What Is Hyperhidrosis?
Hyperhidrosis is a condition where certain areas of the body—most commonly the underarms, palms, and soles—produce excessive sweat regardless of temperature or stress levels. Underarm hyperhidrosis not only causes visible sweat stains but can also lead to social anxiety and reduced self-confidence.
Botox for hyperhidrosis has been used clinically for over 20 years and is approved by both the US FDA and Korean KFDA as a safe and effective treatment for underarm excessive sweating.
How Does Botox Stop Sweating?
Botox works by blocking the release of acetylcholine, temporarily inhibiting the nerve signals that stimulate sweat glands. Unlike antiperspirants that merely “plug” pores, Botox directly shuts down the sweating command at the neural level.
Rappoel’s Hyperhidrosis Treatment Process
1. Assessment: The director evaluates sweating severity and confirms whether it’s primary hyperhidrosis (ruling out secondary causes like thyroid conditions).
2. Iodine-Starch Test: Iodine and starch are applied to the underarms, with color change precisely mapping the most active sweating zones for accurate injection targeting.
3. Injection: Intradermal injections are administered at approximately 15–20 points per underarm. The procedure takes about 20–30 minutes.
4. Post-Care:Normal activities can be resumed immediately. Avoid intense exercise and high-heat environments for 24 hours.
When Do Results Appear? How Long Do They Last?
- Sweating reduction begins within 2–4 days
- Optimal results at 1–2 weeks
- Average sweating reduction of 80–90%
- Results last 4–9 months (varies by individual)
- Maintenance injections recommended every 6 months
Does It Hurt?
Underarm skin is thin and sensitive. Rappoel applies a topical numbing cream for 20–30 minutes before the procedure, significantly reducing discomfort. Most patients describe the sensation as mild pricking—well within tolerable range.
