Botox
Botox is the brand name for Botulinum Toxin (BT) which is produced by the bacterium, Clostridium Botulinum.[1] It has been used to correct facial creases and wrinkles.
How does Botox Work?
1. Normally, brain transmits messages through nerves (by a substance called Acetylcholine) to the muscles thereby allowing them to contract and move.
2. BT blocks the release of acetylcholine which prevents contraction in the injected muscle, thereby causing the wrinkle to relax and soften.
