Neurotoxin has many cosmetic uses and a very long safety record, with several millions treatment done worldwide. Experience has shown that it can be applied to different areas of the face safely, with profound effects. The key to safety and efficacy is knowledge of how the toxin works, precise placement and detailed understanding of the anatomy of the face.

Neurotoxin is used to target specific muscles, relaxing the muscle that is responsible for particular frown lines, for example the corrugators for the glabella frown line and masseter for the square jaw.
