Overview
Hyperhidrosis is excessive sweating beyond what thermoregulation requires. Primary focal hyperhidrosis is caused by overactive sympathetic stimulation of eccrine sweat glands, and it is a genuine medical condition with real effects on clothing, work, and social life. Botulinum toxin treats it directly at the mechanism: it blocks acetylcholine release at the neuroglandular junction, so the nerve can no longer signal the sweat gland to produce sweat.
Dr. Zaks treats axillary (underarm) hyperhidrosis and craniofacial hyperhidrosis of the forehead and scalp. Injection sessions take approximately 15 to 20 minutes, and relief typically lasts 6 to 12 months before retreatment is needed. Topical options — Sofdra® (sofpironium) and Qbrexza® (glycopyrronium) cloth — are used alone. Both are topical anticholinergics that reduce sweat production at the gland.
Areas and Options
Axillary (Underarm) Hyperhidrosis
The most commonly treated area. A grid of small intradermal Botox® injections dramatically reduces underarm sweating and the clothing staining that comes with it.
Craniofacial Hyperhidrosis
Excessive sweating of the forehead and scalp, treated with carefully placed superficial injections to reduce sweating while preserving normal expression.
Sofdra® (Sofpironium)
A topical anticholinergic that reduces sweat production at the gland — an option for patients who prefer to begin with topical therapy.
Qbrexza® (Glycopyrronium) Cloth
A pre-moistened medicated cloth applied to the treatment area, blocking the cholinergic signal that stimulates sweat glands.
Duration of Relief
Botox® treatment typically provides 6 to 12 months of relief per session, after which the treatment can be repeated.
Medical Evaluation First
Dr. Zaks confirms primary focal hyperhidrosis and screens for secondary causes, including thyroid disease and medication effects, before treating.
The Treatment Experience
Evaluation
Dr. Zaks confirms the diagnosis, defines the affected areas, screens for secondary causes, and reviews which treatments you have already tried.
Injection — 15 to 20 minutes
Multiple small, very superficial injections are placed evenly across the affected area with a fine needle, based on Dr. Zaks's clinical assessment of each patient. Most patients tolerate this well.
Onset and retreatment
Sweating typically decreases within several days to two weeks. Relief usually lasts 6 to 12 months, and treatment is repeated when the effect wears off.

Frequently Asked Questions
Which areas do you treat?
Axillary (underarm) hyperhidrosis and craniofacial hyperhidrosis of the forehead and scalp. Dr. Zaks does not treat palms or feet in this practice.
How long does the treatment take?
Approximately 15 to 20 minutes.
How long does relief last?
Typically 6 to 12 months per treatment session, after which the injections can be repeated.
How does Botox® stop sweating?
It blocks acetylcholine release at the junction between the nerve and the sweat gland, so the nerve can no longer signal the gland to produce sweat. It addresses the mechanism, not just the symptom.
What are Sofdra® and Qbrexza®?
Both are topical anticholinergic medications that reduce sweat production at the gland. Qbrexza® is a pre-moistened medicated cloth containing glycopyrronium; Sofdra® contains sofpironium. Either can be used alone or with injection therapy.
Does it hurt?
The injections are very superficial and performed with a fine needle. Most patients tolerate them well.
Can I use topical options instead of injections?
Yes. Sofdra® and Qbrexza® are topical anticholinergic options used on their own. They reduce sweat production at the gland and are a good choice for patients who prefer to start without injections.
Will I stop sweating everywhere?
No. Treatment is limited to the mapped area, and normal thermoregulatory sweating continues elsewhere on the body.
