Hyperhidrosis Botox — PECHE Clinic, Gangnam Station
Injected directly at the sweat glands of the underarms, hands, or feet, to reduce sweating at that site · 50- and 100-unit configurations · Right by Gangnam Station Exit 4
Hyperhidrosis Botox
Hyperhidrosis Botox places botulinum toxin in many small, shallow injections across the skin where you sweat heavily, reducing the amount of sweat produced at that site. It's performed on the underarms, hands, and feet, and PECHE Clinic runs it in 50-unit and 100-unit configurations.
▲ A vertical cross-section of underarm skin — from the top: epidermis, pink dermis, yellow subcutaneous fat. The thread-like coils within the dermis are sweat glands, and the duct carrying sweat up from each gland spirals to a sweat pore at the surface. Fine needles enter at even spacing, and the teal tint is the product spread around the glands
A sweat gland works on the nerve's "release sweat" signal. Botulinum toxin reduces the release of that signal, so the glands at the injected site do less. The American Academy of Dermatology likewise describes this treatment as one that temporarily reduces the amount of sweat produced at the injected site.
When to Consider It
- Your underarms soak through and mark your clothes even when you're not nervous
- Sweaty hands dampen papers and documents, and handshakes make you self-conscious
- Your feet sweat enough that your shoes always feel damp
- Sweat dictates the colors you can wear, regardless of season
- Topical products don't get you through the day
If odor, rather than the amount of sweat, is the main concern, that calls for looking at treatments with a different goal. Less sweat can mean less odor, but this isn't a treatment that removes odor itself.
Underarms and Hands or Feet Differ From the Skin Up
Even with the same condition, the skin's structure differs by site — and with it, how the injections feel and what to watch for.
▲ The two types of skin shown side by side in cross-section — on the left, the underarm: a thin epidermis, hairs, and sweat glands spaced apart. On the right, the palm: a far thicker hardened outer layer, no hair, and sweat glands packed much more densely
The palms and soles have a thick hardened outer layer (the stratum corneum) and sensitive nerves, so the same needle feels more painful there. And with sweat glands packed more densely, more points are needed.

