What is Hyperhidrosis?

Sympathetic overactivity of eccrine sweat glands producing excessive, socially and functionally disruptive sweating.

Who gets Hyperhidrosis?

About 3–5% of adults. Primary focal hyperhidrosis typically begins in adolescence or young adulthood.

What are the symptoms of Hyperhidrosis?

Visible sweat-through clothing, dripping sweat on hands or feet, skin maceration, and associated social or occupational impairment.

How do you treat Hyperhidrosis?

Prescription-strength aluminum chloride antiperspirants, glycopyrronium wipes, iontophoresis, and in-office botulinum toxin (Botox) injections for durable relief lasting 4–6 months.

How long does Hyperhidrosis take to improve?

Botox injections are a 15-minute in-office treatment with no downtime; sweat reduction begins within 3–5 days.

Clinical Standard

Beyond Antiperspirant.

Primary hyperhidrosis affects up to 5% of the population. The overactive eccrine glands produce sweat far beyond what is needed for thermoregulation—often triggered by stress, social situations, or no trigger at all. Standard antiperspirants are insufficient, and the condition can significantly impact quality of life.

Clinical Sweat Reduction. Our primary intervention is Botox injection directly into the affected area. Botulinum toxin blocks the nerve signals that stimulate sweat glands, reducing sweating by up to 87%. Results last 4-6 months. For patients who prefer topical therapy, we also prescribe clinical-strength antiperspirants and oral anticholinergic medications.

Common Questions

Frequently Asked.

How does Botox treat sweating?

Botox blocks the acetylcholine nerve signals that activate sweat glands. Without the signal, the glands simply stop producing excess sweat.

How long does the treatment last?

Results typically last 4 to 6 months. Many patients schedule treatments twice a year.

Is hyperhidrosis Botox covered by insurance?

Many insurance plans cover Botox for hyperhidrosis when conservative treatments have failed. We provide documentation to support your claim.

Does Botox for sweating hurt?

We use ultra-fine needles and ice or topical anesthesia to minimize discomfort. Most patients tolerate the procedure very well.
