Botox Brands in Korea: Coretox, Xeomin and BOTOX Compared

Hi, I’m Dr. Youro. If you are booking Botox in Korea, the menu can be confusing: Coretox, Xeomin, BOTOX, Dysport and several different prices.

A brand’s country of origin is not a quality ranking. Compare the exact product, its formulation, the dose for your treatment area and your previous response.

This guide explains the differences that matter when choosing a treatment in Korea.

1. Which Botox brands will you see in Korea?

Clinics often use “Botox” as a general name for botulinum toxin injections. BOTOX is also a specific Allergan brand. The products below all use botulinum toxin type A, but their formulations and potency units are not identical.

Countries identify the company or brand origin, not necessarily the manufacturing site. Korean clinics may call Xeomin and BOTOX “imported” because they are imported into South Korea. This is not a worldwide product category.

BOTOX is the original product with the first US approval in 1989. That initial approval was for eye muscle disorders; cosmetic approval for frown lines followed in 2002. This history does not mean every other product is a counterfeit.

Botulax is associated with the overseas brand name Letybo. Brand names, packaging and approved uses vary by market, so ask for the exact product being used in Korea rather than assuming it matches the label at home.

All these type A toxins reduce the release of a nerve messenger called acetylcholine, temporarily weakening the treated muscle. For the mechanism and the difference between muscle, skin and salivary gland injections, see How Botox Works.

2. Does brand origin affect strength or duration?

A higher price or a foreign brand does not, by itself, mean a stronger or longer-lasting result. The treatment area, dose, injection placement and your own response matter.

In a randomized frown-line trial, Xeomin and BOTOX were each given at 20 U. At day 30, 92.5% and 95.1% of assessed participants, respectively, had no or mild lines at maximum frown. Xeomin met the study’s predefined noninferiority criterion. This supports that particular comparison, not equal duration in every muscle. The study was supported by Merz. [1]

For a return visit, bring the product name, dose, treatment date and photographs from your previous session. Your own treatment record is more useful than choosing a country label.

3. Xeomin vs Coretox: what does removing proteins mean?

The active part is a 150 kDa neurotoxin protein. Complexing proteins are additional proteins associated with it; they are not the part that produces muscle relaxation.

Xeomin comes from Germany’s Merz; Coretox comes from South Korea’s Medytox. Both remove complexing proteins. If you receive repeated, higher-dose treatments and are concerned about resistance, these are two products to discuss. Their shared feature is the formulation, not the country.

Removing these proteins reduces exposure to additional bacterial proteins. It does not make the product automatically stronger, and it does not establish that Xeomin and Coretox have identical clinical performance. [2] Coretox product information

Antibody-related resistance is uncommon in cosmetic treatment. A product containing complexing proteins does not inevitably cause resistance.

In an analysis of BOTOX trials across cosmetic and medical uses, 27 of 5,876 people (0.5%) developed neutralizing antibodies. Five were classified as secondary nonresponders. This AbbVie-supported analysis is not a lifetime risk estimate for every brand or a cosmetic-only population. [3]

Protein removal does not reduce the risk to zero. Appropriate dosing, treatment intervals and avoiding unnecessary booster injections also matter. A disappointing result can reflect dose or muscle selection rather than antibodies. Switching brands alone is not a guaranteed solution to established resistance. [2]

4. Why 50 units of Dysport is not 50 units of BOTOX

Units measure biological potency using product-specific tests. Do not compare brands by the unit number alone.

For example, a frown-line trial compared Dysport 50 U with BOTOX 20 U. Dysport met the trial’s noninferiority criterion at day 29. That is a study-specific comparison, not a universal conversion formula for the jaw, forehead or other areas. The trial was supported by Ipsen. [4]

When comparing quotes, ask: “Which product, how many of that product’s units, and which muscles are included?” A lower price per unit does not necessarily mean a lower price for an appropriate treatment.

5. How much does Botox cost in Korea?

Here are indicative three-area wrinkle-treatment prices discussed in my Korean article. They are a budgeting reference, not a verified national average or a current clinic quotation.

Reference: Dr. Youro’s Korean comparison, November 2026. Promotional offers and included areas vary. Confirm the final quote before booking.

Ask the clinic to list the brand, areas, units, VAT, consultation charge and review or adjustment policy. “Three areas” is a package description, not a standardized dose. Use the final KRW total when comparing clinics; your card’s exchange rate and fees affect the amount charged at home.

6. Which product should you discuss?

• First treatment, cost is the priority: compare Korean options such as HiTox or Botulax, together with the injector’s plan and follow-up arrangements.
• Repeated higher-dose treatment, concerned about resistance: discuss protein-free formulations such as Coretox or Xeomin.
• Happy with previous Dysport treatment: discuss continuing the same product and bring your previous dose record.
• You value the original brand’s long clinical history: discuss BOTOX, without assuming the higher price guarantees a better result.

No brand replaces a well-planned treatment. Tell the clinician how much movement you want to retain, what bothered you after earlier injections and what result you hope to achieve.

7. What should visitors to Korea arrange?

• Before booking: confirm who will inject, whether consultation is available in a language you understand, and the exact product and treatment scope.
• Plan a review: results develop after the appointment. Ask when your specific treatment should be assessed and whether that fits your departure date. A short visit does not justify an early extra dose.
• Keep a treatment record: request the brand, dose by area, date and clinic contact details for your clinician at home.
• Arrange aftercare: know how to contact the clinic from overseas and who will assess a problem after you leave.

Possible adverse effects include bruising, pain, asymmetry and eyelid or brow drooping. Discuss previous reactions, neuromuscular conditions, medicines, pregnancy and breastfeeding before treatment. Seek urgent medical help for difficulty breathing, swallowing or speaking after an injection. Official BOTOX Cosmetic safety information

Quick answers

Is Korean Botox weaker?
Country alone does not establish potency or clinical quality. Compare the exact product and treatment plan.

Are Xeomin and Coretox resistance-proof?
No. Both remove complexing proteins, but antibodies can target the active toxin itself.

Does “original Botox” mean other brands are fake?
No. It refers to BOTOX’s original approval history. Other named toxin products are separate brands; authenticity must be checked for the actual product supplied.

What matters most when choosing?
The formulation, your previous response, appropriate dose and placement, and a clear follow-up plan.
