Need More Botox In Forehead After 6 Weeks, Shouldn't It Last Longer?

Much information has been provided by panel members. 

Quite simply, you should be receiving a longer duration of effects with 20 units of Botox to your forehead.  There may be a several factors involved that are contributing to this problem:  improper dilution, dosing, placement or possibly a developing resistance. Ideally, you should be holding onto duration/benefits longer as you become more consistent with treatments.

It is not recommended to get frequent dosing in less than 3 months.  Your concerns should be addressed by the one doing the treatments to determine a way to obtain a better duration.

The FDA approved Botox for a duration of three months.  Granted this is just an average as results will vary for each patient.  Some people will see the effects last longer than 3 months and others will experience shorter than 3 months.  It may be an issue that you did you receive enough units of Botox in the desired area, which in this case is your forehead.  At Contour Dermatology we typically require 20 to 50 units for the forehead.  I also have all of my patients come back for a two-week, follow-up appointment to make sure they are satisfied and to determine whether the Botox we gave them was an effective dose.
