How do botulinum toxin injections work?

Repeated muscle contractions are one of the causes of wrinkles in the face. Botulinum toxins like Botox temporarily block nerve signals to muscles. As a result, injected muscles can’t contract (tense).

They become weak or paralyzed. These effects can last for several months. The muscle injected is dependent on the area(s) of concern that you have. Several areas can be treated in one session.
