Hyperhidrosis Treatment in Seoul (Hongdae): Sweat Botox and More
Hyperhidrosis is excessive sweating beyond what the body needs to cool down, most often in the underarms, hands or feet. Botox injections are a common, quick option that usually reduce sweating for about 4 to 6 months. Other approaches include prescription antiperspirants and iontophoresis. A doctor confirms the cause and best option for you.

How it works
Sweat glands are activated by nerve signals. In primary hyperhidrosis, these signals are overactive, often starting in adolescence and affecting both sides of the body. Sweating can also be secondary to other medical conditions or medications, which a doctor checks first.
Botox blocks the nerve signal that switches on sweat glands in the treated area. Many small injections are placed just under the skin of the underarms, palms or soles. Botox is FDA-approved for severe underarm sweating, and the effect typically lasts around 4 to 6 months.
Other options include high-strength prescription antiperspirants, iontophoresis for hands and feet, and device-based treatments that reduce sweat glands. The doctor explains which options are available and suitable for you at consultation.

Frequently asked questions
How much is sweat Botox in Seoul?
Price depends on the area treated, such as underarms, palms or feet, and the units required. Underarms are usually the most common and quickest. Message us on WhatsApp for current options, and the doctor confirms the quote at consultation. Because every face and skin type is different, the doctor confirms what is suitable for you during your consultation, and results vary from person to person.
Does Botox for sweating hurt?
Underarm injections are generally well tolerated, with quick pinches from a fine needle. Palms and soles are more sensitive, so numbing cream, ice or other comfort measures are used. The procedure usually takes 15 to 30 minutes. If you are visiting Seoul for a short time, tell us your travel dates when you book so the doctor can plan treatment timing around your flight.
How long does it last?
Botox for sweating typically lasts about 4 to 6 months, sometimes longer for underarms. Results vary by person and area. Many people repeat treatment before summer or important events. Our English-speaking team can answer follow-up questions on WhatsApp or KakaoTalk before your visit and after you return home.
Will blocking sweat in one area be harmful?
The treated areas make up a small part of the body's total sweat glands, so normal body temperature control continues through the rest of the skin. Some people notice slightly more sweating elsewhere, but this is uncommon with Botox. The doctor will also review your medical history, current medications and any previous treatments before recommending anything.
Can I fly after treatment?
Yes. There is no downtime, so you can fly the same or next day. Avoid heavy exercise and saunas for 24 hours. Written aftercare instructions in English are provided, and you can message us any time if something does not feel right.
How soon will I notice less sweating?
Most people notice a reduction within a few days, with full effect at about 2 weeks. Treat early in your trip if you want the doctor to review the result before leaving Seoul. Booking early in your trip also leaves time for a quick check with the doctor before you leave Korea, if one is needed.

Struggling with excessive sweating that disrupts your daily life? Hyperhidrosis can be both physically uncomfortable and emotionally distressing. At our clinic in Hongdae, we offer safe and effective treatments to control overactive sweat glands—helping you stay dry, confident, and comfortable throughout your day.
What Is Hyperhidrosis?
Hyperhidrosis is a condition characterized by abnormally excessive sweating, typically beyond what is needed for body temperature regulation. It can affect:
- Underarms (axillary hyperhidrosis)
- Palms (palmar hyperhidrosis)
- Soles of the feet (plantar hyperhidrosis)
- Face, back, or other localized areas
Hyperhidrosis can be primary (without an underlying cause) or secondary (linked to another medical condition).
Why Treat Hyperhidrosis?
Key Benefits:
✅ Drastically reduces excessive sweating
✅ Enhances confidence in social and professional settings
✅ Prevents sweat stains, odor, and skin irritation
✅ Minimally invasive with long-lasting results
✅ Safe for both men and women
✅ Quick procedure with no significant downtime
Hyperhidrosis Treatments Offered
We offer multiple effective treatment options tailored to the severity and area of sweating:
- Botox Injections
FDA-approved for treating excessive underarm, hand, and foot sweating. Temporarily blocks nerve signals to sweat glands, reducing sweat production for 4–6 months. - Iontophoresis Therapy
Uses mild electrical currents to reduce sweating in the hands and feet—ideal for patients avoiding injections. - Topical Prescription Solutions
High-strength antiperspirants or aluminum chloride compounds for mild to moderate cases. - Microwave Thermolysis (e.g., miraDry®)
Permanently destroys sweat glands in the underarms using heat energy—long-term results with just 1–2 sessions. - Radiofrequency (RF) or Laser-Based Sweat Gland Ablation
Targets and disables sweat glands in a precise, non-surgical manner for long-term reduction.
What to Expect During Treatment
- Botox: The procedure takes 15–30 minutes, with minor discomfort from fine needle injections. Results start within 3–7 days.
- Iontophoresis: Each session takes 20–40 minutes, usually done several times a week at first.
- MiraDry or RF: Sessions last 45–60 minutes, with localized numbing. Mild swelling or soreness is expected post-treatment.
Most treatments allow you to return to daily activities immediately.
Who Is a Good Candidate?
You may be a good candidate if:
- You experience frequent or uncontrollable sweating
- You’ve tried topical solutions without success
- Sweating affects your clothing, relationships, or job performance
- You want a safe, non-surgical option with visible results
- You’re in good general health with no contraindications to treatment
Treatments are available for both primary and secondary hyperhidrosis, depending on your medical history.
How Long Do Results Last?

- Iontophoresis: Requires regular maintenance sessions
- miraDry / RF Ablation: Permanent reduction in underarm sweating
