Botulinum toxin is a purified substance that’s derived from bacteria. Commonly known types of botulinum toxin type A injections include Botox® and Dysport®.
Injections of botulinum toxin blocks muscular nerve signals, which then weakens the muscle so it can’t contract. The end result is diminished unwanted facial wrinkles.
Botulinum toxin can be used to help smooth and treat:
- Crow’s feet
- Forehead furrows
- Frown lines
- Neck skin bands
