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

45 units of Botox is a little more than twice the average "single" dose for a given site. Forehead muscles are strong and often require extra amount. As to how many injections it takes to deliver 45 units...or any number of units depends entirely on the operator's preferred technique. Whether he/she likes to deliver smaller or larger amounts per injection site.

You may want to discuss your concerns with your plastic surgeon.  Each injector has their own technique when injecting Botox.  If you are happy with your results then it may be that this new technique may be just fine for you.  The number of injections does not necessarily correlate with the amount of product injected.
