Palmar botox uses botulinum toxin type A injected into the skin of the palm; sweat relief lasts about 4 to 6 months, and a mild, temporary reduction in grip strength is possible but uncommon when injected precisely.
Palm hyperhidrosis treatment with botulinum toxin type A is generally safe in Korea when a qualified doctor screens you, doses correctly and injects intradermally with precision. Sweat relief lasts about 4 to 6 months and is fully reversible. The main palm-specific risk is a mild, temporary weakening of grip, which is uncommon with careful technique.

Palmar hyperhidrosis treatment injects small amounts of botulinum toxin type A into the skin of the palm to block the nerve signal that drives the sweat glands. Because the toxin acts locally where it is placed and wears off over about 4 to 6 months, the effect is inherently temporary and reversible rather than permanent. Randomized studies show it markedly reduces palm sweating while leaving overall hand function intact, which is why it is a well-established option for severe cases that do not respond to antiperspirants.
The palm carries one specific consideration the face does not: the small muscles that control finger movement sit close to the injection field. If the toxin spreads to these muscles, a mild, short-lived reduction in grip or pinch strength can occur, and this is the main palm-specific side effect. Injecting the correct dose into the dermis with an even, gridded pattern keeps the toxin where it belongs and makes this uncommon; controlled trials have reported palm treatment without a meaningful loss of grip when technique is careful.
Reberry Clinic is a dermatology clinic that performs injectables through the clinic’s doctors, using genuine product and a careful assessment of your medical history and hand use. The clinic serves international patients across three Seoul-area locations (Gangnam, Myeongdong, Incheon Airport) with English-speaking support, so you can discuss the grip consideration, suitability and aftercare clearly before any botox treatment for sweaty palms.
Sweating is switched on when a nerve releases acetylcholine onto a sweat gland. Botulinum toxin type A temporarily blocks that chemical messenger, so the treated sweat glands quieten within 2 to 7 days and the palm stays dry. Nothing is removed and the glands are not destroyed; the nerve endings regenerate over roughly 4 to 6 months and sweating gradually returns, which is why the treatment is repeatable and reversible by design.
The palm needs many shallow injections spread evenly across the surface, often 30 to 50 points, because sweat glands are dense there. Placement in the dermis, rather than deep toward muscle, is the key safety factor for keeping grip normal. Korea has a high volume of injector experience, but volume alone is not safety; a genuine toxin at a standard dilution plus an accurate injection map are what matter. Because palm treatment can be tender, the clinic will discuss comfort options such as topical numbing or a nerve block and explain when a different approach, like injection treatment planning, best fits your needs.

The doctor reviews your history and hand use, and rules out contraindications during 1 detailed consultation before any injection.
A genuine botulinum toxin type A is reconstituted at a standard dilution so each of the many small doses behaves predictably.
Injection points are mapped across the palm, commonly 30 to 50 shallow intradermal points, to cover sweat glands while sparing the finger muscles.
Because the palm is sensitive, topical numbing, cooling or a nerve block is offered so the roughly 15 to 20 minute session stays tolerable.
You receive written aftercare and a follow-up around 2 weeks to confirm dryness and check hand function, adding small touch-ups if needed.
See representative outcomes from Reberry Clinic. Results build gradually and vary by individual; your plan is assessed at consultation.
An English-language consultation screens your medical history and confirms you are a suitable candidate before any injection into the palm.
After cleansing, numbing and mapping, the doctor places the intradermal points; a palm session commonly takes around 15 to 20 minutes per hand.
Treatment fits a short Seoul trip; you are asked to keep the hands clean and avoid heavy gripping for a few hours afterward.
Dryness begins in 2 to 7 days and reaches its full effect by about 2 weeks, when it is reviewed.
The effect fades over roughly 4 to 6 months and is fully reversible; a repeat session maintains dryness when you wish.
