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.
Made by Hugel. It has been the leading toxin brand in South Korea for years and is exported widely.
The version most of the published research used, and the one most US clinics keep on the shelf.
Same maker, same active ingredient, different brand name for the American market. A vial labelled Botulax is meant for other countries.
Botox is Botox wherever you have it, which removes this particular confusion.
Frown lines between the brows, forehead lines, crow's feet.
Approved in the US for specific movement lines; other areas are treated off-label.
Full effect at about two weeks, as with the others.
Judge the result at two weeks, not on day three.
The reported range is the same. Nothing has been published showing it outlasts Botox.
Movement returns before the line does.
Its units are its own. A dose written for one brand cannot be copied across to another.
Same point in reverse. The injector has to know which product is in the syringe.
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.
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.
Price is the reason most people ask about it in the first place.
Ask which way your clinic charges before you agree to treatment.
It is an injected prescription drug, and there is no topical form of it.
"Botox in a bottle" creams sit on the surface of the skin. The muscle is several millimetres down, and a cream cannot reach it.
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.
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.
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.
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.
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.
