Hyperhidrosis Treatment in Seoul: Botox to Stop Excessive Underarm, Hand and Foot Sweating
Excessive sweating that soaks clothes or makes hands slippery is a medical condition, not a hygiene problem. Botulinum toxin injections block sweat signals for around 4–6 months, with no downtime.

What is the most effective treatment for excessive sweating?
For underarm, hand and foot hyperhidrosis, botulinum toxin injections are among the most effective treatments, reducing sweating by about 80–90% for around 4–6 months. Clinical‑strength antiperspirants and oral medication are other options depending on severity.
Areas we treat
Where excessive sweating occurs
Primary hyperhidrosis usually affects specific areas.
Underarms
The most common area; staining and odour concerns.
Palms
Slippery hands affecting work, writing and handshakes.
Soles
Sweaty feet, slipping in shoes and fungal infection risk; see toe fungus.
Face and scalp
Forehead and hairline sweating.
Body Botox
The same technique used for facial Botox, applied to sweat glands.
Secondary causes
Sweating all over or at night may need medical tests.
How it works
How Botox stops sweating
Sweat glands are activated by a nerve signal (acetylcholine). Small injections of botulinum toxin into the skin block this signal, so the treated area stops producing excess sweat until the nerve endings recover.
- Day 0: starch‑iodine test maps the sweating area
- Days 2–7: sweating reduces
- Week 2: full effect
- Months 4–6: repeat treatment as needed
