What Is MiraDry Fresh?
A Different Approach to Underarm Sweat Treatment

For most people dealing with hyperhidrosis, the options feel circular: antiperspirants stop working, Botox wears off in six months, and surgical gland removal carries risks most aren’t comfortable with. MiraDry Fresh sits outside that loop. It’s an FDA-cleared device that uses microwave energy to destroy underarm sweat and odor glands directly — not block them, not suppress them. Once destroyed, those glands don’t come back.

The device targets eccrine glands (the source of sweat), apocrine glands (which drive underarm odor, or bromhidrosis), and some hair follicles in the same tissue layer. This is why patients seeking bromhidrosis treatment in Korea increasingly choose MiraDry over odor-specific options — it handles both sweat and odor in one session, without surgery.

At Yaan Clinic in Gangnam, the session runs about one hour and includes the treatment itself plus a post-procedure step called LDM Healing Therapy — a local aftercare protocol designed to extend the thermal effect and reduce swelling. More on both below.

Yaan Clinic has been verified by MiraDry Asia Pacific as having the highest genuine tip usage among Korean clinics for 2022, 2023, 2024, and 2025. The distinction is based on procedure volume data, not self-reported figures.

How MiraDry Fresh Works –
Microwave Energy & Permanent Gland Removal

The mechanism is worth understanding before you decide anything.

Underarm sweat comes from eccrine glands. Underarm odor comes from apocrine glands. Both sit at roughly the same depth in the skin — the dermal-fat junction. MiraDry Fresh delivers controlled microwave energy to that exact layer. The glands absorb the heat and are destroyed. At the same time, the device cools the skin surface above to prevent damage. The result, across clinical studies, is an average sweat reduction of around 82%.

One question that comes up often: does removing these glands affect anything else? The short answer is no. Underarm glands account for less than 2% of the body’s total sweat output. Thermoregulation — your body’s ability to manage heat — is not affected. This applies to patients with hyperhidrosis in Korea and elsewhere; the physiology is the same.

One Hour MiraDry Fresh –
4-Step Process at Yaan Clinic

The session at Yaan Clinic runs roughly one hour. Patients stay in the same private room throughout — no moving between areas. Male and female physicians are both available; you choose before the session begins. Here’s what happens in order.

Recovery After MiraDry Fresh –
Day-by-Day Timeline

Recovery is shorter than most patients expect going in. Swelling happens — that’s normal — but it resolves faster than surgical alternatives, and most people manage it without taking time off work. The breakdown below reflects what patients at Yaan Clinic typically experience.

Why Yaan Clinic –
What the Numbers Actually Show

Most clinics performing MiraDry in Korea offer it as one of many treatments. At Yaan Clinic, it’s a primary focus — and the procedure volume reflects that. A few specifics worth knowing before you book anywhere in Gangnam or Seoul.

• Volume Data, Externally Verified

  Since 2019, Yaan Clinic has performed over 1,900 MiraDry Fresh cases. For four consecutive years (2022–2025), MiraDry Asia Pacific’s own tip consumption data has placed Yaan Clinic at the top among Korean providers — a ranking the regional executive team confirmed by visiting in person. That’s the one number worth knowing before you compare clinics.

• Focus, Not Breadth

  MiraDry Fresh is a primary focus at Yaan Clinic, not a side offering. The team includes dedicated male and female physicians for the procedure, and the protocol — mapping, anesthesia, treatment, LDM aftercare — is consistent across cases rather than improvised per patient. For patients coming from outside Korea specifically for underarm sweat treatment, this consistency matters.

• Treatment Certificate · 2023 Machine · Academic Exchange

  Yaan Clinic issues a written certificate after each session documenting shot count and energy delivered — useful if you’re comparing clinics or want a record of exactly what was done. The device was replaced with the 2023 MiraDry Fresh model. The clinical team has also done direct exchanges with MiraDry specialists in Japan (SBC network) and Singapore (Dr. Calvin Chan).

Frequently Asked
Questions

Does MiraDry Fresh permanently remove sweat glands?

Yes — the glands are destroyed, not suppressed. Sweat glands don’t regenerate after microwave treatment, so the reduction holds. Clinical data puts the average at around 82% sweat reduction, though individual results vary depending on gland density. Some patients come back for a second session; most don’t need one.

Is MiraDry Fresh safe? What are the side effects?

The device is FDA-cleared, which matters for something this specific. Side effects are mostly what you’d expect from any localized heat treatment: swelling, bruising, temporary numbness. These usually settle within a week or two. The one concern people raise most — “won’t I sweat somewhere else?” — doesn’t hold up medically. Underarm glands are less than 2% of your body’s total. Removing them doesn’t shift sweat elsewhere.

How long does MiraDry Fresh recovery take?

Most people are back at a desk the next day. The first two days involve noticeable swelling and some tenderness — that’s normal. By the end of week one it’s mostly resolved. Exercise takes a bit longer; most clinicians suggest waiting 5–7 days before anything strenuous. The full picture — including sensation returning to normal — usually takes about a month.

Does MiraDry Fresh also reduce underarm odor and hair?

Odor, yes — and this is one reason some patients specifically seek out bromhidrosis treatment in Korea rather than locally. The apocrine glands that cause underarm odor sit at the same depth as sweat glands, so they’re treated at the same time. Hair reduction is more variable. It happens for many patients, but it’s a side effect of the treatment rather than the goal — results differ.

Is MiraDry available in English at Yaan Clinic?

Yes. The clinic handles a fair number of international patients, so English support is available from consultation through aftercare. WhatsApp (+82 10 5308-0499) is the easiest way to reach them before you arrive. The clinic is in Gangnam — about 5 minutes on foot from Bongeunsa Station, Exit 7.
