\r\n\r\nHyperhidrosis treatment in Abu Dhabi at House of Skincare uses botulinum toxin injections to stop excessive sweating at its source \u2014 the overactive sweat glands. Hyperhidrosis is a medical condition in which the eccrine sweat glands produce far more sweat than the body needs for temperature regulation. It affects the underarms, palms, soles, and scalp, and can cause significant social and professional disruption regardless of temperature or activity level. Dr. Khadija Al Zaabi, DOH-licensed Consultant Dermatologist with more than 21 years of clinical experience, treats hyperhidrosis at House of Skincare on Yas Island with a precise, clinically validated injection protocol.\r\n\r\nBotulinum toxin type A works differently in hyperhidrosis than in wrinkle treatment. Sweat glands are controlled by sympathetic nerve fibres that release acetylcholine as their neurotransmitter, just as motor nerves do at muscle junctions. When botulinum toxin is injected into the skin overlying an area of focal hyperhidrosis, it binds to the nerve terminals serving the eccrine glands and blocks acetylcholine release. The glands receive no signal to produce sweat. The result is a dramatic, localised reduction in sweating that has no effect on the body’s ability to thermoregulate through other skin surfaces.\r\n

Why House of Skincare?

\r\nHouse of Skincare is a specialist dermatology and aesthetic clinic on Yas Island, rated 4.9 stars by over 490 patients on Google. Dr. Al Zaabi holds a DOH licence as a Consultant Dermatologist, which means hyperhidrosis treatment here sits within a clinical framework \u2014 not a beauty context. A proper assessment rules out secondary hyperhidrosis (caused by thyroid conditions, medication, or other systemic causes) before treatment begins. The injection grid is mapped to the affected skin area using a starch-iodine test where needed, ensuring precision and avoiding over- or under-treatment.\r\n

Treatment Areas

\r\nAxillary hyperhidrosis (underarms): The most common presentation. Botulinum toxin is injected in a grid pattern across the entire axillary vault \u2014 the hollow of the underarm. Each session involves fifteen to twenty injection points per side. The treatment is well-tolerated with topical numbing cream applied beforehand. Results are pronounced: most patients experience a 80 to 90 percent reduction in underarm sweating within two weeks.\r\n\r\nPalmar hyperhidrosis (hands): Sweaty palms affect handshakes, grip, keyboard use, and can cause significant social anxiety. Treating the palms requires a nerve block or ice anaesthesia because the density of nerve endings makes the area more sensitive. Results are highly effective, though duration may be slightly shorter than axillary treatment at four to five months on average.\r\n\r\nPlantar hyperhidrosis (feet): Excessive foot sweating leads to discomfort, skin maceration, and secondary fungal infections. Treatment follows the same principle as palmar hyperhidrosis. Local anaesthesia is used before injection, and the protocol covers the entire plantar surface of the affected areas.\r\n\r\nCraniofacial hyperhidrosis: Some patients sweat excessively on the forehead, scalp, or upper lip. Intradermal injections into these areas follow the same blocking mechanism. The forehead and scalp respond particularly well and the effect lasts six to eight months in many patients.\r\n

The Starch-Iodine Test

\r\nBefore treatment, Dr. Al Zaabi may perform a Minor’s starch-iodine test to map the exact distribution of sweating. Iodine solution is applied to the skin and allowed to dry, then starch powder is dusted over it. In areas where the glands are active, the iodine and starch react in the presence of sweat to produce a dark purple-blue colour. This map guides injection placement and ensures that the full affected zone is covered while avoiding injection into skin that does not need treatment.\r\n

The Procedure

\r\nAn axillary hyperhidrosis session takes twenty to thirty minutes. Topical anaesthetic cream is applied thirty minutes before the injections. A fine needle is used for each point in the injection grid. Most patients describe the sensation as a series of small pinches. For palmar and plantar treatment, a nerve block or ice pack anaesthesia is offered before the procedure. There is no downtime after any hyperhidrosis treatment \u2014 you can return to work and social activities the same day. Avoid strenuous exercise and heat environments for twenty-four hours post-treatment.\r\n

Results: What to Expect

\r\nMost patients notice a significant reduction in sweating within five to seven days, with the full effect established by two weeks. For axillary hyperhidrosis, results typically last between six and nine months. Palmar and plantar results last four to six months on average. Some patients find that results extend progressively with repeated treatment cycles as the sweat glands respond to regular denervation. Maintenance treatments at the appropriate interval keep the condition well controlled throughout the year.\r\n

Who Is a Good Candidate?

\r\nBotox for hyperhidrosis is appropriate for adults with primary focal hyperhidrosis \u2014 sweating limited to specific body sites that is not caused by an underlying medical condition. You are a suitable candidate if your sweating is bilateral (affects both sides equally), occurs at least once a week, began before the age of twenty-five, has a family history, and disrupts daily activities. Patients who have already tried prescription antiperspirants without adequate control are strong candidates. Botox is not appropriate during pregnancy or breastfeeding, or if you have certain neuromuscular conditions. Dr. Al Zaabi will assess your medical history at consultation to confirm suitability.\r\n

Comparing Options for Hyperhidrosis

\r\nPrescription-strength aluminium chloride antiperspirants are a first-line approach for mild cases but cause skin irritation in many patients and lose effectiveness over time. Oral medications (anticholinergics) reduce sweating but carry systemic side effects including dry mouth, urinary retention, and blurred vision. Iontophoresis is effective for palmar and plantar hyperhidrosis but requires frequent sessions at home and works only while maintained consistently. Botulinum toxin sits in a different category: a clinic-administered treatment that provides months of reliable control with no systemic effects and no daily maintenance requirement. For moderate to severe hyperhidrosis, it offers the best balance of efficacy, tolerability, and convenience.\r\n

Combining with Other Treatments

\r\nHyperhidrosis treatment can be combined with any other dermatological or aesthetic procedure at House of Skincare. Patients frequently schedule a Botox session for facial wrinkles and hyperhidrosis in the same visit. There is no clinical reason to separate these.\r\n\r\n
