Hyperhidrosis Solutions: How AOKLINIK Can Help You Stay Dry

Do you find yourself constantly battling sweat, even in cool weather? Hyperhidrosis, or excessive sweating, can be a real challenge, affecting not just your clothes but your confidence too. At AOKLINIK, we’ve seen firsthand how hyperhidrosis can impact lives.

One of our patients, Ms J, from Singapore, struggled with excessive underarm sweating for years. Social situations were a nightmare, and she constantly worried about sweat stains and odors. After undergoing botulinum toxin injections at our clinic, she experienced an 85% reduction in sweating, which lasted for six months. Ms J now returns for repeat treatments and has regained her confidence.

Similarly, another patient, Mr M, opted for microneedle radiofrequency to address his underarm hyperhidrosis. After completing the recommended sessions, he saw a 75% decrease in sweating, with results lasting longer than botulinum toxin injections. Mr M appreciates the lasting effects and minimal downtime associated with this treatment.

At AOKLINIK, we understand how this condition impacts your daily life, and we're here to help. Let's explore what hyperhidrosis is, how it affects different parts of the body, and the effective treatments we offer, focusing especially on botulinum toxin injections and microneedle radiofrequency.

What is Hyperhidrosis?

Hyperhidrosis is more than just sweating a lot; it’s sweating when your body doesn't need to cool down. It can affect your underarms (axillary hyperhidrosis), palms (palmar hyperhidrosis), feet, face, and even more generalized areas. This condition can disrupt your day-to-day life, causing embarrassment and discomfort.

Types of Hyperhidrosis

  1. Primary Hyperhidrosis: This type isn’t linked to any other medical condition. It typically targets specific areas like your underarms, palms, feet, and face.

  2. Secondary Hyperhidrosis: This type is usually a side effect of an underlying medical condition or medication, leading to overall increased sweating.

Why Does Hyperhidrosis Happen?

The exact cause of primary hyperhidrosis isn’t fully understood, but it’s thought to involve overactive sweat glands triggered by the sympathetic nervous system. Genetic factors can also play a role, meaning if it runs in your family, you might be more likely to experience it. Secondary hyperhidrosis could be related to conditions like diabetes, thyroid issues, infections, or certain medications.

How Hyperhidrosis Affects Your Life

Excessive sweating can make everyday activities stressful. It can:

  • Cause Social Anxiety: Visible sweat stains can lead to embarrassment.

  • Create Physical Discomfort: Constant wetness can irritate your skin and cause infections.

  • Limit Work Efficiency: Sweaty palms can interfere with tasks requiring a good grip or handling delicate equipment.

Palmar Hyperhidrosis

If your hands are always sweaty, making it hard to hold a pen or shake hands confidently, you might have palmar hyperhidrosis. Here are some treatments:

  • Topical Antiperspirants: Strong antiperspirants with aluminum chloride can help.

  • Iontophoresis: This involves using electrical currents to reduce sweating in the palms and feet, with regular sessions needed.

  • Botulinum Toxin Injections: These can effectively block the nerves that trigger sweating.

Axillary Hyperhidrosis

Axillary hyperhidrosis, or excessive underarm sweating, can lead to damp clothes and unpleasant odors. At AOKLINIK, we offer advanced treatments to help you manage this condition.

Diagnosing with the Starch-Iodine Test

Before we start treatment, we may use the starch-iodine test to pinpoint the areas of excessive sweating:

  1. Application: We apply an iodine solution to your underarm area.

  2. Starch Dusting: Once the iodine dries, we dust starch over the area.

  3. Observation: The areas that sweat excessively will turn dark blue or black, helping us target the treatment precisely.

Botulinum Toxin Injections

One highly effective treatment for axillary hyperhidrosis is botulinum toxin injections. Here’s how it works:

How It Works

Botulinum toxin, commonly known as Botox, blocks the nerve signals that activate your sweat glands. When injected into your underarms, it temporarily stops these nerves, reducing sweat production.

What to Expect

  1. Consultation: We start with a thorough assessment to confirm the diagnosis and discuss your treatment plan.

  2. Starch-Iodine Test: We may perform this test to accurately locate the sweating areas.

  3. Preparation: We clean the underarm area and apply a topical anesthetic to minimize discomfort.

  4. Injection: Using a fine needle, we inject small amounts of botulinum toxin into multiple sites in your underarms.

  5. Aftercare: You can resume your normal activities right away. Results typically appear within a few days and can last for six months or longer.

Pros and Cons


  • Highly Effective: Significant reduction in sweating.

  • Minimal Downtime: Quick procedure with no major recovery period.

  • Proven Safety: A well-established track record of safety.


  • Temporary Results: Effects last about six months, requiring repeat treatments.

  • Cost: Can be expensive, especially with repeated sessions.

  • Possible Discomfort: Some patients may experience discomfort during injections.

Expected Outcomes

In my practice, I have treated over 100 patients with botulinum toxin injections for axillary hyperhidrosis. On average, about 85% of patients report a significant reduction in sweating, with improvements lasting up to six months. Patient satisfaction is generally high, with many returning for repeat treatments.

Microneedle Radiofrequency

Another cutting-edge treatment for axillary hyperhidrosis is microneedle radiofrequency (RF). This technique combines microneedling with radiofrequency energy to target and reduce sweat glands.

How It Works

Microneedle RF delivers controlled radiofrequency energy through microneedles into your skin, selectively heating and destroying overactive sweat glands while leaving surrounding tissues unharmed.

What to Expect

  1. Consultation: We conduct a detailed evaluation to determine if microneedle RF is right for you.

  2. Preparation: We clean the treatment area and apply a topical anesthetic.

  3. Microneedling: We use a device with fine needles to create microchannels in your skin.

  4. Radiofrequency Delivery: RF energy is delivered through the microneedles to ablate the sweat glands.

  5. Aftercare: You may experience mild redness and swelling, which typically subside within a few days. Multiple sessions might be needed for the best results.

Pros and Cons


  • Effective: Significant and lasting reduction in sweating.

  • Minimally Invasive: Less invasive than surgical options with minimal downtime.

  • Versatile: Can be combined with other treatments for enhanced results.


  • Multiple Sessions: Often requires several treatments for optimal results.

  • Mild Side Effects: Redness and swelling may occur post-treatment.

  • Cost: Can be more expensive compared to other treatments.

Expected Outcomes

For microneedle radiofrequency, we have treated over 100 patients at AOKLINIK. Approximately 75% of patients see a substantial decrease in sweating after completing the recommended sessions, with results lasting longer than botulinum toxin injections. Patients appreciate the lasting effects and minimal downtime associated with this treatment.
