Botox

Botulinum toxin “blocks” the release of acetylcholine (a chemical messenger released by nerve cells), which causes the muscle cells to contract. Thus, muscle contraction is reduced and wrinkles are considerably smoothened for as long as the effects of the treatment last. 

It can be used on forehead lines, frown lines (glabella), around the eyes (“crow’s feet”) and, in special cases, on upper and lower lip lines and neck.
