Can you have botox injected anywhere other than the face? Like the buttocks?

Botox can be injected into any muscle technically.... would not recommmend anywhere in the buttock region as could really affect the way you walk, cause hip/back issues. Also due to the size of the muscles there it would take a lot of Botox (think thousands not hundreds of dollars). Also would recommend cool sculpting as it is fda cleared for that area - also known as “banana roll” to some people.

Thank you for your question.
Botox would not help in the buttock area to reduce fat.  Botox works by preventing muscle contraction and helps smooth wrinkles in mostly the head and neck regions.  
Kybella is an injection that can reduce fat but is indicated for under chin fullness.  There are off label uses for the product but treating any significant area with Kybella would not be cost effective. Liposuction or any of the non invasive body contouring devices such as Vanquish or Coolsculpting might be an option.  Seek a board certified plastic surgeon for an in person exam to discuss your goals.
