Botox price for forehead wrinkles?

If you are new to Botox I would recommend 10 units for the forehead. Pricing for Botox varies depending on location and expertise of the injector.  The price ranges from $10-18 dollars a unit.  To answer your question it would be $100 to inject Botox in the forehead if you are getting 10 units. RegardsAnil Shah

Price is one factor. But of course it is not the most important factor. Ultimately you want this medical procedure done by an experienced expert that can do this safely and with the best results. 
Having said this, at our practice, cost for this wrinkle injection is $12.50/unit. Or $5/unit for the European version. This works out to be approx $125 -$250 for forehead area as an example. If you use a larger amount of wrinkle injections, the cost goes down to $8.79/unit. 
I hope this is of help.

Botox pricing will depend on the injector, geographic market, and the particular patient. Some injectors price Botox by the area while others price it by the unit.
If your Botox is being priced by the unit, then it comes down to how many units you will require to achieve the result you are looking for. Most patients will require 10-20 units to treat the horizontal forehead wrinkles, with an additional 20 or so units required to treat the wrinkles between the eyebrows in the glabella area.
Also, $10/unit is quite low in most markets, so be sure that you are seeing a skilled physician injector.
All the best,
