
- Mild redness, swelling, or small bumps at injection points (30 minutes to 2 hours to resolve)
- bruising (5-7 days to resolve naturally; Arnica may be used to speed recovery)
- Feeling of tightness or heaviness in the head (D1-D5 common; gradually resolves with time)
- Mild headache (24-48 hours; acetaminophen may be taken for relief)
- Mild soreness or pressure at the injection site (Mild chewing weakness in the 1–2 weeks following masseter injection is normal)
Serious risks (rare, but must be disclosed)
- Eyelid ptosis (upper eyelid droop) — Most commonly seen when glabellar injections diffuse to the levator palpebrae superioris; Dr. Xu reduces this risk to <1% through precise injection point spacing. If it occurs, it typically resolves on its own within 4–6 weeks; Apraclonidine eye drops can be used to speed recovery.
- Lateral brow ptosis / facial expression asymmetry — Letybo has moderate diffusion; this is occasionally noted in Asian women with thinner mimetic muscles. A day-14 follow-up allows a 5–10 U touch-up to refine symmetry if needed.
- Unnatural smile — Diffusion into the zygomaticus major during crow’s feet injection; Dr. Xu avoids this by maintaining a distance of 1.5 cm or more from the lateral canthus.
- allergic reaction — Extremely rare (Letybo® excipients contain human serum albumin); patients with known allergies must disclose prior to treatment.
- Antibody formation (treatment failure) — Letybo antibody risk: low to moderate. For high-frequency annual users, incorporating one Xeomin® session mid-cycle is recommended to reduce cumulative antigen exposure.
- Infection at the injection site — Extremely rare; preventable with proper sterile technique
Absolute contraindications (do not treat)
- Pregnancy / breastfeeding
- Neuromuscular disorders (myasthenia gravis, Lambert-Eaton syndrome, ALS, multiple sclerosis)
- Active infection or inflammation at the injection site
- Severe allergy to letibotulinumtoxinA or human serum albumin
- Currently taking aminoglycoside antibiotics (e.g., gentamicin, which potentiates toxin activity)
- Injection of another neurotoxin brand within the past 3 months (to avoid compounding antibody exposure)
- Unrealistic expectations (e.g., requesting a completely frozen face or absolute symmetry)
- Active depression, anxiety, or emotional instability (we recommend stabilizing your mental health before proceeding)
Safety protocols strictly enforced by Dr. Xu
- Every patient undergoes a dynamic muscle assessment, review of prior neurotoxin history, and long-term treatment planning discussion before each injection.
- Written informed consent form signed before every injection, with detailed unit records kept on file.
- All injections are spaced a minimum of 12 weeks apart (to reduce antibody formation)
- All Letybo® injections are performed personally by Dr. Dan Xu, M.D. — never delegated to a technician
- Mandatory D14 follow-up to assess symmetry · Complimentary touch-up at first visit
- Cumulative unit documentation maintained · Ongoing tracking of onset and fading signals
- Letybo product sourced through Hugel’s Canadian domestic cold chain · Maintained at 2–8°C throughout
Frequently Asked Questions About Letybo® in Toronto
Answered personally by Dr. Dan Xu — based on the most frequently asked questions from patients in Toronto and Markham.How Is Neurotoxin Treatment Priced? Why Do Costs Vary So Much Between Clinics?
The difference in pricing does not come from the device or product itself — it comes from the depth of assessment. The appropriate dosage, injection points, combination strategy, and whether a multi-modality plan is needed for neuromodulator treatment can only be determined through a physician consultation — this cannot be assessed from a standard price list alone.
Routine, straightforward cases can be carried out by our trained medical team following Dr. Xu's protocols, making them more accessible. Complex cases, those with special contraindications, or revision cases require Dr. Xu's direct involvement throughout — and pricing reflects that level of medical resource. For all injectable treatments, we insist on physician-performed injections. For laser and energy-based treatments, the price difference comes down to the clinical experience gap between physician-performed and technician-performed procedures (physician vs. technician). Treatment plans and costs are determined by your clinical needs — not by a price list. First-visit clients receive a complimentary 30-minute consultation and assessment, at which Dr. Xu will discuss specifics with you based on the evaluation findings.
