Why “40 units vs 60” is the wrong way to compare quotes for neurotoxin treatment
You have two quotes for the same concern. Clinic A says 40 units. Clinic B says 60. It can feel like you are paying for less, or being “sold” more, based on one number.
Units are a real dosing measurement, but they are also product specific. The BOTOX Product Monograph for onabotulinumtoxinA states that dosing is based on a product specific activity measurement, and that units are not interchangeable with other botulinum toxin products.
For you, the practical takeaway is simple: “How many units?” is a weak comparison tool. The better comparison is the plan, which includes what areas are being treated, how dosing decisions are made for your muscle strength and facial balance goals, and what the follow up plan looks like.
What “Units” actually mean in botulinum toxin treatment
In everyday life, a unit often sounds like a universal measurement. In botulinum toxin treatment, it is more specific than that. The Canadian product monograph for BOTOX (onabotulinumtoxinA) explains that dosing is based on a product specific activity measurement, and it states that units are not interchangeable with other botulinum toxin products.
This is why a simple units total, especially when it comes from two different clinics that may not even be using the same botulinum toxin product, can mislead you. A higher number does not automatically mean “stronger,” and a lower number does not automatically mean “more conservative.” The unit number only becomes meaningful when you know what product is being used and how the injector is planning your treatment for your face.
If your goal is a refined result that still looks like you, units matter, but context matters more. Aesthetic Nurse Marta typically frames dosing decisions inside a full face conversation, because facial balance goals and safety margins are part of responsible planning.
Why “40 vs 60” is a poor comparison for your face
People compare units because it is the only number they can see. It feels objective, like comparing millilitres or grams. The monograph language above is the key reason that comparison breaks down.
A second reason is practical: treatment planning is not only a total. It is a map. The number of areas treated, how those areas are chosen, and the dosing strategy for each area all change what the final total looks like.
When you are deciding between two quotes, the smarter move is to compare the thinking, not the arithmetic. If you are looking for facial wrinkles treatment, you can start by reading how we approach assessment for Full face Botox so you have a clearer baseline for what a plan can include.
A calm checklist: better questions than “How many units?”
These are the questions that usually tell you whether a quote is built around your goals and a careful dosing approach, rather than around a single number.
- What areas are you treating for this plan? Ask the injector to name the areas included, so you understand what the quote actually covers.
- Which botulinum toxin product are you using? Units are product specific, so the product name matters for interpreting the number.
- How do you decide dosing for my muscle strength and facial balance goals? Your plan should be explained in a way that connects your facial movement patterns with what you are trying to improve.
- What is your follow up plan? Ask what the clinic does after treatment, and how they handle adjustments or concerns.
- What should I review for preparation and aftercare? Good planning includes what you do around the appointment, not only what happens during it. Our Patient information and care page can help you prepare questions before you come in.
A non obvious point that often saves people from confusion is this: a units total can look “higher” simply because it includes more areas, or because the plan is different. If you compare totals while the plans are not matched, you are comparing two different treatments.
If you are choosing an injector in Vaughan or elsewhere in the GTA, it also helps to understand who will be assessing you and delivering the treatment. The accountability and clinical approach should be clear. You can review Marta’s background on the About Marta Morozova page.
If you are collecting quotes, keep the units number in perspective. The BOTOX Product Monograph for onabotulinumtoxinA is explicit that dosing is based on a product specific activity measurement and that units are not interchangeable with other botulinum toxin products.
Frequently Asked Questions
Are Botox units the same across different products?
No. The BOTOX Product Monograph for onabotulinumtoxinA states that dosing is based on a product specific activity measurement and that units are not interchangeable with other botulinum toxin products.
Does a higher unit count mean a stronger treatment?
Not automatically. A total can look higher simply because it covers more areas or follows a different plan. The number only becomes meaningful when you know which product is being used and how the injector is planning your treatment.
How should I compare two quotes?
Compare the thinking, not the arithmetic: which areas are treated, which product is used, how dosing is decided for your muscle strength and facial balance goals, and what the follow up plan looks like.
What are better questions than how many units?
Which areas the plan includes, which botulinum toxin product is used, how dosing is decided for your face, what happens after treatment if adjustments are needed, and what to review for preparation and aftercare.
If you want a plan that matches your facial movement and your goals, the next step is a consult. You can request one here: consultation request.
