The Food And Drug Administration is very direct in saying that “units” are not interchangeable. What may be considered “20 units” per dose of one product has no bearing on what “20 units” is of another. Daxxify uses “40 units” as a dose to treat Frown Lines. Other conventional wrinkle relaxers offer positive results for “20 units.” This does not mean that a patient receives twice the amount of product or neurotoxin. In fact, the amount of core active neurotoxin found in one dose of Daxxify is comparable to what you will find in conventional alternative treatments.
