How many units of Botox in the forehead is effective?

The typical standard Botox Cosmetic doses for the glabella (in between the eyes) is 20 units and the forehead (frontalis muscle) is about 10 units on average.  These doses can go up or down based on how strong the muscles are and how much movement you want.  I would go back to your treating doctor to explain what is going on and see if he/she can add more or "touch-up" the area to make you happy.

The amount of Botox needed to treat the forehead can vary from patient to patient, but I would say an average amount would be about 20-25 units.  Since you received 30 units, I would say this should be an adequate dose for most people.  If you feel your wrinkles are coming back a month after your treatment, I would contact the physician who treated you so that you can be evaluated.  It may be possible to have a touch up treatment to help.  

Thank you for your question. The number of units needed can vary from patient to patient. The typical amount needed to treat the glabella is 20 units and for the forehead is 10 units. I would say you received the correct dosage. I would contact your treating physician if you feel your wrinkles are coming back a month after treatment. It may be possible to have a touch treatment.
