In short
- Separate the brand from its ingredient name. [1][2]
- Do not compare units across brands yourself. [1][2]
- Ask to see the label and check Thai FDA authorization. [4]
Separating everyday names from brands
When someone uses a shorthand name, ask: “What is the full product name on the box?” This helps patients and clinic staff discuss the same product.
The U.S. label uses BOTOX as the brand name and onabotulinumtoxinA as the ingredient name. [1] Keep the everyday term separate from these names when reading the label.
Reading the ingredient name
Botulinum toxin is the broader category; onabotulinumtoxinA and incobotulinumtoxinA are ingredient names listed on labels for different brands. [1][2]
These medicines reduce muscle contraction, and the U.S. FDA has approved certain products for temporary improvement in the appearance of particular facial lines. [3] Ask your doctor which product and indication fit the concern you want assessed.
Full names and units
| Product name in the shop | Ingredient in prescribing information |
|---|---|
| Botox 100 Units | onabotulinumtoxinA [1] |
| Xeomin 100 Units | incobotulinumtoxinA [2] |

These examples pair product names in the shop with ingredient names in U.S. prescribing information. Also ask to see the documentation for the specific version your clinic intends to use.
- Units measure potency using a product-specific preparation and test method. Both labels state that units cannot be compared with or converted into those of other products. [1][2]
- Use the full name to identify the product. Your doctor decides the amount and treatment plan after assessment; the number on a box is not an injection plan.
How filler differs
Dermal fillers are gel-like materials used to add fullness to tissue. The medicines discussed above act on muscle contraction, so they belong to a different product category. [3]
Start the consultation with the concern you want assessed, such as the location of a line, instead of choosing a procedure based on a familiar name.
Questions for your consultation
These injectable products must be used by a licensed doctor in a licensed clinic. [4]
- Ask for the full product name and check Thai FDA authorization, as the agency advises. [4]
- For clinic purchasing, check the actual product label for the manufacturer, country of manufacture, pack size, form, expiry date and storage requirements.
- Ask why the doctor chose the product, what precautions apply and whom to contact after treatment.
- Share your health history and current medicines so your doctor can assess you before a decision.
FAQ
What is โบท็อก?
Here, the Thai term refers to botulinum toxin medicines, which reduce muscle contraction. [3] To identify the medicine being used, ask for its brand and ingredient name on the label.
What is it used for?
The U.S. FDA has approved certain medicines in this category for temporary improvement in the appearance of particular facial lines. [3] Your doctor should check the intended product’s indications and assess whether it is appropriate for you.
How many days after an injection will I see a change?
Prescribing information for the Botox brand’s cosmetic formulation describes muscle effects beginning within one to two days and increasing during the first week. [5] This describes the onset of action, rather than guaranteeing when everyone will see a change; ask your doctor when to assess your response.
Which brand should I choose?
Let your doctor choose after assessment, and compare label details such as manufacturer, country, pack size, form and storage requirements rather than deciding by country alone. Units cannot be compared with or converted into those of another product. [1][2]
How does it differ from filler?
Botulinum toxin medicines reduce muscle contraction; fillers are gel-like substances used to add fullness to tissue. [3] Your doctor should assess the concern before choosing a procedure.
This information is general knowledge and does not replace a doctor's advice. Every procedure should be done by a licensed doctor.
