Quotes for Dysport that list a bigger unit count than quotes for Botox look pricier until you learn what a unit measures. Folsom shoppers comparing the two should settle that before comparing totals.
A unit is not a shared measure
Cleveland Clinic says a defined unit of Botox and Dysport is not equal, and that in general one unit of Botox equals three units of Dysport.
It adds that the difference comes down to how each manufacturer puts together their product, and that Dysport usually requires a higher number of units to achieve a similar effect.
Where the lower unit price comes in
Cleveland Clinic also says that because Dysport costs less per unit than Botox, the bill for either treatment is similar.
So the unit count tells you about the product, and the bill tells you about the cost. Counting units across the two brands tells you little until the price per unit is beside it.
Two numbers to ask for
Ask for the unit count and the per-unit price side by side, then multiply them yourself. Also ask how soon you would need to return, so the follow-up is priced into the comparison.
Cleveland Clinic has a page on Botox Cosmetic uses and side effects and another on cosmetic injectables.
