How does Botulinum toxin work?

As the muscles that cause facial expression work, over time this results in the development of frown lines, forehead lines and/or crows feet. Injecting Botulinum toxin into the affected area temporarily paralyses the underlying muscles responsible for wrinkling, giving the face a more relaxed and pleasant appearance. The wrinkles become smoother or disappear altogether.

When and how long does the Botulinum toxin work?

The initial effects of the treatment become visible within 48 to 72 hours. The maximum effect is reached after about 7 to 14 days. The facial expression will become more relaxed. The overall result is very natural. The effect of the treatment generally lasts about 4 months. Re-treatment is then required.

Side effects

Botulinum toxin administered for wrinkle correction by injection is generally a safe and effective treatment method. Nevertheless, certain side effects can occur, but like the intended treatment effects, they are mostly temporary.
