What Is Hyperhidrosis and Why Does It Need Medical Treatment?
Hyperhidrosis is a condition characterized by excessive sweating beyond what is needed for thermoregulation — occurring in daily situations without heat or exercise. The most commonly affected areas are the armpits, palms, and soles of the feet. Antiperspirant products offer limited relief. Botulinum toxin injection is internationally recognized as the most effective non-surgical treatment for hyperhidrosis.

How Does Botox Treat Hyperhidrosis?
Botulinum toxin Type A temporarily blocks sympathetic nerve endings that control sweat glands, inhibiting acetylcholine release and dramatically reducing sweat production. Effects begin 5–7 days after injection and reach peak efficacy at 2–4 weeks, lasting 6–12 months.
Hyperhidrosis Treatment Options at Rappoel
① Coretox Botulinum Toxin (First Choice)
Rappoel uses Coretox — a widely trusted Korean botulinum toxin brand — for hyperhidrosis treatment. Approximately 50 units per axilla for underarm hyperhidrosis; dosage for palms and soles is adjusted according to sweat gland density. The procedure takes 30–40 minutes.
② Xeomin (German) & Botox (US)
For patients who have developed tolerance to Korean toxin brands or who have specific preferences, Rappoel also offers German Xeomin and American Botox, ensuring consistent treatment efficacy.
Pre- and Post-Treatment Guidelines
Avoid alcohol-based antiperspirant sprays for 24 hours before treatment. Keep the treatment area clean on the day of the appointment. Inform your doctor if you have keloid tendencies or any specific skin conditions.
Avoid vigorous exercise for 24 hours post-injection. Do not massage the injection area for 4 hours. You can return to normal daily activities immediately. Sweating reduction typically becomes noticeable within 1 week.
Efficacy and Duration
Botulinum toxin treatment for axillary hyperhidrosis achieves a success rate of over 90%, with most patients experiencing an 80%+ reduction in sweating. Effects last 6–12 months, and with regular maintenance, some patients find that the interval between treatments gradually extends over time.
