Botulinum toxin for excessive sweating

Hyperhidrosis Botox

Sweat that soaks a shirt before a meeting starts is not a willpower problem. Botulinum toxin interrupts the signal that tells sweat glands to switch on — temporarily, in the area treated.

About

What is hyperhidrosis botox?

Hyperhidrosis botox is a series of shallow botulinum toxin injections placed across a sweat-prone area such as the underarms. Sweat glands are switched on by a nerve signal; the toxin temporarily blocks that signal where it is placed, so the treated area produces less sweat while the effect lasts. It does not change the glands themselves, and the rest of your body sweats normally.

This is a management treatment. Excessive sweating is interrupted in one mapped area, for a period of time, and returns as the effect wears off; the glands themselves are left exactly as they were. What the treatment buys is control during the months you most need it: a Seoul summer, a wedding, an interview season, a job that keeps you in front of people.

Three things stop a booking here. Sweating that began suddenly, that affects one side only, that wakes you at night, or that arrives alongside weight loss and fever is a question for a physician before it is a question for us, and we decline the session until that assessment has happened. Pregnancy, breastfeeding, a neuromuscular condition and blood-thinning medication each change the plan or rule the injection out. And where a clinical-strength antiperspirant has never genuinely been tried, that is the cheaper step that comes first.

Treatment Areas

Which sweat zones we map and treat

Two measurements set the block count: how wide the sweating zone runs, and how heavily it runs. Both are taken at consultation, and neither is inherited from a package.

01

Underarms, the starting zone

The most common request here by a wide margin. A shallow grid covers the damp zone on both sides within one session, and because underarm skin is even and the sweat border marks clearly, this is where the reduction usually reads most uniformly across the area. The block count is stated to you before the first point goes in.

02

Palms and soles share one protocol

Hands that leave damp marks on paper, feet that slide inside a shoe: both are thick, densely supplied skin, so numbing and pacing are agreed with you before anything starts. Palms are dosed conservatively for a specific reason — a temporary sense of weaker grip is a recognised effect where the dose sits near the small muscles of the hand.

03

Forehead and scalp line

Dosing stays deliberately light near the brow. Diffusion beyond the mapped zone here can leave a heavy-feeling eyelid or a few weeks of asymmetry.

How we do it

Marking the sweat border before any dose is drawn

The injection itself is quick. Working out where the sweating zone actually ends is the part that decides whether the reduction comes out even.

STEP 01

Define the zone before you dose

Your director works out where sweating is heaviest and where it stops, from your own account of it, from what the area looks like, and from where marks appear on clothing. Treating a zone that is too small leaves an active fringe, and everyone notices a fringe.

STEP 02

An even grid, kept shallow

Points are placed in a regular pattern just under the skin surface across the mapped zone. Even spacing is what produces an even reduction; clustering the dose leaves dry patches next to wet ones.

STEP 03

Comfort planned in advance

Underarms are usually straightforward under topical numbing. Palms and soles are more sensitive, so comfort measures and pacing are agreed with you before the first point, and the session can be paused at any stage without argument.

Sweating serves a purpose, so the target is a manageable reduction across the mapped zone and never the largest dose an area will absorb. The risks are named at consultation in plain order: small bumps and redness at the points, an occasional bruise, uneven reduction in the first days, a mild increase in sweating outside the treated zone, and — where the dose sits close to working muscle, as it does in the palm — temporary weakness in that muscle.

Why sweat work is director-performed here

01 — THE FULL ARSENAL

Sweating is one of six toxin jobs here

The same molecule is used at Dear Clinic for wrinkle work, square jaw, skin botox, salivary gland, sweat zones and trapezius. Two tiers are stocked, Korean and premium imported; the tier is your choice at the same mapped block count.

02 — DIAGNOSIS FIRST

The EVE Muse scan comes before the sweat map

Diagnosis opens with EVE Muse 3D imaging under five light sources and AI analysis, and continues into a director consultation that works through your history, your medication and the pattern your sweating actually follows through a week — including the question of whether an injectable is the right answer at all, which is a question we answer both ways.

03 — DIRECTOR-PERFORMED

The hand that marks the zone places the points

A wide grid over sensitive skin rewards one consistent hand. Your session is director-performed, so the spacing you were shown on the map is the spacing that reaches your skin.

Pricing

How much does hyperhidrosis botox
cost in Seoul?

At Dear Clinic in Cheongdam, hyperhidrosis treatment is priced in 50-unit blocks: ₩150,000 (≈ $105) per 50 units with Korean botulinum toxin, and ₩600,000 (≈ $430) per 50 units with premium imported toxin. How many blocks your plan needs depends on the size of the area and how heavily it sweats, so your total is confirmed at consultation — before anything begins, at the same published rate we charge local patients.

