Coretox Axillary Hyperhidrosis Treatment Seoul | Rappoel Clinic Underarm Sweating 2026



Hyperhidrosis Is More Than Just Sweating — It’s a Medical Condition

Axillary hyperhidrosis is a condition where the underarm sweat glands produce far more sweat than the body needs for temperature regulation. Patients sweat heavily regardless of temperature or activity level, causing visible sweat stains, discomfort, and significant social anxiety. Standard antiperspirants are ineffective for most hyperhidrosis patients.

Rappoel Dermatology Clinic in Seoul treats axillary hyperhidrosis with Coretox botulinum toxin, injected into the sweat-dense underarm skin to block the neural signals that activate sweat glands. The result: an 80–90% reduction in underarm sweat output, lasting 6–8 months per treatment.

How Botulinum Toxin Treats Hyperhidrosis

Sweat gland secretion is regulated by acetylcholine nerve signals. When Coretox is injected into the underarm skin, it blocks nerve endings from releasing acetylcholine, effectively disabling the sweat glands in the treated area. Effect begins within 1 week of injection, peaks at 2 weeks, and lasts 6–8 months.

Who Is This Treatment For?

  • Patients with abnormally heavy underarm sweating that regular antiperspirants cannot control
  • Those whose sweating significantly affects work performance, social confidence, or quality of life
  • Patients preferring a non-surgical alternative to sweat gland removal procedures
  • Those needing short-term control for specific occasions (weddings, presentations, etc.)

Procedure at Rappoel

  • Pre-treatment evaluation: assess severity; rule out secondary causes (e.g., thyroid disorders)
  • Optional iodine-starch test to map highest-activity sweat zones for precise targeting
  • Topical anesthesia for 20 minutes
  • Multi-point injection throughout the underarm sweat-dense zone
  • No recovery period; normal activities immediately after treatment

Expected Results

  • Week 2: Peak effect — underarm sweating reduced by 80–90%
  • Month 6–8: Effect gradually diminishes; retreatment to maintain results

Frequently Asked Questions

Is botulinum toxin safe for treating underarm hyperhidrosis?
Yes. Intradermal botulinum toxin injection for axillary hyperhidrosis is a globally recognized, guideline-approved treatment in dermatology with an excellent safety profile and very low adverse event rate.
Is the dose the same as for facial Botox?
No. Hyperhidrosis treatment typically requires a higher total dose than facial injections, but uses intradermal (shallow) injection technique targeting only sweat glands — no muscle effects involved.
Will I still be able to sweat normally after treatment?
Yes. Only the injected underarm area is affected. The rest of your body’s temperature regulation remains fully intact — you will still sweat normally elsewhere.
How long do results last and when should I retreat?
Results typically last 6–8 months. When underarm sweating gradually returns toward pre-treatment levels, a repeat injection is recommended. Most patients manage the condition with 1–2 treatments per year.
What should I do to prepare for the treatment?
Clean the underarm area on the day of treatment; do not apply antiperspirant or deodorant. Inform the physician of any medications you are taking, particularly blood thinners.
