What is a botox unit?
Botox is measured in units. A number of units are needed to treat an area. Each areas needs differ to be effectively treated. The area right between your eyebrows will likely need 12 to 15 units. To treat the entire central forehead requires about 18 to 22 units. The “crow feet” (outside of the eyes) require around 6 units per side. A full treatment of the central forehead and crow feet requires about 32 units total.
