What Is Botox for Underarm Sweating?
Botox (botulinum toxin) for hyperhidrosis involves injecting small amounts of the neurotoxin into the underarm area to block acetylcholine—the chemical messenger that triggers sweat production. It is one of the most established non-surgical treatments for excessive sweating, and is widely performed at dermatology clinics throughout South Korea.
Rappoel Dermatology Clinic uses KFDA-approved Botox (Coretox / Botox®), administered directly by the clinic director for precise placement and optimal dosage control.
Who Should Consider Botox for Sweating?
- Those who experience heavy underarm sweating during normal daily activities
- Visible sweat stains even without physical exertion
- Over-the-counter antiperspirants and deodorants have not worked
- Avoiding light-colored clothing due to sweat marks
- Accompanying underarm odor concerns
The Rappoel Hyperhidrosis Treatment Process
1. Consultation: The director evaluates sweating severity and rules out underlying medical causes such as thyroid disorders.
2. Iodine-Starch Test: An iodine-starch mapping test is applied to precisely identify active sweat gland areas for targeted injection.
3. Injection: Using ultra-fine needles, approximately 15–20 injections per underarm in a grid pattern. The procedure takes 15–20 minutes.
4. Post-Procedure: A brief observation period, then you’re free to leave. No special rest needed.
How Fast Does It Work and How Long Does It Last?
Sweat reduction typically begins within 3–7 days, with optimal results at 2 weeks. Most patients experience an 80–90% reduction in underarm sweating. Results generally last 6–8 months, with 1–2 annual sessions recommended for maintenance.
Does It Hurt?
Rappoel uses ultra-fine needles, making the sensation similar to a mild insect bite. Most patients tolerate the procedure without anesthesia. For particularly sensitive individuals, numbing cream can be applied beforehand. Mild bruising or redness may occur but resolves within 1–2 days.
