Excessive Sweating Treatment Seoul

What causes excessive sweating

Primary focal hyperhidrosis usually begins in childhood or adolescence, often runs in families and affects specific areas symmetrically. Secondary hyperhidrosis, which is more generalised, can be caused by medications, thyroid problems, menopause, infections, diabetes or other medical conditions.

How a dermatologist diagnoses it

A dermatologist asks when sweating started, which areas are affected, whether it occurs during sleep and how it affects daily life. If secondary causes are suspected, blood tests may be suggested. A starch-iodine test can map the area of most active sweating before treatment.

Treatment options at The Heal Sinsa

Options include clinical-strength antiperspirants, Botox for hyperhidrosis injections into the underarms or other areas, and oral medication in selected cases. Botox temporarily blocks the nerve signals that activate sweat glands. Availability of specific devices varies by branch – confirm at consultation. Every plan starts with a 1:1 consultation with a Korean board-certified dermatologist and imaging-based skin analysis; you will not be pushed toward treatment you do not need. Pricing is confirmed after consultation; see pricing and payment.

Sessions, downtime & side effects

Botox effect typically begins within a week and lasts around 4–6 months or longer for underarms
Mild soreness or bruising at injection sites for a few days
Palm treatment may cause temporary hand weakness
Avoid during pregnancy, breastfeeding or with certain neuromuscular conditions

Home care

Use an antiperspirant at night on dry skin, wear breathable fabrics such as cotton, choose moisture-wicking socks and alternate shoes. Reduce triggers such as caffeine, alcohol and spicy foods if they worsen sweating.

When to see a doctor

See a doctor if sweating suddenly increases, is generalised, happens at night, or comes with weight loss, fever, palpitations or chest pain, as these may indicate an underlying medical condition.

Planning around your trip to Seoul

Underarm Botox takes only minutes and has little downtime, so it fits easily into a short trip; ask about combining treatments in one visit. The clinic is on the 7th floor of Sinsa Square near Sinsa Station, close to Garosu-gil (getting here), and English support is available on request (international patients).

Is Botox safe for excessive sweating?

Botox is widely used for underarm hyperhidrosis and is generally well tolerated when given by trained doctors. Side effects are usually mild, such as temporary soreness or bruising. Your dermatologist will check suitability before treatment.

How long does sweating Botox last?

Underarm results commonly last around four to six months and sometimes longer. Palms and soles may wear off sooner. Most people repeat treatment when sweating starts to return, often once or twice a year.

Will blocking sweat in one area cause sweating elsewhere?

Botox treats only small areas, so overall body temperature control is not affected. Some people notice slight changes elsewhere, but significant compensatory sweating is more associated with surgical sympathectomy than with injections.
