Quick answer
What is hyperhidrosis Botox?
Hyperhidrosis Botox treats primary axillary hyperhidrosis — sweating in the underarms beyond what the body needs to cool down. Botulinum toxin injected just under the skin blocks the chemical signal that activates sweat glands, cutting sweat production in the treated area for months.
It does not affect your body’s overall ability to cool down, because the underarms are a small share of total sweat glands. Palms can be treated too — see hand Botox.

How Hyperhidrosis Botox works at Umi
Every visit is doctor-led and explained in English, from the first skin check to aftercare.
- Consultation
The doctor confirms the sweating pattern and rules out medical causes needing separate care.
- Mapping the area
The hair-bearing underarm area is marked in a grid; a starch-iodine test can show the most active zones.
- Superficial injections
Many small injections just under the skin across each underarm.
- Aftercare
Skip deodorant, hot baths and heavy exercise for the rest of the day.
Before & after
How Botox stops heavy sweating
Blocking the nerve signal to sweat glands in the underarm skin dramatically reduces sweating while the glands stay intact.
Sweating begins to drop.
Full dryness for most people.
Effect fades gradually; retreat when needed.

FAQ
Hyperhidrosis Botox questions
Is underarm Botox painful?
The underarm skin is less sensitive than the palms. Most people feel only small pinches, and ice helps.
Will I sweat more elsewhere?
Some people notice slight compensatory sweating, but it is usually minor because only a small area is treated.
Does it stop body odour?
Odour often improves because there is less sweat for bacteria to break down, though it is not a guaranteed cure.
How long does it last?
Typically 4–9 months, varying from person to person.
Do foreigners pay more?
No. International patients pay the same price as local patients at Umi Clinic.
