Botox Cost — Forehead Lines
Answer first: Forehead Botox typically uses 10–20 units — about $130–$260 at $13 per unit. Most visits also include the glabellar frown lines (20 units, FDA-approved), bringing the typical combined total to 30–40 units, or roughly $390–$520.

Why the forehead and frown lines are usually treated together
Answer first: The forehead muscle lifts the brow, while the glabellar muscles pull it down. Softening the forehead alone, without the glabella, can leave the downward pull unopposed — which is why providers commonly treat both together: 10–20 units for the forehead plus the FDA-approved 20 units for the glabella, for a combined visit of roughly 30–40 units ($390–$520 at $13 per unit).
Forehead dosing also depends on forehead height and muscle strength, so two people can legitimately receive different unit counts for the same area. The range on this page is a budgeting guide, not a prescription.
Frequently asked questions
How much does forehead Botox cost on its own?
Forehead-only treatment at 10–20 units and $13 per unit is about $130–$260. With the usual glabella combination (30–40 units total) it is about $390–$520.
Can I treat just my forehead lines?
Some providers will, some will recommend adding the glabella for brow balance. That is a clinical judgment made after assessing your brow position and muscle activity — ask the provider to explain their reasoning and unit count.
