How does Botox work for hyperhidrosis?
Hyperhidrosis (excessive sweating) can cause discomfort in many, but injecting Botulinum toxin (one brand name Botox) has been said to provide relief. ‘Botox has been FDA (Food and Drug Administration) approved since 2004 for the treatment of severe primary axillary hyperhidrosis in patients unable to obtain relief with anti-perspirants,’ explains Dr Mairead Browne, Aesthetic Specialist and The Skin Nerd Health & Wellness Panelist. ‘It causes an 82-97% reduction in sweating, with results lasting six months on average.’ Current evidence shows that repeated treatment with Botox is safe and effective and compensatory sweating has not been shown to be a concern.’ So how does this work? ‘Onabotulinum A temporarily blocks the secretion of the chemicals/ nerve signals responsible for activating the sweat glands.’ Side effects are said to be minimal, with mild discomfort or bruising post treatment that resolves quickly, ‘We are injecting superficially, so not working on the muscles. It is more diluted for treating excessive seating and on average 15 injections per armpit.’ If you do decide to take this option, do discuss it with your GP first and always follow post-injection advice, including avoiding exercise and the wearing of antiperspirant 24 hours prior and 48-hours post treatment.
