Hyperhidrosis is the medical term used to describe excessive sweating, whereby the body produces more sweat than is needed to regulate its temperature. It is a common and often embarrassing problem that affects 1% of the population in both men and women.
The underarms are the most common site where excessive sweating is problematic. The palms of the hands, soles of the feet and forehead can also be treated.
The glands which produce sweat are supplied by the same type of nerve ending that supplies muscles in the face which cause wrinkles. Using a very fine needle, small quantities of the Anti-wrinkle product (Botulinum Toxin A) are injected into 15 - 20 places about 1.5 - 2cm apart and spread evenly over the armpit so that as many sweat glands as possible are blocked. The product works by blocking nerve transmissions that stimulate the sweat glands, resulting in reduced sweating. An anaesthetic cream can be applied before the treatment to reduce discomfort.
You will notice a reduction in sweating within 4-5 days and results can last for 6-8 months.
As with any injection there may be side effects but they are uncommon. They include redness, swelling tenderness, and bruising at the injection sites. Very occasionally the treatment may not work.
The procedure takes approximately 30 minutes to perform. You may experience some discomfort in the form of mild tingling and bruising around the injection sites for 2 to 3 days following treatment. It is important to note that the treatment may not completely stop sweat production but can reduce symptoms dramatically.
