The number of units you will need depends heavily on the number of treatment areas, your goals, and specific anatomy. For example, the jaw BOTOX usually requires more units than the glabella. Treating medical problems such as migraines and hyperhidrosis also requires more units of BOTOX than most cosmetic treatments. Patients with deeper wrinkles will also need more units of BOTOX.
Conversely, some treatments may only take a few units of BOTOX. Younger patients may also require fewer overall units. This is best determined during a consultation with an injector at Seattle Plastic Surgery.