Every planEVE 3D + AI diagnosis · director consultation · aftercare guidanceincluded

Priced by the unit, because sweat zones are not the same size. A wide, heavily sweating underarm and a small forehead zone do not need the same amount, and a flat "per area" figure hides that gap in one direction or the other. Blocks are counted openly, you see the count before treatment, and unused blocks are not charged for. Published rates as of September 2026; KRW is what you pay, USD is shown for reference. Every published rate is on our price list, and if you are visiting Seoul on a short trip, our 365-day schedule covers Sundays and public holidays.

Caution

Aftercare for treated sweat zones

Small bumps and mild redness at the injection points settle within a few hours.
Leave the area alone for the rest of the day — no massage, no shaving, no deodorant on treated underarms.
Skip the gym, saunas and hot baths for a couple of days while the effect establishes.
Sweating may reduce unevenly at first; judge the result at your review and not on the morning after.
Contact us about any unusual weakness, spreading numbness or anything that concerns you — aftercare follow-up is part of the treatment.

FAQ

Hyperhidrosis botox, answered

Is hyperhidrosis botox worth it?
For people whose sweating dictates what they wear and how they behave at work, it is one of the few options that changes daily life without surgery. What you are buying is temporary control inside one mapped area. If a clinical-strength antiperspirant has not genuinely been tried, or the pattern suggests a medical cause, we say so before taking a booking.
How does botulinum toxin stop sweating?
Sweat glands are activated by a nerve signal. Botulinum toxin temporarily blocks the release of the chemical messenger that carries that signal in the area where it is injected, so those glands are not switched on as strongly while the effect lasts. Glands outside the mapped zone keep working normally, and normal signalling returns as the toxin wears off.
How much does hyperhidrosis botox cost in Seoul?
At Dear Clinic it is ₩150,000 (≈ $105) per 50 units with Korean botulinum toxin and ₩600,000 (≈ $430) per 50 units with premium imported toxin. The number of blocks depends on the area's size and how heavily it sweats; the count is agreed with you at consultation, and locals and international visitors pay the same published rate.
How many units will I need?
The mapped zone decides it. A broad, heavily sweating underarm takes more than a small forehead zone, so your director measures the area, states the block count and the total before treatment, and does not charge for blocks that go unused. If the zone turns out smaller than it looked, the quote goes down with it.
When does it start working, and how long does it last?
It is not instant. Sweating reduces over the days after the session as the effect establishes, and it may settle unevenly at first before evening out. Duration varies with the area, the dose and the individual, so we give you a realistic expectation for your own plan at consultation instead of a single published number, and confirm it at review. That build-up is also why a wedding or a presentation should be booked with weeks of margin, never the day before.
Does it hurt?
Underarm treatment is generally well tolerated under topical numbing — a series of quick shallow pricks. Palms and soles carry more nerve endings, so comfort measures and pacing are agreed with you in advance. Say the word at any point and the session pauses; there is no reason to push through.
Will I sweat more somewhere else instead?
Some people do notice slightly more sweating in untreated areas. It is usually mild, and it is raised with you before the first session so it is not a surprise afterwards. It is also one reason the treated zone is drawn to the sweat border and not expanded as far as the skin will take.
Is there downtime?
Practically none for underarm treatment; most people go straight back to work. Small bumps and redness at the points settle within hours. Skip deodorant, shaving, the gym, saunas and hot baths for a day or two. Hands and feet can feel tender for a short while, so a palm session is better placed on a quiet afternoon than before a piano recital.
Will it affect my grip or hand strength?
Palm treatment sits close to small muscles that control fine hand movement, so a temporary feeling of reduced grip strength is a recognised possibility. That is precisely why palms are dosed conservatively and performed by a director here. If your work depends on fine hand control — musicians, surgeons, athletes — tell us at consultation so it can be weighed properly.
Can I have it on the same day as my consultation?
Usually yes, if your history and examination raise nothing that needs assessing first. Diagnosis and consultation take about 30 minutes, the sweat map is drawn in the same visit, and the injection can follow immediately. Dear Clinic is open 365 days a year, including Sundays and public holidays, so a single free afternoon in Seoul is enough for a first underarm session.
Do men have this treatment too?
Frequently. Underarm and palm treatment are among the more common male requests here, usually driven by presentations, client meetings and interview season. A male underarm zone tends to map larger, so the block count is often higher; the published rate per 50-unit block is identical either way.
What do international visitors pay, and how do I book?
The same published rates as residents, in KRW, with USD shown for reference only. Send the consultation form with your travel dates and say which zones sweat and how heavily; that is enough for us to estimate the block count and quote a total before you fly. We reply in English within one business day and hold the slot without a deposit.

Scientific Evidence

Science behind toxin for sweat reduction — peer-reviewed references

Botulinum toxin type A has been studied and reported in the peer-reviewed literature for decades, from the first clinical applications through international consensus work on injection practice and detailed pharmacological reviews of how licensed products differ from one another. That body of work informs the dilution, depth and dosing discipline our directors apply when treating sweat-prone areas.
