Hyperhidrosis · August 2026
By Dr Tafadzwa, Founder of Lumina Aesthetics, Limerick
If antiperspirants stopped being enough a long time ago, you’re not alone — and you’re not out of options. Excessive sweating, or hyperhidrosis, is more common than most people realise, and it’s rarely talked about even though effective treatment exists.
Hyperhidrosis means sweating well beyond what your body needs for temperature regulation. It most commonly affects the underarms, hands, or feet, and for a lot of people it’s been a lifelong, quietly exhausting thing to manage — not something that responds to a stronger deodorant.
The same treatment used cosmetically for expression lines works on a similar principle here: it temporarily interrupts the nerve signals involved — in this case, the signals that trigger the sweat glands, rather than the ones that control muscle movement. The result is a significant, temporary reduction in sweating in the treated area.
Treatment is usually a series of small injections spread across the affected area — most commonly the underarms, though hands and feet can also be treated. Results aren’t immediate; it typically takes a few days for sweating to visibly reduce, building over the following week or two.
This tends to be most suitable for people with primary focal hyperhidrosis — sweating that isn’t linked to another underlying medical cause — that hasn’t responded well to prescription-strength antiperspirants. A proper consultation, including a look at your history, comes before any treatment plan.
Mild discomfort during the injections is normal, similar to other injectable treatments. There’s minimal downtime — most people are back to their day immediately. Sweating reduction builds gradually over the days that follow rather than happening instantly.
If excessive sweating has been affecting your confidence or daily life longer than you’d like to admit, it’s worth having an honest conversation about whether this could help. Full detail and pricing is on our hyperhidrosis treatment page.
It varies by individual, similar to cosmetic use — this is something to discuss at consultation rather than a fixed promise.
Underarms are the most commonly treated area, but hands and feet can also respond well — worth discussing your specific concern at consultation.
Most patients describe it as a brief, manageable discomfort rather than something painful.
This varies by provider and policy — worth checking directly with your insurer, as some do cover treatment for diagnosed hyperhidrosis.
