Palmar botox involves 30 to 50 precise intradermal points per palm, so how a clinic maps injections and manages a numbing nerve block matters more than any single claim.
To choose a good palm hyperhidrosis clinic near Incheon Airport, look for doctors who assess your sweating with the Minor’s iodine-starch test, use a structured grid of botulinum toxin points across each palm, manage pain with a nerve block or topical numbing, and review grip strength. At our Incheon Airport (Yeongjongdo) location, Dr. Sunbeen Kim leads this consultation-based approach.

Palm hyperhidrosis, or excessive sweating of the hands, is a genuinely disruptive condition, and choosing the right clinic matters because the treatment is technique-dependent rather than device-dependent. Botulinum toxin for sweaty palms works by temporarily blocking the nerve signals that trigger the sweat glands, but the palm is densely innervated and sensitive, so a good clinic plans the injection map carefully rather than injecting at random.
The first sign of a well-run clinic is proper assessment. Doctors should confirm that your sweating is primary (idiopathic) rather than caused by another condition, often using the Minor’s iodine-starch test to visualise the most active areas. From there, the plan is individualised: a typical palm needs roughly 30 to 50 evenly spaced intradermal points so the effect is uniform, not patchy.
Pain management and grip care separate a thoughtful clinic from a rushed one. Palm injections are more uncomfortable than facial botox, so a good clinic offers a wrist nerve block, topical anaesthetic, or vibration and cooling. For international patients, our Incheon Airport (Yeongjongdo) location is convenient for transit and stopover schedules, with English-speaking support and consultation-led care led by Dr. Sunbeen Kim, Medical Director.
Botulinum toxin type A is a neuromodulator that blocks the release of acetylcholine, the chemical messenger the nervous system uses to switch on the eccrine sweat glands. When injected as many small, superficial (intradermal) deposits across the palm, it interrupts these signals locally so the treated area produces far less sweat. Because the palm has a high density of sweat glands over a small surface, a good clinic spaces points roughly 1 to 1.5 cm apart to cover the whole palm and fingers evenly. The effect is not immediate: sweating typically drops within 3 to 7 days as the toxin takes hold, and results commonly last around 4 to 6 months before a repeat session is considered. Crucially, a skilled injector keeps the toxin in the correct superficial plane and avoids the deep muscles that control fine finger movement, which is how modern technique minimises temporary grip or pinch weakness. This is why injection mapping and depth control, not the brand of toxin, are what you should evaluate when comparing clinics.

Doctors confirm primary hyperhidrosis and often use the Minor’s iodine-starch test, since about 90% of visible sweat concentrates in identifiable zones.
The palm and fingers are marked into a grid of roughly 30 to 50 points spaced about 1 to 1.5 cm apart for even coverage.
A good clinic offers a wrist nerve block, topical numbing for 20 to 30 minutes, or cooling and vibration to keep the 15-minute injection tolerable.
Botulinum toxin is placed intradermally, staying superficial to spare the deep muscles, which is how the risk of temporary grip weakness is reduced.
Sweating usually eases within 3 to 7 days and lasts around 4 to 6 months, so the clinic plans your follow-up or next session around that window.
See representative outcomes from Reberry Clinic. Results build gradually and vary by individual; your plan is assessed at consultation.
The clinic’s doctors confirm your diagnosis, map your sweating, and explain the plan and cost factors in English before anything is injected.
After numbing for about 20 to 30 minutes, the injection session across both palms usually takes around 15 to 20 minutes.
Most people can return to normal activities the same day, though light grip tasks may feel slightly different for a day or two.
Sweating typically decreases within 3 to 7 days, with the fuller effect settling over about 2 weeks.
Results commonly last 4 to 6 months, and because this is a chronic tendency, periodic repeat sessions maintain the benefit.
Choose a clinic that confirms your diagnosis, maps sweat zones with the Minor’s iodine-starch test, uses a structured grid of botulinum toxin points, and manages pain properly. Our botox injection care at the Incheon Airport (Yeongjongdo) location is consultation-led by Dr. Sunbeen Kim, Medical Director.
