Description
Botulinum toxin has a long history and is clinically used for muscle relaxation to smooth wrinkles, reduce bulky muscles, and tighten the skin.
There are many brands of botulinum toxin, generally differing in diffusion range and duration of effect.
Botulinum toxin is a protein neurotoxin extracted from Clostridium botulinum. It works by binding to receptors at the neuromuscular junction, blocking nerve-muscle transmission.
