Incheon AirportWhat does underarm botox do for excessive sweating, and how does it work?
It shuts down the message that turns your armpit sweat glands on. The nerves that supply those eccrine glands release acetylcholine, and botulinum toxin blocks that release at the gland, so the sweat response in the treated skin quiets down. Dryness builds over roughly two weeks and holds for about four to seven months before the signal returns and a repeat is considered. At RE:BERRY Gangnam a starch-iodine test maps where you actually sweat first, then the physician places a grid of shallow intradermal points across that zone, and the same doctor stays with your case from the test through your review.
Effects & Progress
Effects & Progress
Blocking the nerve signal to the eccrine glands cuts underarm sweat sharply in the treated skin, so shirts stay dry through a long day and a humid Seoul summer.
The visit is done in one sitting with no wound; travel is fine the same day. Faint redness at the points settles within hours, and the sweat glands are still active until the toxin takes hold.
The first change. Many guests notice sweating dropping by roughly forty to fifty percent as the nerve signal to the glands begins to quiet across the treated skin.
Full effect. Underarm dryness reaches its peak by around two weeks, and a repeat starch-iodine test confirms coverage and flags any small patch that still sweats.
Maintenance period. Dryness holds four to seven months before the nerve signal returns; RE:BERRY will guide the repeat timing that keeps you dry through your next hot season.

Effects & Progress
Heavy underarm sweating comes from eccrine glands that fire whenever a nerve signal reaches them. Underarm botox quiets that signal across the mapped skin, so perspiration in the treated zone drops dramatically at its source. A topical only works at the skin surface for as long as you keep applying it. The result is dry underarms through a long working day and a humid summer, without the constant reapplication a topical needs. Because the coverage follows the blue starch-iodine map, the whole active area is calmed evenly, and the dryness holds for months from a single session before the signal gradually returns.
This is a treatment that works on a nerve's timeline, not instantly. Many guests notice sweating already dropping by roughly forty to fifty percent within the first week, and the full effect settles by around day fourteen as the toxin takes hold at the sweat-gland nerve endings. There is no incision and no recovery that costs a trip; the injections themselves are a short visit. Guests traveling for a specific date are told to plan at least two weeks ahead so the dryness has peaked by the time they need it. Response speed is honestly individual.
The action is deliberately confined to the underarm skin that was mapped and injected. Botulinum toxin works on the nerve endings supplying the eccrine glands in that zone, so the sweat glands elsewhere on your body are unaffected and continue to cool you normally. Some guests worry the body will sweat far more elsewhere to compensate; in practice any such change is usually minor. The physician grids only the blue-mapped area and keeps the treatment to the armpit, so the dryness is targeted and the rest of your normal sweating is left in place.
Underarm botox is a maintenance treatment, and its temporary nature is part of the plan. Dryness typically holds for four to seven months, after which the treated nerve terminals recover their function, the sweat signal returns, and perspiration slowly creeps back. A repeat session restores the effect, and many guests schedule it just before the dryness fades, often timed ahead of each hot season. The physician sets the interval from how long the effect actually lasts for you rather than a fixed calendar, since recovery speed varies by individual.

What Underarm Botox Delivers for Sweating, and When
- A sharp drop in underarm sweat: quieting the nerve signal to the eccrine glands cuts perspiration in the treated skin dramatically, so shirts stay dry through a long day and a Seoul summer
- Mapped, not guessed: the starch-iodine test draws your active zone in blue-black before injection, so the grid covers the skin that genuinely overproduces and not a generic area
- A short, walk-in-walk-out visit: the injections are placed in one sitting with no wound, and a same-day flight home fits a short Seoul trip
- Months of dryness from one session: the effect holds for roughly four to seven months before the signal gradually returns, so a single visit can carry you through a hot season
- Local to the underarm: the toxin works on the sweat-gland nerves in the treated skin, leaving the rest of your body and its normal cooling untouched
- One physician the whole way: the doctor who reads your starch-iodine map places every point and reviews your result, and Spanish-speaking coordinators keep the follow-up clear after you fly home