Palm hyperhidrosis treatment uses botulinum toxin injected as many small intradermal points across each palm to block the nerve signals driving the sweat glands. A single session covers roughly 30 to 50 points per palm. It temporarily reduces sweating rather than curing it, so it is repeated periodically to maintain control.
Palm injections are more sensitive than facial ones, but a good clinic manages this well. Options include a wrist nerve block, topical numbing applied for 20 to 30 minutes, or cooling and vibration devices. Most patients describe brief stinging that is very manageable. Ask any clinic exactly how they handle comfort before booking.
Temporary, mild grip or pinch changes are possible but usually minor and short-lived when technique is correct. Skilled injectors keep the toxin superficial in the skin, sparing the deep hand muscles. Studies report significant sweat reduction without meaningful loss of dexterity, which is why injector experience matters more than the toxin itself.
Most people notice drier palms within 3 to 7 days, with the full effect settling by about two weeks. The onset is gradual because the botulinum toxin needs time to interrupt the nerve-to-gland signals. Your doctor reviews the response and can touch up any missed spots if sweating remains uneven.
Results commonly last around 4 to 6 months, and some studies note repeated sessions can extend duration over time. Because hyperhidrosis is a chronic tendency, most patients plan periodic maintenance, which our injection treatment team schedules as the effect naturally wears off.
You typically need one session at a time, repeated when sweating returns, rather than a fixed course. Studies following patients over years describe an average of around four sessions across that period. The exact interval depends on how quickly your sweating comes back, which your doctor tracks between visits to plan follow-up.
Yes, sweaty-palm treatment can be planned alongside other botulinum toxin needs in the same visit where appropriate. Many patients also ask about botox injection for other concerns. Your doctor confirms suitable combinations and total dosing at consultation so nothing overlaps or is over-treated.
Botulinum toxin for palmar hyperhidrosis is widely studied and generally considered safe when performed by a trained doctor at correct doses. Temporary tenderness or mild grip change are the main considerations. A proper consultation screens for contraindications like pregnancy or certain neuromuscular conditions, keeping the procedure appropriate for you.
The most common effects are temporary injection-site tenderness, small bruises, and occasionally brief, mild hand-muscle weakness. These typically settle within days. Serious problems are uncommon with correct technique and dosing. Your doctor explains what to expect and how superficial, intradermal placement is used specifically to protect grip strength.
Botox usually gives longer, more substantial relief per session than prescription antiperspirants, and avoids the frequent repetition of iontophoresis. Antiperspirants suit milder cases, while iontophoresis is a needle-free home option. Your doctor helps you weigh severity, convenience, and cost so the choice fits your lifestyle rather than a one-size approach.
Most adults with moderate to severe primary palm sweating that disrupts daily life are suitable candidates. A consultation first confirms the sweating is primary and screens contraindications. If your sweating stems from another cause, your doctor addresses that first. You can start via our injection treatment page.
Aftercare is simple: avoid heavy hand friction, hot baths, and vigorous gripping for the first day, and skip hand massage over the treated area. Most people resume normal activity immediately. Your doctor may suggest gentle skincare, and you can explore a supportive skin care routine to keep hand skin comfortable.
Palm hyperhidrosis is cared for at our Incheon Airport (Yeongjongdo) location, led by Dr. Sunbeen Kim, Medical Director, which is convenient for transit and stopover patients near ICN. Care is also available at our Seoul locations. You can start via the botox injection page with full English support.
One short visit is usually enough, since the injection session takes about 15 to 20 minutes plus numbing time. Because our Incheon Airport location sits near ICN, many international patients fit treatment around a layover or the start of a trip. A single day is typically sufficient for the procedure itself.
Yes, flying shortly after treatment is generally fine, as the procedure is minimally invasive with no significant downtime. You may feel mild tenderness handling luggage, so pack light for the first day. Being near Incheon Airport makes it easy to travel on the same day if your schedule requires it.
International patients can be reviewed remotely between visits, and the clinic keeps your treatment notes and injection map on file for continuity. When sweating returns after about 4 to 6 months, you can plan a repeat session on a future trip. Our English-speaking team helps coordinate timing around your travel.
