Dr. Claudio Wulkan is a specialist in the medical treatment of hyperhidrosis in São Paulo. Excessive sweating is a diagnosis, not a cosmetic complaint — and treating it with botulinum toxin requires mapping the affected area and calculating the units precisely. He has performed more than 10,000 botulinum toxin applications, with four brands of toxin available for armpits, palms, soles and scalp. He is a dermatologist registered under CRM-SP 90.579 with specialist qualification RQE 39.944, graduated in Medicine at UNIFESP — Federal University of São Paulo in 1997, part of the staff of Hospital Israelita Albert Einstein, with around 30 years of practice and more than 300 courses and international congresses attended over the decades.
If you are looking for treatment for hyperhidrosis in São Paulo, you are in the right place: Clínica Wulkan is a family practice founded in 1985, with two units (Jardim Paulista and Osasco) and more than 20 laser and energy-based technologies — technologies Dr. Wulkan also teaches to other physicians — so the plan can combine approaches when toxin alone is not enough. Everything starts with an individual medical evaluation, in a medical environment, that confirms the diagnosis and excludes other causes of excessive sweating.

What hyperhidrosis is and who it affects
Hyperhidrosis is a common but often underdiagnosed medical condition characterized by excessive sweating beyond normal physiological needs. It can significantly impact quality of life, professional activities, social interactions and emotional well-being. Excessive sweating most frequently affects the underarms (axillary), palms (palmar), soles (plantar) and, in some cases, the face or scalp. Symptoms often begin in adolescence or early adulthood and may persist if not properly treated.
Why medical diagnosis comes first
Hyperhidrosis occurs due to overstimulation of the sweat glands by the nervous system, not because of heat or physical activity alone — which is why standard antiperspirants are often insufficient and a medical evaluation by a dermatologist is essential. Accurate diagnosis differentiates primary hyperhidrosis (localized and idiopathic) from secondary hyperhidrosis, which may relate to hormonal, metabolic or neurological conditions. At Clínica Wulkan, hyperhidrosis is treated as a medical condition requiring individualized care, led by Dr. Claudio Wulkan, a board-certified dermatologist with nearly 30 years of practice and a member of the medical staff at Hospital Israelita Albert Einstein.
Treatment options
Treatment for hyperhidrosis varies with the affected area and severity, and may include topical therapies, oral medications, iontophoresis and botulinum toxin injections — considered one of the most effective treatments for moderate to severe cases. Botulinum toxin temporarily blocks the nerve signals that stimulate the sweat glands, giving predictable, long-lasting results and a meaningful improvement in quality of life. The right choice is defined after a complete medical evaluation.

What the science shows
For moderate to severe localized cases, botulinum toxin has strong evidence behind it. A 2025 meta-analysis confirmed its efficacy and safety in primary axillary hyperhidrosis (Meta-analysis, PubMed, 2025). A medical evaluation determines whether this is the best option for your case.
