Excessive Sweating (Hyperhidrosis)

Hyperhidrosis is a condition where the body produces more sweat than is needed for temperature control. It most often affects the underarms, palms, soles of the feet, and face. This can be embarrassing, inconvenient, and socially distressing. Many patients have tried strong antiperspirants without success, not realising that effective medical treatments exist. At DermLab, our Dermatologists provide evidence-based treatments for hyperhidrosis, helping patients live confidently and comfortably.

Symptoms

  • Excessive sweating unrelated to exercise or heat

  • Visible wet patches on clothing

  • Clammy or dripping palms/soles

  • Difficulty with daily activities (shaking hands, holding pens, using devices)

  • Emotional distress, embarrassment, or reduced confidence

Causes

  • Primary hyperhidrosis — no underlying medical cause, usually starts in childhood or adolescence, affects specific areas (palms, soles, underarms)

  • Secondary hyperhidrosis — linked to conditions like thyroid disease, diabetes, infections, or medications; may be generalised across the body A Dermatologist assessment is essential to confirm the type and guide safe treatment.

Treatment at DermLab

  • Prescription antiperspirants — stronger than supermarket brands

  • Prescription medications — tablets to reduce sweating in selected patients

  • Botox® injections — highly effective for underarm and palm sweating, lasting 4–6 months

  • Iontophoresis — a mild electrical current treatment for hands/feet (available in some centres, referral if needed)

  • Treatment of underlying causes — if sweating is secondary to another condition
