How Successful Is Botox Treatment for Hyperhidrosis?

Introduction

For individuals struggling with excessive sweating (hyperhidrosis), Botox injections can offer a meaningful reduction in perspiration. At Bayswater Dental Clinic, we apply evidence-based techniques to help you gauge the likely success of treatment, the factors influencing outcomes, and how long results tend to last. If you’d like an assessment specific to you, call 020 7229 4627 or email info@bayswaterdental.co.uk to schedule a consultation.

Success Rates & Patient Satisfaction

Botox has proven effectiveness for hyperhidrosis. Studies and clinical practice suggest:

Many patients experience an 80–90% reduction in sweating in the treated region.
Results are typically noticeable within a few days to two weeks after treatment.
Satisfaction rates are high, with most users reporting improved comfort, confidence, and quality of life.
The effect is temporary, so maintenance injections are needed to sustain results.

Factors That Influence Success

The degree of improvement depends on several variables:

Treatment area: Underarm hyperhidrosis generally responds better than palm or foot sweating.
Severity: Patients with moderate sweating often get stronger relative results than those with severe, widespread sweating.
Precision of injection: Coverage of all active sweat gland sites is critical.
Dosage used: Adequate units, appropriately spaced, improve outcomes.
Patient anatomy and physiology: Skin thickness, gland density, and individual neuromuscular sensitivity all play a role.
Maintenance timing: Repeating treatments at optimal intervals helps preserve success.
Lifestyle and external triggers: Stress, temperature, hormones, and medications may influence sweat production.

What You Can Expect (Treatment Process & Outcome)

On the day of treatment, small amounts of Botox are injected into the region of concern using a grid or anatomical landmarks. Discomfort is usually mild and short-lived with numbing techniques. Afterward:

You may see a visible reduction in sweat within 3–7 days.
Maximum effect often is reached by 10–14 days.
Over time, as the Botox wears off, sweating may gradually return.
Many patients repeat injections every 4–6 months to maintain the benefit.

Cost

To learn the cost for your hyperhidrosis Botox treatment, please call the clinic. We will consider the area to treat, the number of injection sites, and your medical history before quoting a price.

Aftercare

Avoid rubbing or massaging the treated zone for at least 24 hours.
Refrain from strenuous exercise and heat exposure for the first 24–48 hours.
Stay upright and avoid leaning or pressure on the area.
Mild redness or discomfort is normal and should fade within a day or two.
Contact us if you notice persistent weakness in nearby muscles or swelling.

Suitability

Botox is a good option if:

You experience localized excessive sweating in areas like underarms, hands, feet, or face.
You are otherwise in good health.
You accept the need for repeat treatments.

You might not be a candidate if:

You have neuromuscular disorders.
You are pregnant or breastfeeding.
You have infection or inflammation in the intended area.
You are on certain medications that interact with botulinum toxin.

We screen your medical history carefully to confirm whether Botox is an appropriate option for you.

Alternatives & Complementary Treatments

Prescription-strength antiperspirants for mild cases
Iontophoresis (electrical current therapy — especially for palms or feet)
MiraDry or other energy-based devices to destroy sweat glands
Oral medications (anticholinergics) — for more systemic control
Surgical sympathectomy — a more invasive approach for severe cases

During your consultation, we’ll help you weigh which option or combination fits your needs best.

Frequently Asked Questions

How long does Botox reduce sweating?

Typically, the effect lasts 4 to 6 months, though this can vary. Many patients get repeat treatments before full return of sweating.
Can Botox ever stop working?

Over time, you might notice that the duration shortens slightly. However, many patients enjoy consistent results with regular maintenance.
Is there a complete “cure” for hyperhidrosis?

Botox is not permanent; it controls symptoms while active. Other interventions like sweat gland ablation or sympathectomy are more permanent but carry higher risk.
Will I sweat somewhere else more (compensatory sweating)?

Some people experience increased sweating in untreated zones. This is usually mild and manageable.
Does Botox treat all types of sweating?

It works best for focal (localized) excessive sweating. Widespread or whole-body sweating may need systemic treatments or other interventions.
