If you’re thinking about getting Botox for the first time, one of the biggest questions you probably have is how many units of Botox you really need.
Every face is different, and every area requires a different amount based on muscle strength, wrinkle depth, and your aesthetic goals.
And here’s the truth, there’s no “one-size-fits-all” number. But there are common dosage ranges that give natural, smooth, and long-lasting results.
In this simple, detailed guide, you’ll learn exactly how many units most people need for the forehead, crow’s feet, frown lines, brow lift, lip flip, jawline slimming, and more.
You’ll also learn what factors change your dosage and how to avoid paying for more units than you need.
Let’s break it all down so you can walk into your appointment confident, informed, and ready for great results.
How Many Units of Botox You Need
Most clients need 8 to 60 units of Botox, depending on the treatment area. Smaller areas like the lip flip or bunny lines need around 2–10 units, while stronger muscles like the masseters can need 25–50 units per side.
Below is a detailed chart that breaks everything down.
Botox Units Chart for Each Area
| Treatment Area | Average Units Needed |
| Forehead Lines | 8–20 units |
| Frown Lines (11s) | 10–25 units |
| Crow’s Feet | 6–20 units per side |
| Brow Lift | 2–5 units per side |
| Bunny Lines | 4–10 units |
| Lip Flip | 4–8 units |
| Gummy Smile | 2–6 units |
| Masseter / Jaw Slimming | 25–50 units per side |
| Chin (Orange Peel Texture) | 6–10 units |
| Neck Bands (Nefertiti Lift) | 25–60 units |
| Under-Eye Micro Botox | 2–6 units per side |
Your injector will personalize these numbers based on muscle strength, goals, and facial anatomy.
Now let’s go deeper into each area so you understand what affects dosage and how your injector decides.
Forehead Botox Units (8–20 Units)
Most people need 8 to 20 units in the forehead.
Why the range?
Because forehead muscles vary a lot. Someone with light lines may only need 8–10 units. Someone with stronger movement may need 16–20.
Your injector will also consider your brow position. Using too many units can drop the brows. That’s why forehead Botox must balance with your frown line area (the 11s).
If you treat your forehead, you almost always need Botox in the 11s too to keep everything balanced.
Frown Lines (11s) Units (10–25 Units)
The glabellar complex—your “11s”—usually needs 10–25 units.
These muscles are strong, so they often need the most product for smooth results.
Clients who make expressive frowns often need on the higher end. If you want a very soft look instead of frozen, your injector can use a lighter dose.

Crow’s Feet Units (6–20 Units Per Side)
Crow’s feet depend on how you smile.
Some clients only need 6–8 units, while others with deeper lines need 12–20 units per side.
Botox smooths the outer corner while keeping your smile natural. You never lose expression with a balanced dose.
Brow Lift Botox Units (2–5 Units Per Side)
A small amount of Botox—around 2 to 5 units per side—helps lift the brows slightly.
This treatment pairs well with forehead or frown line Botox to open the eyes and give a fresh look.
This is often called a “chemical brow lift” and gives a subtle, natural lift.
Bunny Lines Units (4–10 Units)
Those little wrinkles on the nose when you smile or laugh usually need 4–10 units.
A small dose smooths the area without changing your smile.
Lip Flip Units (4–8 Units)
A lip flip requires 4–8 units.
This is a tiny dose used to relax the top lip so it flips outward slightly, giving a fuller look without adding volume.
If you want actual volume or shape, consider lip injections, which you can read about in our guide on lip filler aftercare.
Gummy Smile Units (2–6 Units)
A gummy smile correction needs 2–6 units to relax the muscle that pulls the upper lip too high.
The result is a more balanced smile that still looks natural.
Masseter/Jawline Slimming Units (25–50 Units Per Side)
Jawline slimming or teeth grinding treatment uses 25–50 units per side.
This is one of the highest-dose areas because the masseter is a strong muscle.
Clients who grind their teeth often need more units, especially during their first treatment.
This treatment is also popular for facial balancing, which you can explore through our non-surgical treatments like the non-surgical nose job or dermal fillers.
Chin Botox Units (6–10 Units)
If the chin has dimpling or an “orange peel” texture, 6–10 units smooth the area.
Botox relaxes the mentalis muscle and helps the chin look softer and more balanced.
Neck Bands (Nefertiti Lift) Units (25–60 Units)
A neck lift with Botox needs 25–60 units, depending on how strong the platysmal bands are.
This treatment softens vertical lines and improves jawline definition.
For even stronger tightening, clients often pair this with non-surgical skin tightening.
Under-Eye Botox Units (2–6 Units Per Side)
Under-eye micro Botox uses very low doses—around 2–6 units per side.
This smooths fine lines without affecting blinking strength.
If you have hollow under-eyes instead, Botox won’t help, you may need fillers. See our full guide on under eye fillers.
What Affects How Many Units of Botox You Need
Botox dosage isn’t random. Injectors look at several things before deciding:
1. Muscle Strength
Stronger muscles need more units.
People who frown or raise their brows often need higher doses.
2. Wrinkle Depth
Deep lines need more product and sometimes require filler with Botox.
3. Facial Anatomy
Everyone’s muscles are shaped differently. A standard “forehead dose” doesn’t work for every face.
4. Age
In your 20s and 30s, you may need fewer units for prevention.
In your 40s–60s, lines may need slightly higher doses.
You can read more in Preventative Botox Treatments.
5. Treatment Goals
Some clients want a soft, natural look with more movement.
Others want smooth, long-lasting results and choose a higher dose.
6. How Long You Want It to Last
More units = longer lasting results.
Lighter doses wear off faster.
How to Avoid Overpaying for Botox Units
Botox should never feel confusing or overwhelming.
Here’s how to protect yourself:
Choose an experienced injector
Botox must be placed with accuracy. Poor technique leads to wasted units.
Avoid “cheap per-unit pricing” traps
Cheap Botox is usually diluted or low quality.
Ask for a personalized treatment plan
A good injector explains why you need a certain number of units.

How Long Do Botox Results Last?
Most clients see results last 3–4 months, sometimes longer for areas like the masseters.
Using consistent treatment cycles helps your muscles stay relaxed, which often reduces future dosage needs.
