I Was Charged for 45 Units of Botox. I Wonder if I Was Cheated?

It's a shame that you neither trust your doctor, nor can ask them to discuss your concerns such that you have to reach out to the internet.  45 units are a lot of units for just the forehead unless the glabella (between the eyebrows) is also injected.  There have been several times after I completed a treatment session, that my patients have asked me if I treated a certain area when I showed them a mirror. There are some injections that are so painless that the patient doesn't remember. If you look and feel the skin you can probably see a little swelling, drop of dried blood, or redness or feel a hardness at the injection site. It may be that the doctor did inject those areas you felt weren't done.

Every person is different.  We all have facial muscles of different strength and activity, so there is no one 'set rule' for how many units a patient needs.  In my practice I would on average use 30 units for the vertical frown lines and 10-15 units for the horizontal forehead lines.  So if by 'forehead' you mean the horizontal forehead lines and the vertical frown lines, then the number seems to make sense.

It is very important that you can trust your Botox injector as only they know how much they have injected.  The number of injections is not an indication of the dose delivered as the concentration can be different depending on the dilution method the doctor uses.  If you have a similar effect to previous injections, then you likely received a similar dose.  

 

Good Luck.
