What are the types of hyperhidrosis and where does it occur?
Hyperhidrosis is classified into primary (idiopathic)—the most common form, usually beginning in childhood or adolescence and often with a hereditary predisposition—and secondary, which results from an underlying condition (e.g., hormonal changes) or medication use. It most commonly affects:
- Armpits (axillary hyperhidrosis)
- Palms (palmar hyperhidrosis)
- Soles (plantar hyperhidrosis)
- Face, scalp, or more generalized areas of the body
What are the symptoms and impact on daily life?
Individuals with hyperhidrosis experience persistent skin moisture and sweating without an obvious trigger (such as heat or exercise). This can lead to:
- Difficulty with daily activities: e.g., trouble gripping objects due to sweaty hands
- Frequent skin infections: Constant moisture promotes fungal and bacterial growth (e.g., athlete’s foot, bromhidrosis)
- Psychological burden: Reduced confidence and social or professional discomfort (e.g., handshakes)
- Work-related challenges: It may affect job performance
What is the most effective treatment for hyperhidrosis?
The most modern and effective treatment for primary focal hyperhidrosis is botulinum toxin injection. The toxin temporarily blocks the nerve signals that stimulate the sweat glands, significantly reducing perspiration.
Is botulinum toxin treatment for hyperhidrosis painful?
Treatment with botulinum toxin is painless and non-invasive. It is performed using a topical anesthetic cream and a very fine needle, making the injections well tolerated by most patients. Any discomfort is minimal and temporary.
What are the advantages of treating hyperhidrosis with botulinum toxin?
- High Effectiveness: Up to 95% reduction in excessive sweating
- Approved Treatment: Officially approved by international and national regulatory authorities (e.g., FDA)
- Long Duration: Results last 6–12 months in the underarms and 3–12 months in palms/soles, requiring treatment only 1–2 times per year
- Safe and Reversible: A safe treatment with minimal side effects
- No Downtime: Immediate return to daily activities
How is the treatment procedure performed?
The procedure is simple, quick, and performed in-office:
- Preparation: Application of topical anesthetic cream to the treatment area (underarms, palms, soles)
- Mapping: A special test (iodine-starch test) may be used to precisely identify areas of excessive sweating
- Injection: Intradermal injections of botulinum toxin are administered using a very fine needle at specific points
- Completion: The total procedure takes approximately 30–45 minutes
