Summer is approaching – does underarm odour and sweat make even raising your arm feel awkward? Korean axillary osmidrosis (underarm odour) treatment has become highly advanced, but with so many options – microwave (MiraDry), laser (Nd:YAG), and minimally invasive surgery – which one is right for you? Today, we’ll break it down clearly with a single comparison table.
| Comparison | Microwave Thermolysis (MiraDry) | Laser (Nd:YAG / Fiber) | Minimally Invasive Surgery (Curettage / Excision) |
|---|---|---|---|
| Principle | Microwave energy precisely heats and coagulates apocrine glands, causing necrosis | Fiber laser thermally coagulates glands while shrinking pores | Small incision (~1cm) to scrape or excise apocrine glands |
| Suitable candidates | Moderate‑to‑severe odour/hyperhidrosis, no scars, quick recovery desired | Mild‑to‑moderate odour, also wanting hair reduction (laser can remove hair) | Severe, stubborn odour, seeking most thorough elimination |
| Scarring | None (only epidermal heating, no incision) | None (fiber puncture points only) | About 1cm scar, hidden in axillary fold |
| Pain level | Moderate (needs local anaesthesia + cooling protection) | Mild (basically painless under local anaesthesia) | Moderate (pain controllable post‑op) |
| Downtime | 1‑3 days swelling, full recovery in 1 week | 2‑3 days redness, basic recovery in 1 week | Sutures removed in 1 week, avoid arm raising for 2 weeks |
| Longevity | Permanent (glands destroyed, do not regenerate) | Relatively long‑lasting (may need multiple sessions) | Permanent (most thorough removal) |
| Reference price (KRW) | 2,000,000 – 4,000,000 (both sides) | 1,500,000 – 3,000,000 (both sides) | 3,000,000 – 6,000,000 (both sides) |
Summary in one sentence:
• Want non‑invasive, scarless, fast recovery → Microwave (MiraDry) (most popular, but pricier)
• Want hair removal too, mild‑to‑moderate odour → Laser
• Very severe odour, want the most thorough solution → Minimally invasive surgery
This is a non‑invasive treatment approved by the US FDA and Korea’s KFDA. The device precisely delivers microwave energy to the gland‑rich layer (junction of dermis and fat) while a cooling system protects the epidermis. A single session reduces about 80% of sweat glands, and the effect is permanent. The downside is the higher cost, and some people may need a second session for extremely stubborn glands. Korean dermatologists commonly use a marking technique to localise high‑density gland areas, ensuring full energy coverage.
A fiber optic is inserted subcutaneously to thermally destroy glands. It is minimally invasive, with quick recovery from needle punctures, and also damages hair follicles for added hair reduction. However, laser penetration depth is limited, making it less effective on deep apocrine glands compared to microwave or surgery; 2‑3 sessions may be needed for optimal results. It is suitable for mild‑to‑moderate odour and those wanting a “two‑in‑one” benefit.
The traditional method uses a 2‑3cm incision to flip the skin and excise glands. In Korea, a 1cm small‑incision curettage is now common, using a specialised curette to scrape out glands. Its advantage is the most thorough removal, with a low recurrence rate (<5%). The downsides are post‑op bandaging, a longer recovery, and mild scarring. It is best for severe odour or cases where previous treatments have failed.
All prices below are 2026 reference prices from certified dermatology clinics/hospitals in Gangnam, Seoul, in KRW:
| Treatment | Reference Price (KRW) |
|---|---|
| MiraDry (both sides, single session) | 2,000,000 – 4,000,000 |
| Laser for axillary osmidrosis (both sides, single session) | 1,500,000 – 3,000,000 |
| Minimally invasive curettage (both sides) | 3,000,000 – 6,000,000 |
| MiraDry second boost session | 1,500,000 – 2,500,000 |
| Post‑op repair / Botox auxiliary antiperspirant | 500,000 – 1,000,000 |
⚠️ Note: Korean axillary osmidrosis treatment prices vary by hospital grade, physician experience, and whether it’s a first‑time treatment. Director‑level procedures usually add 30‑50% but offer better energy control and safety. Above prices do not include pre‑op tests (e.g., iodine‑starch test) or post‑op care.
| Stage | MiraDry | Laser | Minimally Invasive Surgery |
|---|---|---|---|
| Days 1‑2 | Swelling, mild burning sensation | Mild redness, crusting at puncture points | Dressing and possibly drainage tube |
| Days 3‑7 | Swelling subsides, can shower (avoid hot water) | Almost recovered, can resume normal activities | Sutures removed (day 7), avoid arm raising |
| Week 2 | Full recovery, initial effect visible | Effect starts to show | Light activities allowed, still avoid heavy lifting |
| 1 month | Final effect stabilised | May need a review (if insufficient) | 90% recovered, scars soften |
Most Korean clinics perform these as outpatient procedures. After MiraDry or laser, you can resume daily life immediately; surgery requires 2‑3 days of rest.
Always request an iodine‑starch test during consultation to map the gland distribution so the doctor can treat precisely. Also ask to see “3‑month post‑op tracking” cases.
Final sincere advice: Getting rid of underarm odour isn’t just for others – it’s for your own confidence and freshness. Don’t let odour bother you anymore. Choose the right solution, invest once, and benefit for life. Wear sleeveless tops with ease this summer, and move freely without worry.
