Excessive Sweating Treatment (Underarm Botulinum Toxin)

Botulinum toxin injected into the underarms to reduce excessive sweating (axillary hyperhidrosis). By temporarily limiting the nerve signals that switch on the sweat glands, the treatment can noticeably cut underarm wetness for several months. It is a quick, in-clinic procedure carried out by a physician and is popular ahead of summer, weddings or events where underarm sweating is a particular concern.

Excessive underarm sweating treatment uses botulinum toxin to temporarily interrupt the chemical signal that tells the sweat glands to produce sweat. A grid of small injections is placed across each underarm, and over the following days the treated area typically produces much less sweat. It is a well-established option for people whose underarm wetness is not controlled by antiperspirants and who find it affects clothing, confidence or daily comfort. At V Clinic the procedure is performed by a physician and usually takes around twenty to thirty minutes. A topical anaesthetic can be used for comfort, and most people return to normal activities straight away, avoiding heat, saunas and vigorous exercise for the rest of the day. Results generally begin within a few days to a week and commonly last several months — often into a second half-year — before the effect gradually wears off and a repeat is considered. Many patients schedule treatment in late spring so the benefit covers the warmer months. Suitability, the area to be treated and any contraindications are assessed at consultation; the treatment is not carried out during pregnancy or breastfeeding.
