🌸 Quick answer

How well does underarm Botox stop sweating? Underarm Botox blocks the chemical signal that tells the sweat glands in the armpit to work, so most people notice a strong reduction in sweating. Many small injections are placed just under the skin across each underarm. Effects begin in 3–5 days, full dryness arrives in about 1–2 weeks, and results typically last 4–6 months. Less moisture can also mean less odour. Many people repeat it twice a year.

What is underarm Botox?

Underarm Botox is a treatment for excessive armpit sweating, also called axillary hyperhidrosis. Botulinum toxin is placed in a grid of tiny, shallow injections where the sweat glands are most active. It does not remove the glands; it quietens them for several months.

It is part of our wider hyperhidrosis Botox care, which can also treat the hands and feet — see hand Botox and foot Botox.

Underarm Botox FAQ

How long does underarm Botox last?

Underarm Botox typically lasts 4–6 months. Many people repeat it twice a year, often timing a session before summer or a holiday in a hot climate.

Does underarm Botox hurt?

You feel a series of small, quick pinches from a fine needle. The injections are shallow, the session takes 10–15 minutes and most people find it very manageable.

Will I sweat more somewhere else?

Some people notice slightly more sweating in other areas, but it is usually mild. The underarms make up only a small part of the body's total sweating.

Does underarm Botox reduce odour?

It can. Odour comes from bacteria breaking down sweat, so less moisture often means less smell. It does not change body odour from other causes.

Can I do underarm Botox on a trip to Seoul?

Yes. It takes 10–15 minutes and has no downtime. Avoid saunas and intense workouts for 24 hours, and dryness builds over the following 1–2 weeks.
