Too many botulinum toxin brands to choose from – worried about wasting money on poor results, or ending up with cheap counterfeit products? Korean botulinum toxin is actually on par with premium imported brands – Letybo offers great value for first‑timers, Nabota has triple‑certified high purity for long‑term maintenance, and Botulax is known for its long‑lasting effect and stable reputation. After reading this, you’ll know which brand better suits your needs and budget.
Botulinum Toxin is a nerve conduction blocker that inhibits the release of acetylcholine from nerve endings, blocking signals to muscles and temporarily relaxing overactive muscles. In Korean aesthetic medicine, Type A botulinum toxin is widely used to smooth dynamic wrinkles – such as forehead lines, glabellar lines, and crow’s feet – as well as to slim the face by relaxing the masseter muscle. Its core mechanism can be summarised as: Precise blocking → Muscle relaxation → Wrinkle reduction / Contour enhancement.
Suitable candidates: Those with prominent dynamic lines due to expressive facial movements; those with masseter hypertrophy seeking a slimmer square jaw contour; those wanting to refine shoulder lines by relaxing the trapezius muscle; and those suffering from hyperhidrosis. The optimal age range is typically 25‑55, especially for younger individuals (Millennials & Gen Z) trying non‑surgical anti‑ageing for the first time.
Absolute contraindications: Allergy to botulinum toxin components; active infection or inflammation at the injection site; neuromuscular disorders (e.g., myasthenia gravis); pregnancy and breastfeeding. Those with bleeding disorders or taking anticoagulant medication should inform the doctor beforehand.
Korea is one of the world’s core production hubs for botulinum toxin, with fierce competition among local brands. They differ in purity, diffusion, and duration. Below is a comparison of mainstream Korean botulinum toxin brands at Gangnam dermatology clinics in 2026:
| Brand (Korean / English) | Manufacturer | Key Features | Indications | Duration | Reference Price (KRW) |
|---|---|---|---|---|---|
| Letybo (White) | Hugel (Korea) | No.1 market share in Korea; first Asian brand with US FDA approval; natural, smooth results; cost‑effective | Glabellar lines, forehead lines, crow’s feet, masseter slimming | 3‑6 months | ₩250,000 – 450,000 / 100U |
| Nabota (Green / Rainbow) | Daewoong (Korea) | Triple‑certified (FDA, EMA, TFDA); purity up to 99.9%, low immunogenicity | Glabellar lines, forehead lines, crow’s feet, shoulder slimming, calf slimming | 5‑6 months | ₩300,000 – 500,000 / 100U |
| Neuronox (Pink) | Medytox (Korea) | KFDA‑approved; used in over 30 countries; high purity, fast onset | Facial wrinkles, square jaw, facial lifting, calf slimming | 4‑6 months | ₩220,000 – 400,000 / 100U |
| Botulax (White / exported as Letybo) | Hugel (Korea) | Strong domestic sales; excellent stability; the only Korean botulinum toxin simultaneously sold in the US, China, and Europe | Glabellar lines, nasolabial folds, periorbital wrinkles | 3‑6 months | ₩200,000 – 380,000 / 100U |
| RenTox (Red) | Rejuran (Korea) | Labeled 100U but contains 120U; animal‑free ingredients; can be stored at room temperature for over one month | Crow’s feet, glabellar lines | 4‑5 months | ₩280,000 – 480,000 / 100U |
Selection advice: If you prioritise cost‑effectiveness and are a first‑timer, Letybo and Botulax are good choices. If you are concerned about antibody formation or need long‑term regular injections, Nabota‘s high purity formula is advantageous. For delicate areas (e.g., periorbital), choose a brand with low diffusion such as Letybo or Nabota.
Step 1 – Consultation: The Gangnam dermatologist assesses facial muscle activity to determine injection points and dosage.
Step 2 – Preparation: Cleanse the injection area; topical anaesthetic may be applied to enhance comfort if needed.
Step 3 – Precision injection: Using an ultra‑fine needle, the toxin is precisely injected into the target muscles. A single session typically takes 5‑15 minutes. Sensation is mainly a mild pinprick, well within most people’s pain tolerance.
Step 4 – Post‑care observation: Stay at the clinic for 10‑15 minutes of observation; the doctor provides aftercare instructions, such as not lying flat for 4 hours and avoiding strenuous exercise for 24 hours.
Immediate effect: Results begin to appear at 3‑7 days after injection, with dynamic wrinkles gradually fading. Nabota and RenTox have a relatively faster onset.
Progressive effect: Peak effect is reached at 2‑4 weeks, with full muscle relaxation. Muscle volume reduction effects (face slimming, shoulder slimming, calf slimming) become more noticeable at 1‑2 months.
Duration: Typically 3‑6 months, depending on the brand, individual metabolism, and dosage. Nabota and Botulax are known for relatively longer duration among similar products. Regular maintenance every 4‑6 months is recommended to sustain the desired effect.
Q1: Does the injection hurt?
A: The pain is very mild – most describe it as a mosquito bite. Korean dermatology clinics use ultra‑fine needles and may apply topical anaesthetic before injection, making the overall experience quite comfortable.
Q2: How soon will I see results? How long do they last?
A: Results typically start at 3‑7 days after injection, with full effect at about 2 weeks. Duration ranges from 3‑6 months, varying by brand and individual metabolism. Nabota and Botulax tend to have a relatively longer duration.
Q3: What is the difference between Korean brands and Botox (Allergan)?
A: The core ingredient is the same – Botulinum Toxin Type A. Differences lie in excipients, purity, and diffusion. Korean brands like Letybo and Nabota offer better cost‑effectiveness, and multiple studies show no significant difference in efficacy and safety compared to Botox.
Q4: How much does Korean botulinum toxin cost?
A: In 2026 Gangnam, the price for 100 units (100U) of Korean brands ranges from ₩200,000 to ₩500,000. Single‑area wrinkle treatments can be as low as ₩25,000‑55,000, and masseter slimming (50U) ranges from ₩29,000‑121,000. Exact prices vary by brand, clinic, and promotions.
Q5: Which dermatology clinics in Korea are good for botulinum toxin injections?
A: Seoul Gangnam has many experienced certified dermatologists. Choose a KFDA‑approved clinic, confirm the product is genuine, and ensure the procedure is performed by an experienced physician.
Common side effects: Temporary redness, bruising, and mild swelling at the injection site – usually resolve within 24‑72 hours. In rare cases, headache or eyelid ptosis may occur, often related to injection technique.
Rational advice: Botulinum toxin is a prescription drug that must be administered at a licensed clinic by a qualified physician. Never choose unauthorised channels or self‑inject due to lower prices. Before treatment, confirm that the product packaging is intact, with clear KFDA certification marks, and be honest about your medical history and medications. Beauty begins with Safety First.
