Stay dry
for six months.
No pills, no surgery.
Hyperhidrosis botox is FDA-approved for excessive underarm sweating and also treats palms, soles, and forehead. One 20-minute treatment provides 4–6 months of dryness — life-changing for patients who struggle with social, professional, or physical discomfort from sweating.
At a glance.
A single treatment that delivers half a year of dryness.
Hyperhidrosis botox blocks the nerve signals that activate sweat glands in targeted areas — underarms, palms, soles, or forehead. Sweating reduces by 80–90% within 1 week and stays suppressed for 4–6 months. It's the most effective non-surgical treatment for hyperhidrosis, a medical condition affecting 3% of people globally. JRYN offers 4 brand tiers from ₩40,000 (Korean Standard) to ₩220,000 (Allergan, FDA-approved) per 50 units.
The science
,
simplified.
Understanding the mechanism helps you set realistic expectations and choose the right brand for your goals.
Understanding hyperhidrosis
Eccrine sweat glands (for cooling) are controlled by nerve signals. In hyperhidrosis, these glands over-fire even without heat or exertion. Botox interrupts the nerve-to-gland signal.
Grid injection technique
Dr. Lee marks the sweating area using the Minor iodine-starch test (optional) or anatomical landmarks. Then injects small doses of botox at ~15–25 points spaced 1.5–2cm apart in a grid pattern.
Sweat glands 'turn off'
Within 3–7 days, sweat production in the treated area drops 80–90%. Other body areas compensate slightly (normal and harmless). Effect is localized only.
Duration and maintenance
Effect lasts 4–6 months for underarms. Palms and soles may last slightly shorter (3–5 months) due to higher natural activity. Most patients repeat every 6 months to stay dry year-round.
Where we inject
,
and why.
Each area has its own anatomical target, typical dose, and result timeline. Dr. Lee will recommend a personalized plan during consultation.
| Area | Concern Treated | Typical Dose | Results In |
|---|---|---|---|
| Underarms (Axilla) | Visible sweat stains, odor, social anxiety | 50u per side | 3–7 days |
| Palms | Wet handshakes, slippery grip, damaged electronics | 50u per palm | 5–7 days |
| Soles of Feet | Foot odor, slippery inside shoes | 50u per sole | 5–10 days |
| Forehead | Visible facial sweat, makeup melting | 20–30u | 3–5 days |
