Gangnam Seoul Yaan Clinic Guide
miraDry is one of the few treatments that permanently reduces underarm sweat and odor rather than just managing it. This guide explains how it works, who it suits, and what a realistic recovery and results timeline looks like.
What should I know before booking miraDry in Korea? miraDry uses microwave energy to permanently destroy underarm sweat and odor glands, typically in one to two sessions spaced about three months apart, with one to two weeks of swelling and tenderness as recovery — it’s a permanent reduction, not a temporary management option like antiperspirants or Botox.
What miraDry
Actually Does
miraDry delivers targeted microwave energy to the underarm to permanently destroy the sweat and odor glands located there. Unlike antiperspirants, which block sweat temporarily, or Botox injections, which need to be repeated every several months as the effect wears off, miraDry’s effect on the treated glands doesn’t fade — once a gland is eliminated, it doesn’t regenerate. For a closer look at what our patients say about the overall Yaan Clinic experience with this treatment, see the Miradry Gangnam Yaan Clinic Guide.
Most patients complete treatment in one to two sessions rather than an ongoing course, which sets it apart from most sweat-management options on the market. The tradeoff is a period of swelling and tenderness immediately after treatment, since the energy does cause a genuine tissue response rather than a surface-level effect.
Why “permanent” is an accurate claim here, not marketing language
Sweat and odor glands, once destroyed by the microwave energy, do not regenerate — this is a genuine biological limit, not something that fades like injectable results. The remaining sweat capacity comes only from glands outside the treated zone.
Yaan Clinic consultation standard · candidacy and expectations reviewed before booking
miraDry isn’t the right fit for every underarm. Patients with very little underarm fat tissue may not be ideal candidates, since the treatment depth is calibrated relative to tissue thickness, and a thorough consultation reviews this before booking rather than assuming universal candidacy.
| Option | How long it lasts | What it actually does |
|---|---|---|
| Antiperspirant | Hours to a day | Temporarily blocks sweat ducts at the surface |
| Botox injections | 4–6 months | Temporarily blocks the nerve signal to sweat glands |
| Surgical sweat gland removal | Permanent | Physically excises glands, with a longer recovery and scarring risk |
| miraDry | Permanent | Destroys sweat and odor glands with microwave energy, no incision |
The gap miraDry fills is between the two extremes above: it offers the permanence of surgery without an incision, and without the repeat visits that come with Botox or antiperspirants.
Who miraDry
Actually Suits
Excessive underarm sweating
Patients with hyperhidrosis who’ve struggled with sweat marks despite strong antiperspirants often see a meaningful, lasting reduction after treatment.
Persistent body odor
Since odor glands are treated along with sweat glands, patients whose main concern is odor rather than visible sweating are also good candidates.
Tired of repeat Botox appointments
Patients currently managing sweat with Botox injections every few months often choose miraDry to stop the repeat visits entirely rather than maintaining an ongoing schedule.
Very lean underarm tissue
Patients with minimal underarm fat may need a modified approach or may not be ideal candidates — this is assessed individually rather than assumed from a general description.
The Consultation
and Treatment Process
Candidacy assessment
Underarm tissue thickness, sweating severity, and any prior treatments like Botox are reviewed to confirm miraDry is a good fit and to plan session count.
Numbing
The underarm area is shaved, marked, and numbed with local anesthetic so the treatment itself is comfortable.
Energy delivery
The device is applied across the marked treatment grid, delivering microwave energy to the depth where sweat and odor glands are located, typically taking about an hour per underarm.
Cooling and aftercare
The skin surface is cooled during and after treatment to protect it, and ice packs plus activity guidance are provided for the initial recovery period.
Both underarms are typically treated in the same visit, so there’s no need to plan separate appointments for each side. Patients traveling from outside Korea often schedule the consultation and treatment within the same trip, but should plan to be in the country for at least the first few days of recovery in case the clinic wants to check the area before travel — this is discussed individually rather than assumed, since swelling severity varies by patient.
Results and
What to Expect After
- Day 0–3
Swelling and tenderness peak
The underarm area is typically swollen, tender, and slightly numb during this window — this is expected and part of the normal healing response, not a complication.
- Week 1–2
Swelling resolves
Most swelling and tenderness resolves within one to two weeks, at which point most patients are back to full normal activity including exercise.
- Month 3
Second session, if planned
Patients planning a second session for maximum reduction typically return around this point, once the treated area has fully healed from the first session.
How much reduction to expect depends partly on how severe the sweating was to begin with. Patients with moderate hyperhidrosis often reach a result they’re satisfied with after a single session, while patients with more severe sweating are more likely to be advised toward a second session from the start rather than waiting to see how the first one performs. Either way, the destroyed glands don’t return, so the second session adds further reduction rather than repeating or refreshing the first.

If you’re currently managing sweat with Botox injections, mention your treatment history at booking — it helps the doctor assess how your underarm tissue may respond to miraDry.
miraDry is treated as a standalone procedure at Yaan Clinic rather than bundled into a broader visit, so patients coming in primarily for skin or injectable treatments can add a miraDry consultation to an existing trip without it changing the plan for their other treatments.
Frequently Asked
Questions
- Does miraDry hurt?
- The underarm area is numbed with local anesthetic before treatment, so most patients feel pressure or warmth rather than sharp pain during the session. Some tenderness and swelling is common for the following one to two weeks as the area heals.
- How many sessions do I need?
- Most patients see significant sweat and odor reduction after one session, with a second session about three months later recommended for patients with more severe sweating or who want maximum reduction. This is typically a one-to-two-session treatment, not an ongoing course.
- Is miraDry permanent?
- Yes — the microwave energy permanently destroys the treated sweat and odor glands, which do not regenerate. Some patients may still sweat slightly from glands outside the treated area, but the core reduction in the treated zone is considered permanent.
- What’s the downtime like?
- Swelling, tenderness, and some numbness in the underarm area is common for one to two weeks, with most patients returning to light daily activity within a few days. Strenuous exercise and activities that raise the arms overhead are typically paused for a week or two.
- Who is a good candidate for miraDry?
- Patients with excessive underarm sweating (hyperhidrosis) or persistent body odor who haven’t found lasting relief from antiperspirants or Botox injections are typically good candidates. A consultation confirms candidacy, since underarm tissue thickness and prior treatments can affect the approach.