Underarm Botox vs Antiperspirants vs Sweat-Gland Devices: Matching the Tool to Heavy Sweating
| Criteria | Underarm Botox (RE:BERRY Gangnam) | Prescription Antiperspirant | Energy Sweat-Gland Device |
|---|---|---|---|
| How it works | Blocks the nerve signal that switches the sweat glands on | Plugs the sweat ducts at the skin surface | Heats and reduces sweat glands in the treated tissue |
| Where it acts | The eccrine sweat glands under the mapped skin | The surface of the skin only | Deeper glandular layer of the underarm |
| How dryness arrives | Builds over about two weeks | Nightly application, effect while used | Over sessions as glands reduce |
| How long it holds | Roughly four to seven months per session | Only while applied regularly | Aims to be longer-lasting |
| Downtime | None; same-day flight is fine | Possible skin irritation | Swelling and soreness for days |
| Best when | Sweating is heavy and daily life is affected | Sweating is mild to moderate | You want a longer-term reduction and accept downtime |
Why This Matters
Heavy underarm sweating is a glandular signal problem, and the treatments differ by where they intervene. A prescription antiperspirant works at the skin surface and only while you keep applying it. Underarm botox reaches further back, to the nerve that tells the gland to fire, so a single session quiets the sweat response for months. An energy device instead reduces the glands themselves and asks for more downtime in return. The starch-iodine map at RE:BERRY Gangnam confirms the sweating is truly excessive before botox is chosen.
For guests flying in from Spain and Latin America, timing is half the plan. Dryness takes about two weeks to reach full effect, so booking a few weeks ahead of the hottest stretch means the treatment is working when the humidity peaks. Many pair the visit with a wider Seoul trip in spring, walk out dry, and travel home the same day. The physician sets the plan against your calendar so the effect lands when you need it, not after.
KHIDI's 2025 international patient survey found 41.4% of respondents rank keeping the same doctor throughout as their leading criterion. At RE:BERRY Gangnam the physician who paints and reads your starch-iodine map plans the grid, places every point, and reviews your dryness at follow-up, with no handoff between the person who maps your sweating and the person who treats it.

The Evidence Behind Underarm Botox for Sweating
Sweat from the eccrine glands is switched on by a nerve signal. The sympathetic fibers that supply these glands release acetylcholine, and that chemical messenger is what tells the gland to produce sweat. Botulinum toxin type A prevents the nerve terminal from releasing acetylcholine, so the gland in the treated skin stops getting the message and quiets down. The effect is confined to the small area around each injection point, so the physician maps and grids the whole underarm rather than treating a single spot.
The clearest evidence for this comes from underarm sweating itself. A randomized, placebo-controlled trial of botulinum toxin type A for bilateral primary axillary hyperhidrosis documented a marked, sustained reduction in sweat production against placebo, establishing the treatment as a direct answer to the condition. The broader efficacy and safety of botulinum toxin type A as an injectable have been mapped in large randomized controlled work, and the intradermal, shallow-grid delivery used across the underarm has its own supporting record for treating overactive skin glands. That evidence base is the reason the physician at RE:BERRY Gangnam places a shallow grid across the mapped zone and confirms coverage with a repeat starch-iodine test.

