Excessive sweating Botox is a highly effective and FDA-approved treatment for people suffering from a condition called hyperhidrosis—the medical term for profuse and uncontrollable sweating. It can affect various areas of the body, but the underarms are among the most commonly treated zones. Using Botox® for excessive perspiration allows individuals to regain comfort and confidence in daily life without the constant worry of sweat marks, odour, or the need to change clothes multiple times a day.

Hyperhidrosis, or excessive sweating, is a medical condition where the body produces more sweat than necessary for cooling. This can occur even in cool temperatures or without physical exertion. The most common areas affected include the underarms, palms of the hands, soles of the feet, and head and face.
Botox® for hyperhidrosis works by blocking the nerve signals that stimulate the sweat glands. The active ingredient, botulinum toxin, acts as a neurotoxin, temporarily disabling these nerves. The result is a dramatic reduction in sweat production—without affecting other body functions.
Your treatment for hyperhidrosis begins with a consultation and a medical assessment. Dr. Bela will mark the armpit area using a grid pattern, ensuring the injections are evenly distributed. Around 12 to 15 small injections are given in each underarm, targeting the sweat glands directly.
A fine needle is used to make the procedure more comfortable. The Botox is injected into the skin, just below the surface of the skin, rather than into muscle, making it different from aesthetic Botox treatments. The full treatment involves about 15 minutes from start to finish.
Results from Botox injections for sweating usually begin to appear within three to four days, with full effects developing over 1 to 2 weeks. On average, results last 4 to 6 months, though some clinical studies and patient reports indicate effectiveness up to 7 to 16 months. Repeat injections need to be repeated periodically to maintain control of the excessive sweat.
Yes. While the underarms are the most common area treated, injections for hyperhidrosis can also be used on the palms, soles of the feet, facial sweating, and craniofacial regions. However, treatment on areas like the palm or head and face requires even more expertise and numbing, due to the sensitivity and density of nerves. Dr. Bela will advise on these areas during your consultation.
One common concern is whether treatment for excessive sweating in one area might increase sweating elsewhere. In clinical experience and according to the International Hyperhidrosis Society, Botox does not cause compensatory sweating in other areas of the body. The treatment is localised and does not affect your body’s overall temperature regulation.

Over the years, Dr. Bela has identified multiple melanomas on aesthetic patients—often in areas they hadn’t noticed themselves. In one notable case, during a Botox consultation, he spotted a small but suspicious lesion on a patient’s forehead. When reviewing previous treatment photos, it became clear that the melanoma had gradually developed over time, becoming increasingly visible across sessions. Despite its small size, the lesion was already an early invasive melanoma—but was thankfully detected in time. This case is just one of several examples highlighting how melanoma can remain hidden in plain sight. For this reason, Dr. Bela now offers a discounted mole check for all existing aesthetic patients, making it easier to combine cosmetic care with life-saving early detection.
