Botulinum toxin (Dysport, Vistabel, Botox and other formulas) is used on different parts of the face and causes temporary muscle paralysis where it is injected. The wrinkles are thus reduced and made less distinct. It can also be used in the under-arm, foot, or palm areas to reduce sweating. It is applied with a thin needle with several pierces into the desired area. The effect is usually visible after around four days and reaches its peak at around two weeks. The results last for four to six months.
