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. 

Average dose for the forehead is between 5 to 10 Units of Botox depending on the patient. More in younger, less in older patients. I usually recommend to treat the eyebrow too to get a brow lift and that usually takes between 20 to 25 Units. The effect usually last between 3-4 months in most people. 1 month is very fast for the Botox to wear off. I would see my injector and discuss this with him. Good luck.

Typically dosing is 16-24 units for the glabella and 6-10 units for the frontalis. The doses required  maybe higher based on gender (men typically require higher doses then females) and muscle strength. Botox should last somewhere between 3-4 months in the majority of patients.
