If sweating runs your wardrobe, your handshakes, or your makeup — a precision dose of neurotoxin can quiet the sweat glands in the treated area by 82–87% for 6 to 14 months. No surgery, no daily pills, no clinical-strength antiperspirant routine.
Hyperhidrosis is “focal” — it tends to concentrate in specific areas rather than affecting the whole body. The good news: we can target just those spots. The rest of your body keeps regulating temperature normally.
The most common — and most studied — area for treatment. Sweat marks through shirts, dress code anxiety, deodorant that doesn't keep up. FDA-approved indication for botulinum toxin.
Wet handshakes, smudged ink, the constant towel-on-the-desk. Palmar treatment is one of the most life-changing — clients describe the dry palm feeling as “a different reality.”
Slipping in dress shoes, sweat-stained sandals, foot odor that doesn't respond to powders or socks. Treatment dries the feet and quiets the bacterial chain that follows.
The sweat that ruins blowouts, soaks roots in 10 minutes of summer heat, and shows up in the most visible place during a workout or stressful meeting.
The makeup-melting forehead glow that's not really a glow. Carefully dosed to avoid affecting the brow position — relief without flattening expression.
The little “dewdrops” that show up across the nose bridge and above the upper lip — common, frustrating, and very treatable with a small, precise dose.
Sweat glands aren't broken in hyperhidrosis. The wiring is. Your nerves send the “sweat now” signal too readily — sometimes for no apparent reason. Botulinum toxin doesn't damage the gland; it temporarily quiets the messenger.
Botulinum toxin temporarily blocks the release of acetylcholine — the same neurotransmitter that triggers muscle contraction, but also the one that activates eccrine sweat glands. Without the signal, the gland sits idle. The skin in the treated area stays dry.
Treatment is delivered as a grid of tiny intradermal injections covering the affected zone. Because we're treating skin-level sweat glands and not deep muscle, the injection technique is different from cosmetic Tox — shallower, more sites, ultrafine needles. For underarms or palms we sometimes map the sweat zone with a starch-iodine test so we don't miss the edges.
Sweat regulation everywhere else continues normally — your body still cools itself; it just stops dumping it all in the underarms, the palms, or the hairline. The treatment is local, reversible, and repeatable.
Products we use: Xeomin (incobotulinumtoxinA) and Jeuveau (prabotulinumtoxinA) — both FDA-approved botulinum toxin type A neuromodulators in the same therapeutic family as Botox. Botulinum toxin is FDA-approved for underarm hyperhidrosis; treatment of palms, soles, scalp, and face is off-label but well-established.
Map the sweat zone, numb the area (for palms / soles), and place a grid of tiny intradermal injections. Walk out the same day — light bandage if any.
Most clients notice the treated area starting to stay dry within the first week. Underarm treatment tends to respond first.
Peak dryness in the treated area. Touch-up at this point if a small zone was missed. Sweat-stained shirts become a non-issue.
The effect gradually fades. Most clients return once or twice a year. Repeat treatments are often the same dose or slightly less.
This is one of the most life-impact-per-dollar treatments we offer. Clients often describe the change less in terms of skin and more in terms of freedom.
Botulinum toxin for hyperhidrosis has been studied for over 25 years, and is one of the most well-established off-cosmetic indications. The summary below is a starting point — every linked source is from a major medical institution or peer-reviewed body.
Mayo Clinic's overview describes botulinum toxin injections as an established second-line treatment for excessive sweating that has not responded to clinical-strength antiperspirants. Effects typically last 6 to 12 months.

Visit Sweathelp.org →Hundreds of randomized trials and reviews — most reporting 82–87% reductions in sweat output in treated areas, with durable improvements in quality-of-life scores and minimal systemic side effects.
Browse PubMed literature →Clinical studies report an 82–87% reduction in sweating in treated areas. Most clients describe the treated area as feeling dry — even in situations that previously triggered heavy sweating, like nerves, heat, or exercise.
Results begin within 4 to 7 days and reach full effect at the 2-week mark.
Effects typically last 6 to 14 months — much longer than the 3-to-4-month duration of cosmetic neurotoxin.
Underarm treatment is often on the longer end (8–14 months). Palms and soles tend to be shorter (6–9 months). Most clients return once or twice a year.
Underarm treatment is very tolerable — the skin there isn't very sensitive and we use ultrafine needles. Most clients describe it as mild pinches.
Palms and soles are more sensitive; we use topical numbing, ice, and a vibration tool to make them comfortable. Most clients describe palm and sole treatments as “briefly uncomfortable but absolutely worth it.”
Typical doses: underarms use about 50 units per side; palms use 50–100 units per hand; soles use 75–150 units per foot; scalp varies by coverage area.
Units add up faster than cosmetic treatment, which is why per-unit pricing matters. Full quotes provided at consultation after we map your sweat zone.
Botulinum toxin for underarm (axillary) hyperhidrosis is FDA-approved and is sometimes covered by insurance — but usually only after step therapy with prescription antiperspirants (Drysol) and oral medications.
Most clients pay out of pocket for the convenience and speed. Treatments for palms, soles, scalp, and face are considered off-label and rarely covered. We can provide documentation if you'd like to submit for reimbursement.
Compensatory sweating is a well-documented complication of surgical sweat treatment (ETS surgery) — but it's rare with botulinum toxin.
Because the treatment is localized and reversible, the body does not typically reroute sweating elsewhere. If you do notice mild changes, they resolve as the effect wears off.
Yes. Only the treated area is affected. The rest of your body's sweat glands continue to function normally for thermoregulation.
People who treat just their underarms still sweat normally during exercise everywhere else.
We use Xeomin (incobotulinumtoxinA) and Jeuveau (prabotulinumtoxinA) — both FDA-approved botulinum toxin type A neuromodulators in the same family as Botox. For hyperhidrosis the mechanism, efficacy, and longevity are clinically equivalent.
If you came in searching for “Botox for sweating,” you're in the right place. We'll recommend the right product at consultation.
Most clients notice reduced sweating within 4 to 7 days, with peak effect at 2 weeks. We schedule any minor touch-ups at the 2-week follow-up if a small area was missed.
Generalized sweating, sudden-onset sweating, or sweating accompanied by other symptoms (night sweats, weight loss, fever) needs a medical workup first — there are underlying causes that should be ruled out before aesthetic treatment. See your primary care physician.
Primary focal hyperhidrosis — localized to underarms, palms, soles, scalp, or face, present since teenage years — is the indication that responds best to botulinum toxin.
