Living in or visiting a tropical paradise like Koh Samui is a dream, but for those suffering from hyperhidrosis (excessive sweating), the heat can turn daily life into a source of anxiety. If you find yourself constantly checking for wet patches on your clothes or avoiding raising your arms in photos, you are not alone. Botox for hyperhidrosis (sweaty armpits) is one of the most life-changing treatments we offer at LIV Clinic, providing a simple, non-surgical solution to a problem that antiperspirants often can’t touch.

Whether you are a local resident battling the humidity or a traveler wanting to enjoy your vacation without the worry of body odor and sweat stains, understanding how this treatment works is the first step to regaining your confidence.

Why Trust LIV Clinic With Your Comfort

Hyperhidrosis is a medical condition, not just a cosmetic concern. Treating it requires precise knowledge of the sweat gland anatomy to ensure effectiveness without affecting arm movement. At LIV Clinic, safety and efficacy are our top priorities.

Our medical director, Dr. Narathai Vichienkalayarut, has extensive experience in treating functional disorders with neuromodulators. We don’t just “inject and go.” We perform a thorough assessment, sometimes using an iodine-starch test to map exactly where your sweat glands are most active. This ensures that every unit of medication is placed for maximum impact. We use only authentic, premium brands like Allergan and Nabota, verified in your presence, so you can trust that you are receiving the highest standard of care in Bophut.

How Does It Work? The Science of Sweat Stopping

Many people are surprised to learn that the same medication used to smooth wrinkles can also stop sweat. It works by blocking the chemical signals from the nerves that stimulate your sweat glands.

When the body gets hot, your nervous system sends a message to your underarms saying, “Cool down!” In people with hyperhidrosis, this signal is stuck in the “on” position, causing you to sweat even when you are cool or calm. The injection acts as a shield, intercepting this message. The result? The glands simply stop producing sweat in the treated area. It does not affect your body’s ability to cool itself elsewhere, making it a safe and localized treatment.

The Procedure: A Quick & Painless “Lunchtime” Fix

We know that the idea of needles in the armpit sounds painful, but the reality is quite different. The skin in the underarm is not as sensitive as the face, and the needles we use are incredibly fine.

1. Preparation: We clean the area and apply a numbing cream to ensure your comfort.

2. Mapping: Dr. Narathai marks the area in a grid pattern to ensure even coverage.

3. The Injection: The treatment involves a series of quick, shallow injections just below the skin surface. The entire process takes about 20 to 30 minutes.

4. No Downtime: You can drive a motorbike, go shopping, or head back to work immediately afterward.

Expected Results and Timeline

Unlike wrinkle treatments which take a few days, sweat reduction can sometimes be felt even faster.

• Day 2-4: You will notice a significant reduction in dampness.

• Day 14: Full dryness is achieved. Most patients report an 80-90% reduction in sweat production. You may find you no longer need deodorant for wetness, only for fragrance if desired.

• Longevity: Results for hyperhidrosis typically last longer than facial treatments, often ranging from 6 to 9 months. Some lucky patients experience dryness for up to a year before needing a top-up.

Comparison: Botox vs. Other Sweat Solutions

Side Effects and Safety Profile

Safety is a common question when discussing Botox for hyperhidrosis (sweaty armpits). The good news is that this use of the toxin is extremely safe because it is injected superficially into the skin, not deep into the muscle.

• Bruising: Small pinpoint bruises may occur but are hidden by the arm.

• Muscle Weakness: In extremely rare cases, if the medication goes too deep, you might feel a slight weakness in your hand grip, but this is temporary. Our specialized technique prevents this.

• Compensatory Sweating: Unlike surgery, which often causes the body to sweat more in other places (like the back or chest) to compensate, this side effect is very rare with injections.

Cost and Value in Thailand

In 2026, Thailand remains one of the most affordable places to receive high-quality medical treatments. The price depends on the number of units required. An average treatment requires 50 units per arm (100 units total).

• Korean Brands (Nabota/Aestox): Offer excellent value and are very popular for body treatments.

• Allergan (USA): The premium option with a long track record.

We recommend a consultation to determine the exact dosage your body needs.

Aftercare Tips for Best Results

To ensure the medication settles correctly:

• Avoid Deodorant: Do not apply deodorant or antiperspirant for 12 hours after treatment to prevent irritation.

• Skip the Gym: Avoid heavy exercise or saunas for 48 hours. Heat can cause the medication to spread or metabolize too quickly.

• Keep it Clean: Wear a clean, loose cotton shirt to the appointment and immediately after to let the skin breathe.

Frequently Asked Questions

Does it hurt? Most patients rate the pain as a 2 or 3 out of 10. We use a strong numbing cream and ice to make it very tolerable. It feels like tiny pinpricks.

Will I sweat more in other places? This is a common myth associated with surgery (ETS), not Botox. With injections, compensatory sweating is extremely rare. Your body simply evaporates heat through the rest of your skin surface normally.

Can I stop wearing deodorant? Yes! Many of our patients stop using antiperspirants entirely. You may still choose to use a deodorant for scent, but the “anti-sweat” aluminum products become unnecessary.

Is it safe for teenagers? Hyperhidrosis often starts in the teenage years and can be socially devastating. We can treat younger patients with parental consent and a thorough medical evaluation to ensure it is the right path for them.

Does insurance cover this? In Thailand, aesthetic treatments are generally not covered by insurance. However, the cost at LIV Clinic is significantly lower than in Western countries, making it an accessible out-of-pocket expense for many.
