Comparison

Botulax vs Botox

Botulax is a Korean botulinum toxin sold in the US under the name Letybo. How it compares with Botox on units, duration, cost and where you can get it.

At a Glance

Botulax is a botulinum toxin made in South Korea, where it is the best-selling brand. The same toxin is sold in the United States under a different name, Letybo, so a vial labelled Botulax is not the version approved for use here. Botox is the original brand and the one most American clinics stock. No trial has compared the two directly, and the honest summary is that they are close relatives with different labels.

Also called Hugel, letibotulinumtoxinA, Letybo

Also called Botox Cosmetic, onabotulinumtoxinA

What it is

A botulinum toxin type A from Korea

Made by Hugel. It has been the leading toxin brand in South Korea for years and is exported widely.

The longest-established botulinum toxin

The version most of the published research used, and the one most US clinics keep on the shelf.

The name question

Sold as Letybo in the United States

Same maker, same active ingredient, different brand name for the American market. A vial labelled Botulax is meant for other countries.

One name in every market

Botox is Botox wherever you have it, which removes this particular confusion.

What it is used for

Lines that appear when you move

Frown lines between the brows, forehead lines, crow's feet.

Lines that appear when you move

Approved in the US for specific movement lines; other areas are treated off-label.

Both
Neither one softens a line that sits there when your face is completely still. That is skin damage or lost volume, and it needs a different treatment.

How long until it works

Two to four days to start

Full effect at about two weeks, as with the others.

Three to four days to start

Judge the result at two weeks, not on day three.

How long it lasts

About three to four months

The reported range is the same. Nothing has been published showing it outlasts Botox.

About three to four months

Movement returns before the line does.

Are the units the same

No

Its units are its own. A dose written for one brand cannot be copied across to another.

No

Same point in reverse. The injector has to know which product is in the syringe.

The downside

Vials sold online cannot be traced

Nobody can confirm how a vial bought online was stored, or that the contents match the label. Counterfeits of popular Korean brands are a known problem.

The usual toxin trade-offs

Bruising and headache for a few days are common. If the toxin spreads slightly past the target, a brow or eyelid can droop for weeks until it wears off.

Cost

Cheaper per vial outside the US

Price is the reason most people ask about it in the first place.

Priced per unit or per area

Ask which way your clinic charges before you agree to treatment.

The at-home or drugstore version

There is none

It is an injected prescription drug, and there is no topical form of it.

Peptide serums borrow the name

"Botox in a bottle" creams sit on the surface of the skin. The muscle is several millimetres down, and a cream cannot reach it.

Who each suits

Best for
Someone treated in a country where Botulax is approved and supplied through a clinic.
The mindset
A different label on a close relative, not a different class of treatment.
Best for
Anyone who wants the brand with the longest record and the widest availability.
The mindset
Predictable, well documented, and easy to compare between clinics.

Same toxin, two labels

Botulax and Letybo are the same product sold under different names: One name is for the Korean and export markets, the other for the United States.

That answers the question most people arrive with: If you liked Botulax abroad, the American equivalent exists and it is called Letybo.

It also explains why a Botulax vial in a US clinic is a red flag: The approved route into the country carries the other name on the box.

Why brand still matters with botulinum toxin

Every brand of botulinum toxin has its own unit strength: The number on one vial does not mean the same amount of effect as the same number on another.

That is a dosing issue, not a marketing one: An injector working from a dose they learned on one product has to convert before using a different one, and getting it wrong shows up as too much or too little movement.

So the useful question at the appointment is which product, and how many units of that product: A price quoted per area hides both.

What buying a toxin online means in practice

A vial bought online has no path anyone can check: Botulinum toxin is a prescription drug, and the chain from factory to website to doorstep leaves no record you can verify.

Two things become unknowable: what is in the vial, and how it was kept: Toxin has to stay cold to work. Fake versions of the popular Korean brands also circulate.

Injecting it is a medical act regardless of where the vial came from: The dose, the depth and the exact muscle decide whether the result looks natural.

Has anyone compared them directly

No published trial has put Botulax against Botox: Claims that one lasts longer, spreads less or looks more natural come from clinic experience rather than from a head-to-head study.

Before you book

Ask which product is being used, and ask to see the vial and the box.

Ask how many units of that product you are having, not just the price of the area.

Book a review at two weeks, when the result has settled and a small top-up can be added.

Tell your injector about any toxin you have had before, including treatment abroad.

Questions people ask

+
Is Botulax the same as Botox?
No. Both are botulinum toxin type A, but they come from different makers and have their own unit strengths. Botulax is made in South Korea by Hugel.
Is Botulax available in the US?
Not under that name. The same toxin from the same maker is sold in the United States as Letybo, so a vial labelled Botulax is not the version approved for use here.
Does Botulax last as long as Botox?
The reported duration is the same, about three to four months. No trial has compared them directly, so any claim that one lasts longer is not backed by a study.
Are Botulax units the same as Botox units?
No. Each brand has its own unit strength, so a dose written for one cannot simply be copied across to the other. The injector has to know which product is in the syringe.
Why is Botulax cheaper?
It is priced for markets outside the United States, and vials bought online skip the licensed supply chain. That is where most of the price gap comes from.
How can I tell if a Botulax vial is genuine?
If it was bought online, you generally cannot. Counterfeit versions of the popular Korean brands circulate, and there is no way to confirm how a vial was stored on its way to you.
