Botox for Hyperhidrosis: FDA-Approved Treatment for Excessive Underarm Sweating in Korea

Excessive underarm sweating, also known as axillary hyperhidrosis, can be more than just an inconvenience—it can interfere with daily life, relationships, and self-confidence. If antiperspirants and topical solutions have failed, many people turn to Botox, an FDA-approved treatment for axillary hyperhidrosis, to restore comfort and control.

In South Korea, a country renowned for its excellence in dermatologic and cosmetic treatments, Botox injections for underarm sweating are a trusted, non-surgical option for both local patients and international medical tourists. This article explores the science, safety, and treatment experience of Botox for hyperhidrosis in Korean clinics.


What Is Axillary Hyperhidrosis?

Axillary hyperhidrosis refers to abnormally excessive sweating of the underarms, not necessarily related to physical activity or temperature. It is a chronic condition often caused by overactive eccrine sweat glands, triggered by the nervous system.

Common symptoms include:

  • Persistent wetness in the underarm area
  • Frequent clothing stains
  • Odor due to bacterial growth
  • Social anxiety or embarrassment
  • Impact on personal and professional life

If standard antiperspirants or oral medications are not effective, Botox is one of the most reliable next steps.


What Is Botox for Hyperhidrosis?

Botox (botulinum toxin type A) is a purified neurotoxin that blocks the nerve signals that stimulate sweat production. When injected directly into the underarm area, it temporarily stops excessive sweating by disabling overactive sweat glands.

Key facts:

  • FDA-approved since 2004 for treating axillary hyperhidrosis
  • Localized effect — only the treated area is affected
  • Temporary results, lasting 4 to 8 months on average
  • Safe, non-surgical, and minimally invasive

How Korean Clinics Perform Botox for Underarm Sweating

Korean dermatology and aesthetic clinics are known for their cutting-edge techniques, precision, and international patient services. The Botox procedure for hyperhidrosis is carefully planned to ensure maximum comfort and effectiveness.

1. Consultation

  • Conducted by a board-certified dermatologist
  • Review of medical history and symptom severity
  • Discussion of prior treatments (e.g., aluminum chloride antiperspirants, oral meds)

2. Mapping the Sweat Zone

Some clinics use the Minor’s iodine-starch test, which highlights areas of most intense sweating by turning sweat spots dark blue/purple. This ensures accurate targeting of sweat glands.

3. Botox Injection Procedure

  • Topical numbing cream applied 20–30 minutes prior
  • 10–20 small injections per underarm using ultra-fine needles
  • Entire session completed in 15–30 minutes
  • Minimal discomfort; no general anesthesia required
  • No downtime — patients can resume daily activities immediately

Safety and Side Effects

Botox is generally very safe, especially when administered by licensed Korean dermatologists using medical-grade botulinum toxin. However, mild and temporary side effects may occur:

  • Mild tenderness or bruising at injection sites
  • Localized redness or swelling
  • Temporary compensatory sweating in other areas (rare)
  • Allergic reaction (very rare)

Korean clinics follow global safety protocols and use approved brands such as:

  • Botox® (Allergan)
  • Nabota® (Daewoong Pharmaceutical)
  • Xeomin® (Merz)
  • Dysport® (Ipsen)

Botox is suitable for individuals who:

  • Suffer from moderate to severe axillary hyperhidrosis
  • Have tried and failed with topical or oral therapies
  • Are not pregnant or breastfeeding
  • Do not have neuromuscular conditions (e.g., myasthenia gravis)
