Korean Botox Brands Explained: Botulax, Nabota, Xeomin and Allergan

Botulax, Nabota, Xeomin and Allergan's Botox are all botulinum toxin type A products that relax muscles in the same basic way, and in experienced hands they can all give good results for wrinkles, jaw slimming and other cosmetic uses. The main differences are where they are made, how they are purified, how widely they are approved around the world and how much long-term published data supports them. Botox (Allergan) has the longest track record, Xeomin is known for removing the complexing proteins around the toxin, and Botulax and Nabota are Korean-made products that are widely used in Korea and several other markets. Doctor skill and correct dosing usually matter more than the brand.

Why there are so many brands in Korea

Korea has a large domestic botulinum toxin industry, and several local manufacturers produce products approved by Korean regulators. Because these products are readily available locally, they are commonly used in Korean clinics alongside imported brands. For visitors, this means you may be offered a choice of toxins, and it helps to understand what you are choosing between.

Allergan Botox (onabotulinumtoxinA)

• Origin: made by Allergan (now part of AbbVie) in the United States and Ireland.
• Track record: the first botulinum toxin approved for cosmetic use in many countries, with decades of clinical research and real-world experience.
• Formulation: contains the toxin together with complexing proteins.
• Use: often regarded as the reference product against which others are compared.

Xeomin (incobotulinumtoxinA)

• Origin: made by Merz in Germany.
• Formulation: sometimes called a "naked" or "pure" toxin because the complexing proteins are removed during manufacturing.
• Possible advantage: it is theorised that fewer extra proteins may reduce the chance of the immune system forming neutralising antibodies. This is plausible, but evidence that it makes a meaningful difference for most cosmetic patients is limited.
• Storage: unopened vials can be stored at room temperature, which is a practical advantage for clinics.

Botulax (letibotulinumtoxinA)

• Origin: made by Hugel in Korea.
• Formulation: contains the toxin with complexing proteins, similar in structure to Botox.
• Approval: approved in Korea and a number of other countries. A version of the same toxin has also gained approval in the United States and Europe under a different name.
• Use in Korea: one of the most widely used toxins in Korean clinics.

Nabota (prabotulinumtoxinA)

• Origin: made by Daewoong in Korea.
• Formulation: purified using a proprietary process. It is also sold in the United States and Europe under different names.
• Studies: it has undergone clinical trials comparing it with Botox for frown lines, with broadly comparable results reported in those trials.
• Use in Korea: widely available and commonly used for wrinkles and jaw treatments.

How they compare in practice

For most people, the experience with each product is similar:

1. Onset: effects usually begin within a few days and peak around two weeks. Some patients and doctors report small differences in onset speed between brands, but this varies.
2. Duration: typically around three to four months for facial wrinkles with any of these products at appropriate doses.
3. Units: Botox, Xeomin, Botulax and Nabota are often used at roughly similar unit numbers, but they are separate products and units are not officially interchangeable. Dysport, another brand, uses a different scale altogether.
4. Side effects: similar profiles, including bruising, headache and, occasionally, eyelid or brow drooping.

Head-to-head research comparing all of these products directly is limited, so claims that one is clearly "stronger" or "longer lasting" should be treated with caution.

Antibodies and resistance

A small number of people develop antibodies that reduce their response to botulinum toxin. Risk factors are thought to include high cumulative doses and frequent top-ups at short intervals. Some doctors prefer products with fewer complexing proteins, such as Xeomin, for patients who need high doses or who have had reduced responses in the past. If you are a regular patient, using sensible intervals and the lowest effective dose is considered more important than the brand alone.

How to choose

• Ask which products are available and whether they are officially approved in Korea.
• Ask why your doctor recommends a particular product for your area and goals.
• If you have used a toxin before with good results, share the brand and dose.
• Request a written record of the product name and units so your doctor at home can continue care.
• Be cautious of unusually low offers or unknown brands that are not approved, as quality and authenticity matter.

Frequently asked questions

Are Korean toxins as safe as Botox?

Products approved by Korean regulators have undergone safety evaluation, and several are also approved in other major markets. As with any toxin, safety depends heavily on correct handling, dosing and injection technique.

Can I switch brands between treatments?

Yes, many people do. Your doctor may adjust the dose when switching, and results can feel slightly different.

Which brand lasts the longest?

There is no consistent evidence that one of these brands lasts clearly longer for most people. Dose, area and individual response have a larger effect.

Discuss the options with your doctor

All four products can work well when used appropriately. A qualified dermatologist can explain which product they use and why, tailor the dose to your muscles, and help you keep consistent records if you receive treatment in more than one country.
