How much does Botox cost?That depends on many factors: areas of the face treated, number of units applied, and depth of the wrinkles. Some plastic surgeons and dermatologists will charge by the number of units applied, while others will charge a specific amount for a given anatomic area. In general, a plastic surgeon or dermatologist will charge anywhere from $6 to $14 per unit of Botox. This includes the application fee, but it does not necessarily include “touch-ups”. Treatment of forehead wrinkles, crow’s feet, and frown lines in one session will require about 60 units. Men usually require more units to treat the same area.
