Botulinum toxin is a neurotoxin produced by the bacteria Clostridium Botulinum that has several cosmetic and therapeutic uses. Botulinum toxin A, when injected, blocks the nerve signals that cause muscles to contract. Unlike BT, which is directly used to stop muscle movement, HA fillers are directly injected into the skin to fill wrinkles, depressed, or folded points in the face. It also brings water to the surface of the skin to keep it looking fresh and supple.
