miraDry is a non-surgical treatment for excessive sweating and odor issues. It uses thermal energy from microwave technology to permanently eliminate sweat glands, odor glands, and underarm hair.
- Rattinan Clinic is an authorized miraDry provider, offering proven results with clear before-and-after clinical outcomes.
- At Rattinan Clinic, we treat underarm sweat and odor using a specialized local anesthesia technique to minimize discomfort. Because miraDry uses high thermal energy to permanently eliminate sweat glands, odor glands, and axillary hair, patients can expect a 50–90% reduction in sweat after just one session.
At Rattinan Clinic, our FDA-cleared technology is operated by medical experts, and we offer free consultations for all patients.
What is miraDry?
miraDry is the latest medical innovation designed to permanently eliminate underarm sweat, body odor, and underarm hair without surgery. It is the only treatment cleared by the US FDA, and the Thai FDA to significantly reduce sweat and odor by treating the root cause which is the underarm sweat glands.
What Are the Causes of Body Odor?
Body Odor (Bromhidrosis) is not directly caused by sweat itself , but by the reactions between sweat, bodily secretions, and the bacteria living on the skin.
The main factors causing body odor are:
- The reactions between sweat and the bacteria (the main cause)
- Apocrine glands are sweat glands found mostly in areas with dense hair, such as the armpits and groin. Sweat from these glands is thick and consists of fats and proteins.
- Resident bacteria living on the skin which will break down fats and proteins found in apocrine glands. This produces distinct odours such as short-chain fatty acids, which are the primary cause of unpleasant body odor.
- Other trigger factors
Lifestyle can affect body odor as well. For example, stress triggers the apocrine glands to secrete sweat that is highly attractive to bacteria, intensifying the odor. Other factors include diet (pungent foods and alcohol), personal hygiene, and hormonal changes during puberty (when apocrine glands become fully active.)
Does Reducing Sweat Mean Reducing Body Odor?
Immediately. Because body odor does not come from the sweat itself, but from the reaction between sweat and skin bacteria, especially sweat secreted from the apocrine glands. Since this sweat contains fats and proteins, it provides the food for bacteria to thrive.
Why Is Underarm Odor Stronger Than Odor from Other Parts of the Body?
The underarm is the root cause of strong body odor because it contains a lot of both types of sweat glands. These include Eccrine Glands, which secrete clear sweat to regulate body temperature, and more importantly, Apocrine Glands, which are abundant in this area and secrete sweat rich in fats and proteins.
These compounds are initially odorless but serve as an excellent nutrient source for the resident bacteria in the underarm area. As bacteria decompose these nutrients, they produce Short-Chain Fatty Acids (SCFAs), which are responsible for strong, pungent body odor. On days when the body produces high levels of these odor-causing substances in a damp, enclosed underarm environment, the odor becomes more intense.
Can miraDry Instantly Reduce Underarm Odor?
The answer is yes. Because miraDry directly eliminates sweat glands and odor glands in the underarm area. Without sweat, the underarms remain dry, preventing bacteria from thriving. This can make the body odor immediately go away. Since there is no sweat for bacteria, body odor is significantly reduced right after the session.
miraDry is the latest innovation from the US that effectively eliminates underarm sweat and odor. It ends the struggle with dampness and unpleasant smells caused by underarm sweat glands, so you can live your life with confidence. Whether you’re at work or socializing, you’ll never have to carry a spare shirt again. Experience this treatment at Rattinan Clinic, Thailand’s first and only authorized miraDry provider.
What Are the Causes of Abnormal and Excessive Sweating (Hyperhidrosis) and Can It Be Treated?
Hyperhidrosis is a condition characterized by abnormal and excessive sweating. There are 2 main causes:
- Primary Hyperhidrosis is caused by a dysfunction in the autonomic nervous system, which overstimulates the sweat glands. It is often linked to genetics and typically occurs in specific areas (such as the underarms or palms).
- Secondary Hyperhidrosis is caused by other health issues, such as hyperthyroidism, diabetes, or as a side effect of certain medications.