Because the toxin acts only on the nerve endings in the injected skin, it does not affect the sweat glands elsewhere on the body, and normal temperature control through the rest of the skin continues. This local, reversible action is also why the result is temporary: as the treated nerve terminals recover their function over months, the sweat response gradually returns, and a repeat session is planned when the dryness starts to fade.
Questions International Guests Ask About Underarm Botox in Gangnam
How does underarm botox stop excessive sweating?
Sweat glands fire when a nerve releases acetylcholine, the chemical that tells the gland to produce sweat. Botulinum toxin blocks that release at the nerve endings in the treated skin, so the glands under the injected area stop getting the signal and go quiet. The effect is local to the underarm skin that was mapped and injected, and it leaves your body's normal cooling everywhere else untouched. The physician at RE:BERRY Gangnam grids the whole active zone so no overactive patch is left out.
What is the starch-iodine test, and why do you do it first?
It is a simple map of where you actually sweat. The physician paints an iodine solution across each armpit and dusts it with starch, and the powder turns deep blue-black wherever sweat appears. That draws your overactive zone in real time, so the injections cover the skin that genuinely overproduces and skip the quiet areas. No two underarms sweat in the same pattern, and mapping first is what makes the coverage precise. The map is photographed and repeated at follow-up to confirm nothing was missed.
How soon does the sweating actually stop?
It builds over about two weeks. Many guests notice sweating already dropping by roughly forty to fifty percent within the first week, and the full effect settles by around day fourteen. If you are traveling for a specific date, such as an event or the start of your hot season, plan the visit at least two weeks ahead so the dryness has reached its peak by the time you need it.
How long does underarm botox last?
A single session generally holds four to seven months of dryness. After that the treated nerve endings gradually recover, the sweat signal returns, and perspiration slowly creeps back. Most guests schedule a repeat when they feel the sweating beginning again, which many plan ahead of each hot season. The physician sets your interval from how long the effect actually lasts for you, since recovery speed is individual.
Does the injection hurt?
Most guests describe brief pinpricks, closer to a series of small stings than real pain. A numbing cream is left on the skin after the starch-iodine map is drawn, and the needle used is very fine and placed just under the surface. The points are shallow and quick, and the whole grid is finished in a short visit. There is nothing to bandage afterward, and any tenderness is minor and passes within hours.
When is the best time to come, given the Seoul summer?
Since dryness takes about two weeks to reach full effect, booking a few weeks ahead of the hottest stretch means the treatment is working when the humidity peaks. Many Spanish-speaking guests plan the visit in spring, either ahead of the Seoul summer or before flying home to their own hot season, so they walk out dry and stay that way through the heat. The physician plans the timing against your calendar at consultation.
Will it affect the rest of my body or my normal sweating?
No. The toxin acts only on the nerve endings in the underarm skin that was injected, so sweat glands elsewhere on your body are unaffected and continue to regulate your temperature normally. Some people worry the body will sweat much more elsewhere to compensate; in practice any such change is usually minor. The treatment is deliberately confined to the mapped armpit skin and nowhere else.
Is there any downtime, and can I fly home the same day?
There is no downtime that affects a trip. Any faint redness at the injection points fades within a few hours, there is no wound, and a same-day flight is fine. For the first day the physician suggests skipping antiperspirant and intense exercise, and holding off laser hair removal on the area for a couple of days. Beyond those light steps, you return to normal life right away.
How many injections will I need per underarm?
The physician places a spaced grid of shallow points across the blue zone your starch-iodine map reveals, so the number follows the size of your active area rather than a fixed count. The points sit close enough that the whole overactive skin is covered evenly. Because the map is drawn from your own sweating, the grid is planned per side, since the two underarms rarely overproduce in exactly the same pattern.
Can you treat sweaty hands or feet at the same time?
Sweating of the palms or soles can also be assessed, though it is planned separately from the underarms because the technique and comfort measures differ. If you have more than one area that sweats heavily, mention it when you book so the physician can map each region at consultation and set a combined plan. The starch-iodine test can be used on those areas too to confirm where the sweating concentrates.
What is the aftercare once I fly home?
It is light. For the first day avoid antiperspirant and heavy exercise, keep laser hair removal off the area for a couple of days, and do not vigorously rub or heat the underarms right after. Dryness begins within the first week and reaches full effect by around two weeks, so the change unfolds quietly at home. Spanish-speaking coordinators stay reachable on WhatsApp to answer questions through the settling period.
How do I book underarm botox as a foreign visitor from Spain or Latin America?
Message RE:BERRY on WhatsApp with how the sweating affects you and your travel dates, and a Spanish-speaking coordinator replies within a few hours to reserve a physician slot. The clinic is reservation-only for international guests, and staff interpreters cover eight languages including Spanish. The starch-iodine map, the plan, and the injections fit into a single visit, and follow-up continues on WhatsApp after you fly home.
Where is the clinic, and how do I reach it from Gangnam Station?
RE:BERRY sits inside KI Tower on Gangnam-daero, a two-minute walk from Gangnam Station Exit 10 on Seoul Metro Line 2. From Incheon Airport it is roughly forty-five to sixty minutes by AREX plus subway or by direct taxi. Being steps from the station means an underarm botox visit slots cleanly between the rest of a Gangnam itinerary, so you can map, treat, and be back out shopping the same afternoon.

Science Underarm botox for hyperhidrosis: peer-reviewed references
Treating excessive underarm sweating with botulinum toxin rests on a direct evidence base. Naumann (2001) reported a randomized, placebo-controlled trial in bilateral primary axillary hyperhidrosis showing a marked, sustained reduction in sweat production, establishing the treatment as a targeted answer to the condition. The wider efficacy and safety of botulinum toxin type A as an injectable were mapped in large randomized controlled work (Carruthers 2002), and the intradermal, shallow-grid technique used across the underarm has its own supporting record for calming overactive skin glands (Rose 2013). Together these inform how the physician grids the mapped zone and confirms coverage with a repeat starch-iodine test.
