Why units matter more than “how much Botox”
Botox is priced and dosed by the unit, not by the vial or the area. A unit is a measure of biological activity, not volume – so “how much Botox” is really always a question about how many units a specific muscle needs to relax the way you want it to.
This is also why Botox at KORA is priced per unit, at $13.50 – the cost of your treatment is a direct function of how many units your specific muscles need, not a flat fee per area that is the same for everyone.
Typical units by area
| Area | Typical units |
|---|---|
| Forehead lines | 10 to 20 |
| Frown lines (glabella, the “11s”) | 15 to 25 |
| Crow’s feet (both sides) | 10 to 20 |
| Full upper face (forehead, frown lines, crow’s feet) | 40 to 60 |
| Masseter, jaw slimming (both sides) | 40 to 60 |
| Underarms, each side | 50 |
| Lip flip | 4 to 8 |
These are starting ranges, not a menu. The right number for you depends on your muscle strength, your goals, and how your face moves – not a fixed formula applied to everyone.
What actually decides how many units you need
- Muscle strength. Stronger muscles need more product to fully relax. This is the single biggest factor, and it is why the same area can need very different doses in two different people.
- Sex. On average, male facial muscles are stronger than female ones, which is why men often need noticeably more units in the same area to get a comparable result.
- Your goal. A soft, natural reduction in movement takes fewer units than a more complete freeze. Neither is right or wrong – it is a conversation about what you want, not a fixed target.
- First treatment versus repeat. Consistent treatment over time can mean the muscle needs less to achieve the same result, since it weakens gradually with repeated use.
- How many areas are treated together. Muscles around the eyes and forehead interact, so treating them as a set sometimes changes the units needed in each individual area.
What this means for cost
At $13.50 per unit, the units table above translates directly into a price range:
| Treatment | Units | Approximate cost |
|---|---|---|
| Frown lines only | 20 units | $270 |
| Full upper face | 50 units | $675 |
| Masseter, both sides | 50 units | $675 |
These are examples based on the typical ranges above, not a quote. See current pricing for exact rates, and a consultation is the only way to get a number specific to your muscles.
Is more units always better?
No. Past the point that fully addresses the muscle you are treating, additional units do not improve the result – they just increase the chance of a heavier, less natural look. The goal is the right dose for your specific anatomy and goals, not the highest one.
Underdosing is the more common complaint, not overdosing. A treatment that “doesn’t seem to be working” is more often too few units for that particular muscle than a sign Botox itself failed. This is worth raising with your injector directly rather than assuming the treatment does not work for you.
Questions people ask
How many units of Botox do I need for my forehead?
Typically 10 to 20 units, though muscle strength varies enough between people that this is a starting range, not a fixed number.
How many units are in a syringe of Botox?
A standard vial is typically reconstituted to either 50 or 100 units total, then drawn into syringes in the amount needed for your treatment – there is no single fixed “units per syringe” figure.
Do men need more units than women?
Often, yes. Male facial muscles are generally stronger, which typically means more units are needed for a comparable result.
Is 20 units of Botox a lot?
It depends entirely on the area. 20 units is a full treatment for frown lines but would be unusually low for a full upper face or masseter treatment.
Why did I need fewer units the second time?
Consistent treatment over time can weaken the treated muscle gradually, meaning less product is needed to achieve the same result on repeat visits.
What happens if too few units are used?
The muscle is only partially relaxed, so some movement and lines remain – this is the most common reason a treatment feels like it “didn’t work.”
