Excessive underarm sweating, also known as axillary hyperhidrosis, can be a major burden and embarrassment for many. If standard topical treatments have failed, you may benefit from having muscle relaxant injections into the armpit area. These injections which are the same as those used for facial cosmetic procedures to treat frowns and wrinkles, work by blocking the release of a chemical called acetylcholine, so that you sweat less. Part of the cost of the treatment is covered by Medicare. This procedure is done in our Dulwich rooms.
