The underarm treatment is well-tolerated with topical anaesthetic. Hand and foot treatment can be more uncomfortable — topical anaesthetic and/or nerve blocks can be used.

Yes — this is a well-established medical treatment used for hyperhidrosis for decades. As a prescription medicine, it is managed with clinical oversight at DermaMedica.

Hyperhidrosis
Treatment

Q: How effective is the treatment?

Clinical evidence shows 80–90% reduction in sweating in most patients — a dramatic improvement that significantly impacts quality of life.

Q: Does it stop sweating completely?

In most patients, sweating is dramatically reduced rather than completely eliminated. For many patients, this represents a return to normal, socially manageable perspiration.

Q: How long does it last?

Typically 6–12 months for underarm treatment. Some patients find the interval extends with repeat treatment.

Specialist injections that temporarily block the nerve signals causing overactive sweat glands — providing significant, long-lasting relief from excessive sweating in the underarms, hands and feet.

About This Treatment

Hyperhidrosis
Treatment

Hyperhidrosis — excessive sweating — can have a significant impact on daily life, confidence and professional performance. Standard antiperspirants often fail to control the condition, leaving patients feeling self-conscious in social and professional situations.

Precision injections of neuromodulator into the affected sweat glands temporarily block the nerve signals that trigger sweating — providing significant, reliable relief for 6–12 months. This is the same principle as anti-wrinkle injections but applied to the autonomic nerve supply to sweat glands rather than facial muscles.

At DermaMedica, hyperhidrosis treatment is performed by our GMC-registered clinical team. A prescription consultation is required as the treatment uses a prescription medicine.

How It Works

The treatment
process.

Sweat Gland Mapping

The affected area is prepared and the treatment zone mapped — typically the axilla (underarm), hands or feet. A starch-iodine test may be used to identify the most active areas precisely.

Targeted Injections

Multiple small injections are made across the treatment area, delivering neuromodulator to the nerve terminals supplying the sweat glands.

Sweat Reduction

Over the following one to two weeks, the neuromodulator takes effect — blocking the nerve signals that trigger sweat gland activity. Patients typically experience a significant and sustained reduction in excessive sweating.

Your Treatment Journey

Before

Shave underarms 48 hours before treatment (for axillary hyperhidrosis). Arrive with clean, deodorant-free skin.

During

Multiple small injections across the treatment area. Mild discomfort — topical anaesthetic can be used for hands or feet. 30–45 minutes.

After

Mild tenderness for 24–48 hours. No other downtime. Resume normal activities immediately.

Results

Effect develops over 2 weeks. Patients typically experience 80–90% reduction in sweating.

Longevity

6–12 months depending on individual response. Regular treatment extends the interval between sessions.

Common Questions

Everything you
need to know.

How effective is the treatment?

Treatment for hyperhidrosis can be highly effective, with most patients noticing a significant reduction in excessive sweating within 1–2 weeks. Results typically last around 4–6 months, although this can vary between individuals.

Does it stop sweating completely?

The treatment can significantly reduce excessive sweating, but results vary from person to person. Most patients notice a major improvement, although some natural sweating may still occur.

Is it painful?

Most patients find the treatment very manageable. The injections are quick and use fine needles, with only mild and temporary discomfort during the procedure.

How long does it last?

Results typically last around 4–6 months, although this can vary between individuals.

Is it safe?

Yes — hyperhidrosis treatment is considered safe when performed by a qualified and experienced medical professional. A full consultation will be carried out to ensure the treatment is appropriate for you and to discuss any potential risks or side effects.
