Underarm sweat is usually thought of as a summer problem, but heated rooms and heavy clothing mean that many people deal with it in winter as well. In an expert column published by Mediafine on November 7, 2025, Dr. Wontak Choi of Yaan Clinic explains how miraDry addresses underarm sweat and odor without surgery, how the procedure is carried out, and what patients should keep in mind during recovery.
All treatments at Yaan Clinic are performed by a skilled, specialized medical team, delivering standardized, high-quality care based on the clinic's own proven clinical protocols.
What happened
Dr. Choi wrote the column to explain miraDry to readers who live with hyperhidrosis (excessive sweating) or osmidrosis (underarm odor). He notes that when sweating goes beyond the occasional and starts to affect daily life, it can also become a source of psychological stress. Avoiding social situations, discomfort at work and limits on what clothing to wear are among the effects he describes, which is why he frames these conditions as an issue of quality of life rather than appearance alone.
In the column, he compares miraDry with the options that were common in the past:
- Surgical removal of sweat glands: effective, but recovery takes longer and scarring is possible
- Regular Botox injections: no incision, but the effect is temporary and has to be repeated
- miraDry: no incision, and the treated sweat glands are destroyed, which Dr. Choi explains is why the effect can be maintained over the long term
Why it matters for international patients
For visitors planning treatment during a short trip to Seoul, the practical details of miraDry are important. As Dr. Choi describes, the procedure is done under local anesthesia and usually takes about an hour or less. There is no bleeding to manage and no stitches are needed afterwards, so most people can return to their daily routine quickly.
He also points out that the distribution of sweat glands and the condition of the skin differ from person to person. A thorough consultation and an accurate diagnosis before treatment are therefore necessary, especially for patients who are deciding on treatment shortly after arriving in Korea.
About miraDry
miraDry is a device that uses microwave energy to selectively target the sweat glands in the underarm. While energy is delivered beneath the skin, a cooling system works on the skin surface to protect it from heat damage. The treatment acts on both eccrine glands, which produce sweat, and apocrine glands, which are linked to odor. For this reason, Dr. Choi notes that a single session can address both excessive sweating and odor.
During the procedure, anesthetic is injected into the treatment area and energy is applied through a dedicated handpiece. On recovery, the column explains:
- Mild swelling or temporarily reduced sensation is common and usually settles within a few days
- Keeping the area clean and using cold compresses can help recovery
- Temporary bruising or pain can occur in rare cases and is generally mild
- For thin or sensitive skin, the energy level should be adjusted to reduce the risk of side effects
- Saunas, intense exercise and alcohol should be avoided after treatment, and the area should be protected from irritation