If you are experiencing abnormal or excessive sweating, you should consult a dermatologist or a specialist for an accurate diagnosis to identify the root cause.
How Does miraDry Eliminate Sweat Glands?
miraDry works using a scientific approach to destroy the glands that cause underarm sweat and odor.
- Using Thermal Energy to destroy the glands in the underarm areas.
- The 5.8 GHz microwave energy, which is the thermal energy, is delivered to the dermis and fat layers (near the hair follicles).
- It destroys sweat glands, odor glands, and hair follicles in the underarm areas.
- The result is permanent because once these glands are gone, they cannot regenerate. This effectively stops the production of sweat and odor in the treated area.
- To protect the skin, the device uses Hydro-Ceramic cooling simultaneously as the thermal energy is delivered. This ensures the upper layers of the skin are protected from heat damage.
Who Is miraDry for?
miraDry is for someone struggling with underarm issues, including:
- Individuals seeking a permanent solution to underarm sweat and body odor.
- Individuals experiencing allergic reactions to roll-ons or deodorants, or those for whom sprays are no longer effective.
- Individuals with excessive underarm sweating or those diagnosed with Hyperhidrosis.
- Individuals who want to stop sweat from interfering with their workouts or sports performance.
- Those who have tried Botulinum Toxin A injections but were not satisfied with the results.
- Those struggling with strong body odor that persists even after showering or using a body spray.
- Those who want their perfume to stay true without being distorted by the smell of body odor or deodorants.

A Comparison of the Top 3 Underarm Sweat and Odor Reduction Technologies in 2026
A Comparison of the Top 3 Underarm Sweat and Odor Reduction Technologies in 2026 | |||
Topic | Botox | Fractional RF | miraDry |
Process | Uses injectable toxins to temporarily block sweat gland function. | Delivers RF energy into the skin layers to partially destroy sweat glands. | Uses 5.8 GHz Microwave energy to precisely eliminate sweat and odor glands. |
Post-Treatment Result | 70-80% reduction | 10-20% reduction | 70-80% reduction |
Frequency | Repeat every 4-6 months (2-3 times per year) | 4-5 times per year, every year | Only 1-2 times total |
Result Duration | Temporary results (repeated treatments for life) | Short-term results (Approximately once per month) | Permanent results (No long-term maintenance required) |
Long-Term Result | Temporary | Temporary | Permanent |
If you must choose how to treat sweat and odor, a comparison between Botox, Fractional RF, and miraDry reveals a significant difference in both cost-effectiveness and result duration.
If focusing on maximum cost-effectiveness, miraDry is your best choice because it uses Microwave energy to permanently and directly eliminate sweat glands. You only need 1-2 sessions and you are all set for life.
While Botox can immediately reduce sweat as effectively as miraDry, the results only last 4-6 months. This causes you ongoing expenses and frequent clinic visits, making the long-term cost much higher than investing in miraDry.
As for Fractional RF, it is considerably less effective because it offers only 10-20% reduction in sweat and requires multiple sessions. This may not be the ideal solution for individuals dealing with excessive sweating or pungent body odor.
So, if you are looking for a one-time and sustainable investment, miraDry is the most cost-effective technology, providing long-lasting results available.

- You can go back to your routine immediately and follow the doctor’s instructions strictly. The swelling will slowly go away in a month.
Why miraDry at Rattinan Clinic?
Because Rattinan Clinic is the first and only authorized miraDry provider in Thailand.
- There are proven results with clear before-and-after clinical outcomes.
- The doctors use the Single Shot local anesthesia technique, unlike other clinics that typically require multiple needle sessions. The advantages of this technique include minimal discomfort, fewer needle marks, and a lower risk of infection.
- Our doctors utilize Tumescent anesthesia, which is different from standard numbing methods. Because miraDry requires high thermal energy to be effective, proper anesthesia is needed. Without it, doctors cannot maximize the energy levels needed for better results due to patient discomfort.