How It's Done
1. Consultation and range check We confirm where, and how widely, the sweating occurs, and set the total needed (50 or 100 units).
2. Disinfection The treatment area is disinfected.
3. Numbing An ice pack dulls the sensation before we start.
4. Injection A very fine needle places divided doses at even spacing in the skin's shallow layer — the goal is to reach the sweat-gland depth evenly across the area.
5. Aftercare guidance We go over what to follow for the day, and when the results will show.
Results and Recovery
| Item | Details |
|---|---|
| Where it acts | The sweat glands deep in the dermis — a depth that doesn't target muscle |
| Amount per session | 50–100 units — a unit is how the drug's dose is measured · varies with the area's size and how heavily it sweats |
| When results show | Sweat starts decreasing from days 3–7, clearest at week 2 — the signal doesn't cut off at once; it tapers over several days |
| How long it lasts | 3–6 months |
| Repeat interval | Set within the 3–6 month window, watching how much of the sweating returns — some people time it to the sweatier seasons |
| Pain | Each point is a light, shallow prick, but the points run in sequence, so the stinging repeats — on the hands and feet, where the outer layer is thick and the nerves sensitive, it feels more painful |
| Pain control | An ice pack dulls the sensation before we start |
| Downtime | The marks at the injection points settle within 1–2 hours · bruises, if any, fade within 3–7 days |
| For the day | Don't lie down for 4–6 hours · skip saunas, hard exercise, and massaging the treated area — all to keep the product from spreading beyond where it was placed |
| If treated on the hands | A temporary feeling of less strength in the fingers is possible — if your work demands fine hand control, tell us in advance |
Sweating doesn't stop completely. This treatment greatly reduces the sweat at the injected site — outside that range, nothing changes.
Expected Reactions and Possible Side Effects
Common, temporary reactions — part of the normal response:
- Marks at the injection points, settling within 1–2 hours
- Bruises, if any, fading within 3–7 days
If treated on the hands: a temporary feeling of less strength in the fingers is possible. It returns with time — and if your work demands fine hand control, we adjust the timing or suggest starting with the underarms.
Anything beyond this is uncommon. If a reaction lasts longer than expected or worsens, contact us and we'll check it with you.
What We Check Beforehand
If any of these apply to you, let us know during your consultation. We postpone or adjust the timing.
- Pregnancy or breastfeeding
- Conditions affecting the point where nerves meet muscles, such as myasthenia gravis — the very site where botulinum toxin acts, so symptoms could worsen
- Medications that affect nerve–muscle signaling (including some antibiotics)
- Work that demands fine hand control (playing an instrument, precision handwork) — for hand treatment, timing is adjusted
- Sweating that began suddenly, or comes with other symptoms such as night sweats — the cause has to be confirmed first
- Inflammation or wounds at the injection site
- Aspirin or blood thinners (anticoagulants) — bruising can be heavier, so tell us in advance and we'll plan for it
- Botulinum toxin received elsewhere recently — tell us when, with which product, and how much, and we'll recalculate the total amount given in one session and the interval to your next treatment
How PECHE Clinic Does It
Each site is planned differently. The underarms and the hands or feet differ in skin thickness and in how densely the glands cluster. The depth, the number of points, and their spacing are set not by feel but by standards built from over 90,000 treatments and the range we confirm with you.
We offer four botulinum toxin products. Botulinum toxin is a substance produced by bacteria. The bacteria send it out wrapped in other proteins to keep it intact — but only the core inside produces the effect; the wrapping plays no part in it. The core is identical across all four products; what differs is that some products keep the wrapping, and some strip it away to leave only the core.
| Product | Made by | Protein wrapping | Albumin (storage aid) |
|---|---|---|---|
| Newlux | Medytox, Korea | Kept | Used |
| Coretox | Medytox, Korea | Stripped away | Not used |
| Xeomin | Merz, Germany | Stripped away | Used |
| Allergan Botox | AbbVie, USA | Kept | Used |
What keeping or stripping the wrapping means. The wrapping protects the core — but it also means foreign proteins unrelated to the effect enter your body along with it. Repeated over the years, your body can come to recognize and respond to those proteins — and then the same dose may not work as well as it once did. The difference grows the larger the amount going in at once, and the more years you continue. Hyperhidrosis takes 50–100 units per session and tends to be repeated season after season — so we look at whether you're also having facial treatments, and your plan ahead, together with the product.
Albumin is a common protein naturally present in human blood. It keeps the core from degrading while the drug is stored as a dried powder — and Coretox does without it too.
We open the genuine product in front of you — and you can watch it being dissolved through the glass wall, too. Botulinum toxin doesn't keep long once dissolved, so it's stored as a powder and dissolved in saline just before treatment. The more diluted it is, the larger its volume — and the wider it spreads. In a treatment spread across a wide area in many points, the dilution sets how much range each point covers. You see which product is opened right in front of you, and the dissolving itself is visible through the glass wall from the waiting area.

We tell you first what it can do — and what it can't. Sweating doesn't stop completely, and nothing changes outside the injected site. If you're treated on the hands, we also tell you before starting that an early feeling of less hand strength is possible. We don't push same-day payment or packages — you're welcome to come in just for a consultation.

FAQ
Q1. Who performs the treatment? A: PECHE physicians who all work to the same injection standards, built from over 90,000 documented treatments. In hyperhidrosis, the result depends on dividing many points evenly across a wide area — and on the hands, where muscle sits close, the depth matters — so that judgment is made by these standards, not by feel.
Q2. Won't the blocked sweat just come out somewhere else? A: The action stays at the injected site. Treating the underarms doesn't make the rest of your body sweat more.
Q3. Will my hands lose strength? A: In the palm, small muscles that move the fingers sit close beneath the sweat glands — so if a little of the product spreads, an early feeling of less strength in the fingers is possible. It returns with time, but if your work demands fine hand control, we suggest adjusting the timing or starting with the underarms.
Q4. Will the sweating stop completely? A: It doesn't stop completely. The sweat at the injected site decreases greatly, then gradually returns over 3–6 months. Some people schedule it ahead of summer.
Q5. What should I look for when choosing a clinic? A: Whether they set the depth and point spacing differently for the site you're treating, and whether they tell you in advance about discomforts like the hand-strength change. The underarms and the hands or feet differ from the skin up — inject them the same way, and the results and discomforts won't be the same.
