How Does Botox Work?
Botox is a form of botulinum toxin type A — a substance that binds to the muscle receptor and prevents contraction. When the muscle doesn’t contract, the wrinkle doesn’t form. In addition, the ones that already exist gradually disappear.
Although Botox prevents muscle contraction, don’t worry; you will still be able to make facial expressions. You just need to choose an experienced specialist. This will keep you from being over-injected.
