Hyperhidrosis Botox in Myeongdong & Euljiro at Val:U Dermatology Clinic

Excessive sweating can stain clothes, make handshakes awkward and add stress on hot, humid Seoul summer days. Hyperhidrosis Botox at Val:U in Myeongdong works by blocking the nerve signals that switch on sweat glands in the treated skin. It is a short, in-office procedure with little downtime, and many people find it a practical option when antiperspirants alone are not enough. The clinic is a short walk from both Euljiro 1-ga and Myeongdong subway stations.

What is hyperhidrosis?

Hyperhidrosis means sweating more than the body needs to regulate temperature. Primary hyperhidrosis usually affects specific areas, such as the underarms, palms, soles or face, and often starts in adolescence. Secondary hyperhidrosis is linked to another condition or medication and tends to be more widespread.

If your sweating started suddenly in adulthood, affects your whole body, happens mainly at night or comes with weight loss or fever, it is worth seeing a physician to look for an underlying cause before cosmetic treatment.

How Botox reduces sweating

Sweat glands are activated by a chemical messenger released from nerve endings. Botulinum toxin temporarily blocks that release in the treated skin, so glands in the area produce much less sweat. Because the injections are very shallow, placed into the skin rather than muscle, they do not affect arm strength.

Other parts of the body continue to sweat normally, so temperature regulation is generally unaffected.

• Shallow injections in a grid pattern across the sweaty zone
• A starch-iodine test may be used to map active areas
• No effect on arm movement when placed correctly

Hyperhidrosis Botox price in Myeongdong

At Val:U, this treatment starts from KRW 89,000 excluding 10% VAT. The final price depends on the size of the treated area and the amount of product required. Larger or multiple areas will cost more. A confirmed quote is given at consultation.

Some people find it helpful to budget for a repeat treatment roughly once or twice a year, since the effect is temporary. If you have sweating in more than one area, ask the team which areas can be treated in the same session and how that affects the total.

What happens during treatment

The area is cleansed and the sweat zone is outlined. The doctor then places many small injections a short distance apart across the area using a very fine needle. Most people find underarm injections tolerable; cooling can help. The procedure is usually complete within half an hour, and you can dress and leave straight after.

Shaving the day before, rather than on the day, is often suggested so the doctor can see the skin clearly without fresh irritation. Wear a loose, dark top to your appointment for comfort afterward.

Side effects, results and aftercare

Side effects are usually minor: small bumps, pinpoint bleeding, bruising or tenderness. Some people notice slightly more sweating in untreated areas, known as compensatory sweating, though this is more commonly associated with surgical treatments. Rarely, product can affect nearby muscles.

Improvement typically starts within two to seven days. Duration varies but often extends several months, and many people repeat treatment when they notice sweating returning. For the first day, avoid heavy exercise, saunas and hot baths, and skip antiperspirant until the next day unless told otherwise.

Timing your visit around a Seoul trip

Since results start within days, many travelers book this early in their stay. Val:U is at 4F, 32 Myeongdong-gil: step out of Exit 6 at Myeongdong Station (Line 4) and walk about 340 m, or use Exit 5 or 6 at Euljiro 1-ga Station (Line 2), about 350 m away. The clinic opens seven days a week, until 20:30 on weekdays.
