Botox is a neurotoxin that blocks the transmission of nerve signals to muscles, which causes them to relax. When Botox is injected into the muscles of the face, it reduces muscle activity, thereby reducing the formation of facial wrinkles. This treatment is commonly used to reduce facial wrinkles such as forehead lines, eye lines and crow's feet.
Botox injections are a very safe treatment, but you should tell your doctor if you have any medical problems, especially those related to the nervous system, before getting them. After the injection, you may experience mild discomfort or swelling at the injection site, which usually goes away within a few days.
Note that Botox injections will not permanently remove facial wrinkles. Typically, the effects of the injection last for several months, after which another injection is required to maintain the effect
