Hyperhidrosis Botox in Busan: Excessive Sweating Treatment
Excessive sweating, or hyperhidrosis, is more common than many people realise, and it can affect everything from what you wear to whether you want to shake hands. Botulinum toxin is a well-established, non-surgical way to reduce it, and because the treatment has no downtime it is easy to fit into a visit to Busan, ideally before a hot, humid Korean summer. This guide explains how hyperhidrosis Botox works, who it suits, what to expect and how pricing works in Seomyeon.
Quick answer: Hyperhidrosis Botox places small doses of botulinum toxin just under the skin of the underarms, palms or soles, where it temporarily blocks the nerve signals that switch sweat glands on. A session takes about 15–20 minutes after 20–30 minutes of numbing cream, you can return to normal activities straight away, sweating starts to drop within 2–4 days and results usually last about 6–9 months. In Seomyeon, pricing depends on the area and dose, so the clinic quotes it on WhatsApp.
What is hyperhidrosis?
Hyperhidrosis means sweating more than the body needs to cool down. The most common form, primary hyperhidrosis, usually starts young, affects both sides equally (both underarms, both palms or both feet) and is not caused by another illness. It can soak through clothes on cool days, make palms slippery when writing or using a phone, and make shoes uncomfortable.
When to get checked first
Sweating that starts suddenly in adulthood, happens mainly at night, affects the whole body, or comes with weight loss or fever is different. These patterns can have an underlying medical cause and should be assessed by a doctor before any cosmetic treatment.
How hyperhidrosis Botox works
Sweat glands are activated by acetylcholine, a chemical messenger released by nerve endings. Botulinum toxin type A temporarily blocks this signal. Unlike wrinkle Botox, which goes into muscle, hyperhidrosis Botox is placed shallowly in a grid of small points across the sweating area, where the glands sit. The glands are not removed or damaged; they simply receive less signal until the nerve endings recover over several months. Using botulinum toxin for underarm sweating is supported by good clinical evidence and is approved for this use in many countries.
Who it suits, and who should choose something else
- Underarm sweat marks your clothes even at rest or on cool days.
- Sweaty palms make handshakes, writing or phone use awkward.
- Sweaty feet make shoes slippery or uncomfortable.
- Strong antiperspirants have not worked well enough, or they irritate your skin.
Other options to consider
- Slimming shoulders or calves rather than reducing sweat: body Botox targets muscle instead.
- Underarm hair is the main concern: laser hair removal may be the better fit.
- Pregnancy, breastfeeding, a neuromuscular disorder or skin infection in the area: treatment should wait.
How much does hyperhidrosis Botox cost in Busan?
In Seomyeon, there is no fixed listed price for sweat Botox. It depends on the area (underarms, palms or soles), the size of the sweating zone and the dose the doctor recommends. Send a WhatsApp message with the areas you want treated and you will get a quote before you travel.
All clinic prices are in won, exclude 10% VAT (checked October 2026) and are paid at the clinic on the day. Prices can change, so confirm before booking. When comparing quotes elsewhere, ask how many units are included per area and which toxin brand is used, since sweat treatment typically uses more toxin than a single wrinkle area.
What happens on the day
- Message ahead. Say which areas sweat most, how long it has been a problem and your travel dates.
- Consultation. The doctor asks when and where you sweat, reviews your health history and confirms the area and dose.
- Numbing. Numbing cream is applied for about 20–30 minutes, and the sweating zone may be mapped on the skin.
- Treatment. Many tiny injections are placed over about 15–20 minutes. Underarms feel like light pinches; palms and soles are more sensitive.
- Back to your day. No downtime.
Results: what to expect and when
- Days 2–4: sweating starts to decrease in the treated area.
- Weeks 1–2: the full effect is usually reached.
- Months 6–9: sweating gradually returns as nerve signals recover.
- Ongoing: repeat treatment maintains the result. Many people time it before summer.
Results on palms and soles can last differently from underarms, and how long it works varies with gland activity and lifestyle.
Side effects and aftercare
Hyperhidrosis Botox is generally well tolerated when performed by a doctor. Possible effects include soreness, redness, small bumps or bruising at injection points. After palm treatment, some people notice temporary mild weakness of grip or finger strength, which is why the dose is placed carefully there. Allergic reactions are rare. Because the toxin acts only where it is placed, it is not expected to cause sweating elsewhere, although some people notice normal sweating in other areas more once the main area is dry.
Aftercare tips
- For 3–4 hours, avoid lying on or rubbing the treated area.
- On the day, skip saunas, jjimjilbang, hot baths, alcohol and strenuous exercise.
- Leave deodorant off the treated area until the next day unless advised otherwise.
- Do not massage the area.
Planning treatment around a trip
You can sightsee and fly as planned. If your palms or soles are treated, they may feel tender for a day, so avoid scheduling a long hiking day or a full day of walking around Busan immediately afterwards. Because full effect takes about two weeks, have it a couple of weeks before a wedding, summer holiday or important event. If you are also having facial Botox on the same trip, tell the doctor so the total dose is planned together.

Frequently asked questions
Does Botox for sweating hurt?
Numbing cream helps. Underarms feel like light pinches; palms and soles are more sensitive.
Is it safe to stop underarm sweating?
Yes. Underarms account for only a small share of your body’s cooling, and the rest of your skin keeps regulating temperature normally.
Does it help with underarm odour?
Many people notice less odour because there is less sweat for bacteria to break down, though this varies.
