The problem lies in the fact that the coloquial definition of "unit" is conflated with volume of product. Hard to see how this can be overcome other than by patient and repetitive explanation by the sales team to the treatment providers and in turn, the providers to the customers.
The problem is comparing units of Daxxify to units of Botox regardless of the context. Doing that will inevitably lead to confusion and disinformation, benefiting RVNC's competitors.