Palm hyperhidrosis treatment with botulinum toxin type A is generally safe in Korea when a qualified doctor screens you, doses correctly and injects into the skin with precision. The effect lasts about 4 to 6 months and is reversible. Safety depends on the clinic and technique, which is why an honest botox treatment consultation matters.
A mild, temporary reduction in grip is the main palm-specific side effect, and it is uncommon when the toxin is placed evenly in the skin rather than deep toward muscle. Randomized studies found grip strength unchanged with careful technique. This risk is reviewed during your consultation before any injection is planned.
Most side effects are mild and short-lived: brief tenderness, small bruises at injection points, and occasionally a temporary change in grip. These usually settle within days and are checked at your follow-up. Serious events are uncommon and are most often linked to incorrect dosing or non-genuine product.
Palm dryness typically lasts about 4 to 6 months, then sweating gradually returns as the nerve endings regenerate. The effect is reversible by design, so nothing is permanently altered. Many patients schedule a repeat session once dryness begins to fade, which is discussed during your botox treatment review.
The palm is sensitive and needs many small injections, so comfort planning matters; topical numbing, cooling or a nerve block keeps the roughly 15 to 20 minute session tolerable. Most patients describe brief stinging rather than lasting pain. Your comfort options are agreed beforehand during your consultation.
A palm usually needs about 30 to 50 shallow intradermal points because sweat glands are densely packed there. Spreading the dose evenly covers the sweat glands while sparing finger muscles. The exact map is tailored to your hand size and sweat pattern during your assessment before treatment.
Ask the clinic which botulinum toxin type A it uses and confirm a doctor reconstitutes it at a standard dilution. Genuine, properly stored product behaves predictably, which is central to safety. Reberry Clinic uses genuine product and explains your options during the injection treatment consultation so you know exactly what is injected.
For about 24 hours, keep the hands clean, avoid heavy gripping, hot water, saunas and vigorous exercise, which helps the toxin settle where intended. These simple steps lower the small chance of spread toward finger muscles. You receive a written aftercare plan covering exactly what to do.
Yes, first-timers are common candidates; a measured starting dose lets the doctor see how your palms respond and fine-tune at the 2-week review. Starting conservatively is itself a safety measure, since dryness builds over 2 to 7 days. Suitability is confirmed during screening before any injection into the palm.
Treatment is deferred or avoided in pregnancy and breastfeeding, with certain neuromuscular disorders, active infection or broken skin on the palms, or a known allergy to the toxin. Some medications warrant caution too. These are checked during the medical screening that precedes any botox treatment.
Each has a different safety profile: palm botox wears off over months, prescription antiperspirants need constant use, and iontophoresis needs repeated sessions. The key safety factor differs too. Discuss injection treatment options with the team to choose the safest fit for your lifestyle.
Yes, because botulinum toxin acts on sweat nerves beneath the skin rather than on pigment, it does not carry the pigment-related risks of some light-based treatments. Dose and injection map are tailored to your hand by the clinic’s doctors. Your suitability is confirmed during the assessment before any plan is finalized.
There is no instant reversal agent, but the effect is temporary and resolves on its own over about 4 to 6 months as sweating returns. A conservative initial dose lowers the chance of an unwanted grip change, and small adjustments can be made at the follow-up review rather than waiting for it to fully fade.
Yes, Reberry Clinic serves international patients with English-speaking support across three Seoul-area locations, including one near Incheon Airport, so screening, consent and aftercare are explained clearly in English. You can be assessed and treated on your trip. Message us on WhatsApp to discuss suitability and plan your visit.
Because treatment is a single quick session, even a short stop works; the palm injections take about 15 to 20 minutes per hand after screening. There is no required multi-day course, though dryness develops over your first 2 weeks. Our team schedules it around your itinerary and explains remote follow-up.
Yes, most patients fly the same or next day, since skin downtime is minimal and any small marks settle quickly, while dryness develops gradually after you return. You are simply advised to avoid heavy gripping early on, and you receive written aftercare so you can follow up on your botox treatment from abroad.
