How does Botox work?

Repeated muscle contractions from frowning, squinting, and other facial expressions cause your skin to furrow and fold, gradually resulting in the formation of facial lines and wrinkles in your upper face.

In addition, as you age some muscles can become stronger than others causing a downward pull on your skin effecting your mouth, jowls, chin and neck.  

Botox temporarily reduces the underlying muscle activity that causes these problems, to restore your facial features and help your skin look visibly smoother.
