Sweat Reduction Treatment in Seoul: Hyperhidrosis Control
The short answer
Sweat reduction treatment in Seoul most often uses botulinum toxin injections to block the nerve signals that switch on sweat glands in the underarms, palms or feet. Underarm treatment typically costs ₩200,000–₩700,000, takes about 20 minutes and has no downtime. Sweating drops noticeably within two to seven days, and the effect usually lasts four to nine months.

What hyperhidrosis is
Hyperhidrosis means sweating far more than the body needs for temperature control. It often affects the underarms, palms, soles or face and can start in adolescence. It is common and treatable, but many people live with it for years because they assume nothing can be done.
In Seoul, sweat reduction is a routine dermatology treatment, and many patients book it before summer or before a big event.
Botox for sweating
Botulinum toxin is injected in small amounts just under the skin across the sweaty area. It blocks the chemical signal that tells sweat glands to activate. The glands remain, but they produce much less sweat.
- Underarms: the most common and comfortable area
- Palms and soles: effective but more sensitive; nerve blocks or numbing help
- Scalp and forehead: useful for people who sweat heavily from the head
Dryness starts within two to seven days and usually lasts four to nine months, sometimes longer in the underarms. Our hyperhidrosis injection page goes into dosing and areas in more detail.
miraDry and other longer-term options
Microwave devices such as miraDry heat and destroy underarm sweat glands, giving a long-lasting reduction after one or two sessions. They involve local anaesthesia and several days of swelling and tenderness. Some patients also choose them because they reduce odour.

| Feature | Botox | miraDry |
|---|---|---|
| Areas | Underarms, palms, feet, scalp | Underarms only |
| Downtime | None | Several days of swelling |
| Results last | 4–9 months | Long-term |
| Sessions | Repeat 1–2 times a year | 1–2 in total |
What the procedure is like
The doctor may first do a starch-iodine test to map the most active area. After numbing cream or ice, many tiny injections are placed in a grid. Underarms take about 15 minutes. Palms take longer and are more uncomfortable, so clinics may use nerve blocks or vibration.
Side effects
- Small bumps and tenderness at injection points for a day
- Mild bruising
- For palms, temporary weakness in grip is possible
- Compensatory sweating elsewhere is uncommon with Botox
Planning as a visitor
Botox for sweating has no downtime and no flight restrictions. Because dryness takes a few days to appear, book it early in your trip if you want to enjoy the result during your stay. Skip deodorant on the day and wear a loose top. miraDry needs a few days of comfort care, so leave time before flying.

Patient questions
Frequently asked questions
How long does underarm Botox for sweating last?
Usually four to nine months, sometimes longer with repeat treatments.
Is it safe to stop sweating in the underarms?
Yes. Underarms are a small part of the body's sweat output, and temperature control is not affected.
Does hand Botox hurt?
It is more uncomfortable than underarms. Clinics use numbing, vibration or nerve blocks to help.
Can I use deodorant afterwards?
Wait about 24 hours, then resume normal use.
