They Are Diluting Your Botox.
And you deserve to know what that really means.
Let’s start with the uncomfortable part.
Yes — your Botox is diluted.
And before you panic… keep reading.
Because this is exactly where patients get confused — and where misinformation spreads.
I’m a board-certified dermatologist, and I want you to understand what’s actually happening when that syringe touches your skin.
Patients love to ask:
“Do you dilute your Botox?”
It sounds like the right question.
It’s not.
That question doesn’t tell you whether you’re being treated appropriately. It doesn’t tell you if you’re getting what you paid for. And it doesn’t protect you.
Here’s why.
Botox — specifically Botox — does not come in liquid form.
It arrives as a dry powder in a vial.
Before it can be injected, it has to be mixed with sterile saline. That process is called reconstitution.
So technically?
Every single Botox treatment involves dilution.
Always.
The concentration can vary slightly between providers — and that alone does not determine whether your treatment is good or bad.
I personally adjust dilution depending on:
The area being treated
The amount of spread I want
Whether I need precision vs diffusion
More concentrated isn’t automatically better.
More dilute isn’t automatically worse.
Which brings us to what actually matters.
Here’s the only question that truly matters:
Are you receiving the number of units you are paying for?
That’s it.
Botox is sold and priced per unit.
If you are paying for 40 units, you should receive 40 units.
If you are paying for 20 units, you should receive 20 units.
The dilution ratio does not change the number of units in the vial.
What changes your result is whether:
The injector actually draws the full number of units
You are told how many units you’re receiving
The documentation matches what you’re paying for
If someone uses fewer units than appropriate for the area — even if properly diluted — your results will be weaker and shorter-lasting.
Instead of asking about dilution, ask:
1️⃣ “How many total units are we using today?”
Not “areas.”
Not “syringes.”
Units.
The answer should be immediate and specific.
2️⃣ “How many units are you drawing up right now?”
You won’t be holding the syringe — but you can absolutely ask, in real time, how many units are being prepared for you.
For example:
“How many units are we putting into the forehead today?”
“How many units total are we using?”
That is a completely reasonable question.
You are paying for a medical product that is dosed and billed in units. Clarity around that number should never feel uncomfortable.
If the answer is vague, deflected, or brushed off, that’s more concerning than any dilution ratio.
3️⃣ “How does today’s dose compare to my last visit?”
A reputable injector tracks your dosing history. Adjustments should be intentional and explained.
You don’t need to memorize this like a board exam, but rough ranges help you spot inconsistencies:
Glabella (the 11s): 10–25 units
Forehead: 10–20 units
Crow’s feet: 4–9 units per side
If someone advertises a “Full Face Botox Special” at a bargain price and uses 18 total units… that’s not efficiency. That’s under-treatment.
Most patients should see results for 3–6 months.
If it’s fading at 4–6 weeks, barely softening lines, or requiring frequent touch-ups, the first suspicion should be:
Were enough units used?
✔ Botox has to be diluted. Stop asking about the dilution.
✔ Units are the issue.
✔ You should know exactly how many units you’re paying for.
✔ You should receive exactly that many units.
✔ Your results should last around 3–6 months.
Above all, you need to know that you can trust your injector. In cosmetics, clarity equals trust.
And the most important number in the room isn’t the dilution ratio.
It’s the unit count.
