Botox is dosed in units, and the amount depends on the area and your muscle strength. Common starting ranges are frown lines ("11s") around 20 units, forehead 10 to 20 units, and crow’s feet about 12 units per side (roughly 24 total). A full upper-face treatment often lands between 40 and 64 units. Smaller refinements like a lip flip (4 to 6 units) or bunny lines (2 to 5 units) use very little, while jaw slimming of the masseter can take 40 to 60 units total. These are typical published ranges — your injector sets your exact dose from your anatomy and goals, not a fixed formula.
How Botox dosing works
Botox is measured in units, not syringes or "areas." One unit is a standardized amount of the product; a treatment is simply the total units placed across your target muscles. Stronger muscles need more units, which is why doses are given as ranges rather than single numbers.
Typical units by area
The ranges below reflect commonly published cosmetic dosing. They are a reference point for conversation with your injector — not a prescription.
| Area | Typical units | Notes |
|---|---|---|
| Frown lines (glabella / "11s") | 20 units | The FDA-approved standard cosmetic dose |
| Forehead lines (frontalis) | 10–20 units | Kept conservative to preserve a natural brow |
| Crow's feet (per side) | 12 units | About 24 units for both sides |
| Bunny lines (nose) | 2–5 units | A small refinement |
| Brow lift | 2–5 units per side | Subtle lift by relaxing depressor muscles |
| Lip flip | 4–6 units | Softens the upper-lip roll |
| Chin dimpling (mentalis) | 4–8 units | Smooths an "orange-peel" chin |
| Gummy smile | 2–4 units | Very precise placement |
| Masseter (jaw slimming / TMJ) | 20–30 units per side | Roughly 40–60 units total |
| Neck bands (platysma) | 25–50 units | Advanced; highly provider-dependent |
Why your dose may differ
Muscle strength, facial anatomy, your goals (a soft, still-mobile look versus maximum smoothing), and whether you have had Botox before all shift the number. Men frequently need more units than women in the same area because their facial muscles tend to be larger and stronger. First-timers sometimes start conservative, then add units at the two-week check.
Units and cost
Because Botox is usually priced per unit, your dose drives your price. BlushLocal cost-guide estimates put the typical per-unit price around $10 to $15, though this varies widely by region and clinic. See real ranges in our Botox cost guide, and if you are wondering whether a larger dose is excessive, read is 50 units of Botox too much?
How injectors decide your dose
Your provider watches how your muscles actually move — how hard you frown, how high your brows lift, how deep your squint lines run — and combines that with your goals (soft and still-mobile versus maximally smooth) and your history with Botox. Two people asking for the same "forehead treatment" can correctly receive very different unit counts.
First treatment vs maintenance
First-timers are sometimes started a little conservatively, with the option to add units at the two-week check. Over time, some people settle into a slightly lower maintenance dose as the muscles weaken, while others keep a steady number. Neither is wrong; it depends on your muscles and your goal.
A note on Dysport and Xeomin units
Units are brand-specific. A Dysport unit is more dilute than a Botox unit (roughly 2.5 to 3 Dysport units equal 1 Botox unit), while Xeomin units are broadly comparable to Botox. So never compare a quote from one brand to another by unit count alone — compare by area treated and the total price. Our Botox vs Dysport guide breaks the dosing math down further.
Quick answers
How many units for forehead and frown lines together?
Commonly around 30 to 40 units combined, depending on muscle strength.
Do men need more units?
Often yes, because facial muscles tend to be larger and stronger.
Is more units better?
No — the right dose is the fewest units that reach your goal.
