How does Botulinum Toxin work?

Botulinum Toxin temporarily blocks the nerve signals that stimulate the sweat glands. This significantly reduces sweating in the treated area while allowing the body to sweat normally elsewhere.

What to expect during treatment

• The treatment area will be cleansed.
• A fine needle is used to inject botulinum toxin just under the skin in a grid-like pattern.
• The procedure takes around 20–30 minutes and requires no downtime.
• You can return to most activities immediately after treatment.

Aftercare Advice

To ensure the best results, follow these aftercare guidelines:

• Avoid rubbing or massaging the treated area for 24 hours.
• Do not use strong antiperspirants or deodorants for 24 hours.
• Avoid excessive heat exposure, such as saunas or hot showers, for 48 hours.
• Refrain from vigorous exercise for 24–48 hours.

When will I see results?

• Most patients notice an improvement in sweating within 3–7 days.
• The full effect is usually visible within 2 weeks.
• Results typically last between 4–6 months before repeat treatment is required.

Possible side effects 

Botulinum Toxin is a safe and well-tolerated treatment, but mild side effects can occur, including:

• Temporary redness, swelling, or bruising at the injection site.
• Mild discomfort or a feeling of tightness in the area.
• If treating the hands or feet, temporary weakness in nearby muscles may occur.

Serious side effects are very rare but may include allergic reactions or difficulty swallowing if Botulinum Toxin spreads beyond the intended area. If you experience any unusual symptoms, seek medical advice immediately.

Who should not have Botulinum Toxin for Underarm Sweating

Botulinum Toxin is not recommended for individuals who:

• Have had an allergic reaction to botulinum toxin in the past.
• Have neuromuscular conditions (e.g., Myasthenia Gravis or Lambert-Eaton syndrome).
• Are pregnant or breastfeeding.
• Have a skin infection or irritation in the treatment area.

Follow Up & Future Treatments

A follow-up appointment may be offered to assess your results. If necessary, additional treatments can be discussed.

To maintain results, repeat treatments are usually needed every 4–6 months.
