Botulinum toxin is a neurotoxin made by a bacterium called Clostridium botulinum. It is the most powerful toxin discovered to date. The most popular version of this neurotoxin for its use in aesthetics is called Botox.
The injection of botulinum toxin into the muscle through the skin, temporarily eliminates or reduces both expression wrinkles (those that appear when making some movement or gesture with the face) and wrinkles between the eyebrows, neck and " crow's feet”, all of them due, in large part, to the contraction of the underlying muscles. The toxin temporarily paralyzes these muscles, giving the skin a smooth appearance and the expression softening and rejuvenating.
The effects begin to appear from the seventh day after application and last up to 6 months.
