Not all botulinum toxin is for anti-wrinkle injections, some are for medical reasons too!
Botulinum toxin injected under the arms can help to reduce excessive sweating. It’s perfectly normal to sweat, but hyperhidrosis is abnormal excessive sweating that’s not necessarily related to heat or exercise. Besides disrupting normal daily activities, this type of heavy sweating can cause social anxiety and embarrassment. Injecting botulinum toxin into the sweat glands under the arms can dramatically reduce sweat in these areas.
It works by blocking a chemical in the body that activates the sweat glands, This will usually happen within two weeks of treatment and the effects can last between six and seven months!
