Yes. Treatments are safe when performed by trained dermatologists and tailored to sensitive areas.

Avoiding spicy food, caffeine, and wearing breathable clothes may reduce triggers, but medical treatment is often required.

Mild redness, dryness, or temporary weakness (in case of palm injections) may occur but are generally short-lived.

Most patients need 1–2 sessions depending on the procedure, with periodic follow-ups for sustained relief.

Hyperhidrosis is a recognised medical condition caused by overactive sweat glands, not by poor hygiene. Primary hyperhidrosis has a genetic basis, with sympathetic nerve overactivity driving glands to produce sweat far beyond what thermoregulation requires. People with this condition may sweat four to five times more than normal, regardless of temperature or activity.

Most patients experience significant sweat reduction for six to nine months after a single botulinum toxin session, though some report effects lasting up to twelve months. The duration varies based on the dose administered, the treated area, and individual metabolism of the toxin.

Certain foods do influence body odour through metabolic byproducts excreted in sweat. Cruciferous vegetables, garlic, onions, spicy foods, and alcohol can intensify odour in susceptible individuals. Red meat consumption has also been linked to stronger body odour in some studies.

Compensatory sweating — increased sweating in untreated areas — is primarily associated with surgical sympathectomy, not with botulinum toxin or iontophoresis. These non-surgical treatments target the glands locally without disrupting the sympathetic nerve chain, so the risk of compensatory sweating is minimal. When botulinum toxin wears off, sweating returns to its previous level in the treated area but does not increase elsewhere.
