This is a condition characterised by excessive sweating. Sometimes the cause is unknown, and when other medical treatment have not helped, the use of botulinum toxin in small multiple injections over the area of the armpit (axilla) reduces the production of sweat to a minimum. The treatment can also be used on other areas of the body including the scalp. The skin is cleansed and multiple tiny amounts of product are placed under the surface of the skin, which results in non-operation of the sweat glands.

As with all botulinum toxin treatments, the effect has a lifespan of 3-4 months but can easily be repeated.
