Too afraid to raise your arm in summer, always wanting to avoid crowds after exercise – the embarrassment of underarm odour is something only those who have experienced it truly understand. If you’ve already tried deodorants, body sprays, and even folk remedies, but they only provide temporary relief, surgery may be the option you seriously consider. But the word “surgery” naturally raises concerns: does it hurt? How much does it cost? How long is recovery? Will it leave scars? What about recurrence?
Don’t worry – this article doesn’t use jargon or overpromise. It simply lays out the five most critical aspects – effectiveness, cost, recovery process, scarring, and recurrence risk – in clear, digestible detail. All prices are actual 2026 reference prices from Seoul Gangnam (in KRW only, no conversions), to help you get a realistic picture and make a confident decision.
The core mechanism of axillary osmidrosis (underarm odour) surgery is to remove or destroy the apocrine glands that produce the odour. The root cause is the breakdown of organic secretions from the apocrine glands by skin bacteria, producing sulfur‑containing and other malodorous substances. Korean surgeons commonly use subdermal excision or liposuction to precisely remove the subcutaneous tissue containing apocrine glands. In recent years, Korea has also developed newer techniques such as LSG ultra‑minimally invasive sweat gland ablation, which uses endoscopy for visualisation and removes the glands through rice‑sized incisions. Additionally, MiraDry microwave technology offers a non‑invasive option, using microwave thermal energy to permanently destroy sweat glands while cooling the epidermis. Regardless of the method, the goal is to cut off the chain of odour production at its source.
If you have the following characteristics, Korean axillary osmidrosis surgery may be worth considering:
Contraindications include: severe bleeding disorders, poorly controlled diabetes, acute skin infection in the armpit, menstruation/pregnancy/breastfeeding, allergy to anaesthetics, and unrealistic psychological expectations.
Korean axillary osmidrosis surgery mainly offers four options. The doctor will recommend the most suitable one based on your severity, budget, and recovery time needs. Reference prices (KRW only) at mainstream Gangnam clinics in 2026 are as follows:
| Treatment Method | Technical Features | Recovery Time | Longevity | Reference Price (KRW) |
|---|---|---|---|---|
| Conventional Excision | Incision along the axillary skin fold (2‑3cm), direct visualisation and removal of apocrine glands – most thorough. | 2‑3 weeks | Permanent (lowest recurrence) | ₩3,000,000 – 5,000,000 |
| Subdermal Excision (Minimally Invasive) | 1‑1.5cm small incision, precise removal with special instruments – less trauma, inconspicuous scar. | 1‑2 weeks | Long‑term (75%‑90% effective) | ₩4,000,000 – 7,000,000 |
| LSG Ultra‑Minimally Invasive Ablation | Rice‑sized incision, endoscopic visualisation, precise ablation of apocrine glands – virtually scarless. | 5‑7 days | Long‑term | ₩5,000,000 – 8,000,000 |
| MiraDry Microwave Thermolysis | Non‑invasive, microwave thermal energy permanently destroys sweat glands, also reduces underarm hair and odour. | 2‑3 days (mild swelling) | Long‑term (1‑2 sessions) | ₩3,500,000 – 5,500,000 |
Conventional excision is most thorough but more invasive; minimally invasive balances effectiveness and recovery; LSG pursues the best cosmetic outcome; MiraDry suits those who want to avoid scalpels. Botulinum toxin injections are also a non‑surgical option, reducing sweat secretion by inhibiting acetylcholine release – each side costs about ₩100,000‑200,000 and lasts 4‑6 months.
At specialised clinics in Gangnam, the standard axillary osmidrosis surgery process is as follows:
Step 1 – Pre‑operative evaluation: The doctor uses an iodine‑starch test to assess the sweating area and severity, marking the surgical zone.
Step 2 – Local anaesthesia: Local infiltration anaesthesia ensures the armpit area is completely pain‑free.
Step 3 – Incision and gland removal: Depending on the chosen method – conventional excision is performed under direct vision; minimally invasive uses special instruments to scrape or aspirate the gland tissue through a small incision.
Step 4 – Haemostasis and suturing: Fine bipolar coagulation is used, then layered suturing with a drain placed to prevent haematoma.
Step 5 – Compression dressing: A compression dressing is applied for about 3 days to promote skin flap adherence and reduce complications.
Operation time varies: minimally invasive ~30‑60 minutes, conventional ~60‑90 minutes. Pain tolerance is good – the procedure is pain‑free throughout.
Duration: Conventional and minimally invasive surgery provide long‑term stability, with most patients achieving permanent improvement. MiraDry results are also lasting; some may need 1‑2 sessions. Minimally invasive surgery has a certain recurrence rate (~10%‑25%), but the degree is usually far milder than before.
Q1: Can axillary osmidrosis surgery completely cure it?
A: Conventional surgery can achieve near‑complete elimination with a very low recurrence rate. Minimally invasive surgery provides significant improvement (75%‑90% effective), but some recurrence is possible. Discuss with your doctor to choose the most suitable method for your situation.
Q2: How soon can I return to normal work and life after surgery?
A: Sutures are removed in 5‑7 days for minimally invasive procedures, and daily activities can resume in about 2 weeks. Avoid raising arms high, abduction, and strenuous exercise for 2 weeks post‑op.
Q3: How much does axillary osmidrosis surgery cost in Korea?
A: 2026 Gangnam reference prices: conventional ~₩3,000,000‑5,000,000; minimally invasive ~₩4,000,000‑7,000,000; LSG ~₩5,000,000‑8,000,000; MiraDry ~₩3,500,000‑5,500,000. Botox injections per side ~₩100,000‑200,000. Actual costs vary by hospital, surgeon, and scope.
Q4: Will there be obvious scars after surgery?
A: Conventional incisions are ~2‑3cm, relatively visible but hidden in the armpit fold. Minimally invasive incisions are only 1‑1.5cm, with minimal scarring. LSG uses rice‑sized incisions and is virtually scarless.
Q5: Which hospitals in Korea are specialised in axillary osmidrosis surgery?
A: Many Gangnam clinics have specialised departments, such as Apgujeong MK Plastic Surgery, INFINI Plastic Surgery, K’s Plastic Surgery, and Cheongdam ES Plastic Surgery. Choose a clinic with KFDA‑certified equipment and a surgeon with extensive experience in odour surgery.
Axillary osmidrosis surgery is routine, but you should still be aware of potential side effects:
To minimise risks, always choose a certified medical institution and ensure the surgeon has extensive experience in axillary odour surgery. Communicate your expectations clearly before surgery, and strictly follow post‑op care instructions – keep the wound clean and dry, avoid excessive arm movement for 2 weeks, and maintain a light diet (avoid spicy and irritating foods). Approach the outcome rationally – surgery can significantly improve odour but cannot guarantee 100% elimination (especially with minimally invasive methods). Make a reasonable decision based on your own condition.
