Korean Botox vs American Botox: What Is Actually Different
On this page
I'm Dr. Jong Seon Kim, a plastic surgeon at Gangnam HERA in Seoul and a board member of the International Petit Medical Society, and most of my clinical day is spent on fillers and injectables. When I send an estimate that lists two toxin options side by side, the reply is almost always the same: "Is the Korean botox as good as the American one, or is it a cheaper copy?" The short answer is that neither is a copy. Korean toxins and the original American brand are all botulinum toxin type A, and they relax the targeted muscle in the same way. What differs is who makes them, how they are formulated, how long they have been studied and where they sit on the estimate. For most patients the right choice depends on their own history β not on the flag on the box.
What do people mean by "Korean botox" and "American botox"?
"American botox" almost always means Allergan Botox, the original brand; "Korean botox" means toxins made in Korea β at HERA, Coretox and Newlux. "Botox" began as one brand name and has become an everyday word for any botulinum toxin, which is where most of the confusion starts.
At HERA we use four products. Allergan Botox (onabotulinumtoxinA) was developed by Allergan, now part of AbbVie. Coretox is made by Medytox in Korea, and Newlux by Newmeco, a Medytox affiliate, at Medytox's plant. The fourth, Xeomin, is made by Merz in Germany β so the real choice in our clinic is not simply Korea against America.
Do Korean and American botox work differently?
No β all four temporarily relax the muscle they are injected into, by the same type A mechanism, and at HERA they are used for the same areas with the same timeline. Those areas are forehead lines, frown lines, crow's feet, jaw slimming (masseter), the shoulder line (trapezius) and underarm sweating.
The timeline is also shared. Most people notice the effect within 3~7 days, the full result is usually visible at around two weeks, and it generally lasts about 3~4 months before fading gradually. Results vary from person to person. The dose, the area and your own metabolism move those numbers more than the brand does.
What is actually different between them?
The maker, the formulation and the length of the clinical record β not the way they work.
| Product | Origin | Formulation | Known for |
|---|---|---|---|
| Allergan Botox | Allergan (AbbVie) | The original type A toxin | First approved for cosmetic use; the most extensively studied brand |
| Xeomin | Merz, Germany | Complexing proteins removed, leaving essentially only the active neurotoxin | A purified, "naked" toxin |
| Coretox | Medytox, Korea | Complexing-protein-free; no animal-derived components in the culture medium and no human serum albumin as a stabiliser | A refined "core" toxin |
| Newlux | Newmeco, Korea | Made without animal-derived components in its raw-material process; approved by Korea's Ministry of Food and Drug Safety | A value Korean option |
One practical point people miss: units are not directly interchangeable between brands. A dose that is right in one product is not automatically the same number in another, which is why I plan by the muscle, not by a unit count copied from a previous clinic.
Does "complexing-protein-free" matter for you?
It matters most if you expect to have toxin regularly for years; for a first treatment it is rarely the deciding factor. Complexing proteins are accessory proteins that sit around the active toxin. Xeomin and Coretox are manufactured without them, which is associated with a lower theoretical risk of the body forming antibodies that blunt the effect over repeated treatments.
I use the word "theoretical" on purpose. It is a sensible reason for frequent users β someone treating a strong jaw muscle every few months, for example β to consider those two products. It is not a reason to worry if you have had the original brand before and it worked well for you.
Why is the Korean option usually the lower line on the estimate?
Because it is made domestically and positioned as a value option, not because it is a weaker product. Newlux in particular is positioned as an accessible Korean toxin with the familiar wrinkle-softening and muscle-slimming effects of type A toxins.
I don't publish prices, and I have explained why in how much botox costs in Korea. What I can say is that the product is one line on your itemised written estimate, so you see the difference between options before you decide. For treatments that are repeated often, that difference adds up β which is why the brand question comes up most in masseter botox pricing.
How do I choose between them for you?
I start with your history and your goal, then choose the product β not the other way round.
- First treatment, and you want the most-studied brand: Allergan Botox is a familiar, well-documented starting point.
- You have toxin often, or you want to minimise resistance risk: Xeomin or Coretox.
- Regular maintenance where value matters: a Korean product such as Newlux or Coretox.
- A previous treatment seemed to wear off quickly: tell me the product, the dose if you know it, and the dates. That changes my plan more than anything else.
Placement and dose shape the result far more than the label. A well-placed Korean toxin and a well-placed original brand look the same in the mirror; a poorly placed dose looks wrong whichever brand it is. Our guide to masseter botox gone wrong shows how much of a poor outcome comes down to technique rather than product.
The same brand choice applies to medical uses such as hyperhidrosis treatment in South Korea. Skin botox is different again: it is a diluted toxin spread through the skin rather than into a muscle, and Korean skin botox before and after explains what that changes.
What patients ask me next
"Can I switch brands between sessions?"
Generally, yes β many patients do. Tell me what you had last time and how long it lasted, and I will plan the dose for the new product rather than copy the old number.
"Will I be able to tell the difference?"
In most cases, no β when the dose is right for each product, the result looks the same. Our botox before and after guide and crow's feet before and after show what an honest result looks like.
"Why do Korean clinics use so much Korean toxin?"
Several toxins are made and approved here, and they are widely used. Our guide to botox from Korea covers the wider picture.
The honest limits
No brand makes botox last indefinitely, and none of them fills hollows or lifts loose skin. Any of these products can be the right one, and any can disappoint if the dose or placement is wrong. Toxin is not suitable during pregnancy or breastfeeding, or for people with neuromuscular disorders. What I can promise is that the product is named on your estimate, the reason for choosing it is explained, and the dose is planned for your muscle β not for a price list.
Book a consultation
If you are unsure which toxin suits you, send us what you have had before and when, and I will recommend a product with the reasons. We will arrange a consultation in Gangnam, or a photo consultation first if you are still abroad. An English interpreter joins every visit, and you receive an itemised written estimate before anything begins β international and local patients pay exactly the same.
FAQ
Frequently asked questions
Q1Is Korean botox the same as American botox?
They work the same way: all are botulinum toxin type A and temporarily relax the targeted muscle. What differs is the manufacturer, the formulation, the length of the clinical record and the price positioning.Q2Which botox brands does HERA use?
HERA uses Allergan Botox (the original brand), Xeomin from Merz in Germany, and two Korean toxins: Coretox from Medytox and Newlux from Newmeco, a Medytox affiliate.Q3Does Korean botox last as long as Allergan Botox?
At HERA all four products are used with the same expected timeline: effect within 3~7 days, full result around two weeks, and generally about 3~4 months of duration. Results vary from person to person and with dose and area.Q4What does complexing-protein-free mean?
It means the accessory proteins around the active toxin are removed during manufacturing, as with Xeomin and Coretox. This is associated with a lower theoretical risk of antibody resistance over repeated treatments.Q5Why is Korean botox usually less expensive?
Korean toxins are made domestically and some, such as Newlux, are positioned as value options; that reflects positioning, not a weaker mechanism. At HERA the product is listed on your itemised written estimate.
