How Many Units of Botox for the Forehead?
Published by Renownly · Prices from Google AI Overview answers captured November 2026
The FDA label for Botox Cosmetic recommends 20 units for forehead lines, given together with 20 units for frown lines, for 40 units in total. Published expert ranges for the forehead alone run from about 8 to 25 units. Your injector decides your dose.
The doses, and what they cost
| Source | Forehead units | Cost at $10 to $15 a unit |
|---|---|---|
| FDA label, forehead with frown lines | 20, plus 20 for frown lines (40 total) | $400 to $600 |
| FDA label, adding crow’s feet | 20, plus 20 and 24 (64 total) | $640 to $960 |
| 2016 global consensus | 8 to 25 | $80 to $375 |
Cost is an estimate for the product at the typical Dallas–Fort Worth rate. The consensus row covers the forehead only, so any frown line treatment would add to it. To add other areas, use the Botox cost calculator, or see what one unit costs by city.
How the label places the 20 units
The Botox Cosmetic prescribing information lists 4 units into each of 5 sites in the frontalis, the muscle that raises your eyebrows. The other 20 units go into 5 sites between the brows.
The label tells the injector to assess the size of the forehead and how the muscle moves before locating those sites, and to keep the lower row of injections at least 2 cm above the eyebrow.
Why your number may differ from 20
The label gives one recommended dose. Experts writing consensus papers describe a range, because foreheads and muscle activity vary. The 2016 global consensus lists 8 to 25 units, as tabulated in a 2023 review of consensus doses. These ranges describe what experts report using. They aren’t a recommendation for you, and doses outside the label are your injector’s call.
What the label says about side effects here
In the label’s forehead line trials, the most common adverse reactions were headache (9%) and brow ptosis (2%). The label also carries a boxed warning about the toxin spreading from the injection site. Read it with your provider before treatment.

The 40-unit label dose comes to about $400 to $600 at the typical Dallas–Fort Worth rate of $10 to $15 per unit. Twenty units alone would be about $200 to $300.
Do men need more Botox units in the forehead?
