Hyperhidrosis Treatment in Korea: Botox Cost, Options & Risks

If sweat marks, slippery hands, or repeated clothing changes are disrupting your day, a low Seoul injection price can look like a quick fix. The safer first question is why you are sweating and which body area needs treatment. This article adds a focused decision guide to our Korean cosmetic procedures guide, without endorsing a clinic or promising a dry result.

What hyperhidrosis means—and when to seek medical care first

Hyperhidrosis is sweating beyond what the body needs to regulate temperature. It may be focal, commonly affecting underarms, palms, soles, or face, or more generalized. Primary focal hyperhidrosis often begins earlier in life; secondary sweating can be related to medicines or conditions such as thyroid disease, diabetes, infection, menopause, or neurologic disease.

The UK NHS hyperhidrosis guidance advises medical review when sweating has lasted at least six months, interferes with daily life, occurs weekly, happens at night, or may relate to another condition or medicine. Sudden generalized sweating, fever, chest pain, faintness, unexplained weight loss, or night sweats should not be packaged as a beauty treatment. Seek prompt medical assessment.

A consultation should document the areas, timing, triggers, medicines and supplements, family history, skin irritation, and impact on work or sleep. Tests are not automatically needed for everyone, but a doctor may order them when the history suggests a secondary cause.

Cost in Seoul: what public prices do—and do not tell you

Korea has no authoritative national cash tariff for cosmetic hyperhidrosis treatment. Two dated 2026 Seoul menus illustrate the range: SHIO Clinic lists 100-unit toxin treatment at KRW 109,000–300,000, depending on brand, while Page Lab lists hyperhidrosis treatment at KRW 300,000–500,000, with VAT excluded. These are commercial snapshots, not a market average, recommendation, or guarantee that the area and dose fit you.

Ask for a written total specifying:

• diagnosis and body area on each side;
• exact product, total units, and whether units are comparable across brands;
• physician fee, numbing, VAT, medicines, and review visit;
• expected duration and the price of repeat treatment;
• complication contact and whether an English treatment record is included.

Palms and soles may require a different dose, pain-control plan, and risk discussion than underarms. A cheap “100 units” headline does not show dilution, placement, product authenticity, or who injects it. Budget interpretation, travel, and local follow-up after returning home as part of the real cost.

Treatment options and recovery

Treatment usually starts conservatively. Clinical-strength antiperspirants may irritate skin but can be appropriate first-line care. Iontophoresis passes a weak current through water or wet pads and is often used for hands or feet; it requires repeated sessions and maintenance. Prescription topical or oral medicines may help some people, but dry mouth, blurred vision, urinary difficulty, constipation, overheating, and drug interactions require clinician review.

Botulinum toxin blocks nerve signals that activate sweat glands. The US FDA Botox label covers severe primary axillary hyperhidrosis inadequately managed by topical agents and describes multiple small intradermal injections across each underarm. That label is US regulatory information—not Korean prescribing authority—and does not make every body area or toxin brand equivalent.

Injection-site pain, bruising, swelling, headache, and temporary weakness can occur. Underarm treatment usually does not require surgical downtime, but tenderness may affect exercise or luggage carrying for a short period. Effect is temporary and repeat timing varies. Palmar injections can be painful and temporary hand weakness matters for drivers, musicians, and manual workers.

Microwave thermolysis aims to damage underarm sweat glands with energy and may also reduce odor and hair. A 2024 randomized controlled trial found significant sweat reduction with both toxin and microwave treatment through one year in a small within-patient study; outcomes differed for odor, hair, and preference. One study does not prove that either option is best for everyone. Swelling, pain, altered sensation, nodules, burns, and longer-lasting nerve symptoms need discussion.

Surgery, including sweat-gland procedures or sympathectomy, is generally reserved for selected severe cases after less invasive options. It can produce scars, infection, nerve injury, or sweating elsewhere on the body. It is not a casual travel add-on.

Risks and warning signs

Botulinum toxin products carry a boxed warning that effects may spread beyond the injection site. Seek urgent care for difficulty swallowing, speaking, or breathing; generalized weakness; double vision; or drooping that extends beyond the expected area. Serious spread appears uncommon at labeled dermatologic doses, but no injector can promise zero risk.

Also seek care for rapidly worsening redness, fever, pus, severe pain, hives, faintness, or other signs of infection or allergy. Reducing sweat in one small area does not usually stop the body from cooling, but extensive treatment, heat exposure, exercise, and medicines that reduce sweating can increase overheating concerns. Discuss summer travel plans.

Pregnancy, breastfeeding, neuromuscular disorders, previous toxin reactions, infection at the site, blood-thinning medicines, aminoglycoside antibiotics, and other medicines or supplements must be disclosed. Do not stop prescribed medicine without the prescriber.

Choosing a Korean clinic and planning travel

Use our clinic safety checklist. International patients can also check Korea's Medical Korea registered-institution system. Registration is an administrative safeguard, not proof of a particular outcome.

Ask who makes the diagnosis, who injects, how the treatment field is mapped, and how the product and dose will appear in your record. Confirm after-hours contact and what happens if weakness or infection develops after departure. Leave time for an early review instead of booking immediately before a flight.

FAQ

Is underarm Botox permanent?

No. Nerve signaling gradually returns, so repeat treatment may be needed. Duration varies by person, product, dose, and area; a clinic should not guarantee a fixed number of months.

Can it treat hands, feet, or the face?

Clinicians sometimes treat other focal areas, but pain, dose, nearby muscles, approved indications, and adverse effects differ. Ask whether the proposed use is authorized and evidence-based, and discuss hand or facial weakness explicitly.

Will sweating move somewhere else?

Compensatory sweating is especially associated with sympathectomy. It is not the usual expected effect of small-area toxin treatment, although your overall sweating pattern can change and needs individualized discussion.

How many days should I stay in Seoul?

There is no universal schedule. A short injection visit is not the same as confirmed recovery. Ask the treating physician when to exercise, use deodorant, enter a sauna, and fly, and leave time for review if your medical history or treated area raises concern.

A realistic next step

Start with a diagnosis, not a product menu. Compare two itemized plans only after a licensed clinician has considered secondary causes and conservative options. For some people, toxin or a device can reduce focal sweating; for others, maintenance, pain, side effects, or cost make another approach more sensible. Individual results vary, and choosing no procedure remains valid.
