Permanent Relief from Underarm Sweat
For millions of people worldwide—and many right here in the Denver area — excessive underarm sweating, medically known as primary axillary hyperhidrosis, is far more than a simple cosmetic inconvenience. It is a persistent, distressing condition that impacts daily wardrobe choices, personal interactions, professional confidence, and overall emotional well-being. Constant fears of visible sweat rings, soaked garments, and ruined clothing fabrics lead many to structure their entire lives around hiding their symptoms.
While over-the-counter antiperspirants, clinical-strength topicals, and oral medications provide temporary relief for some, they frequently fall short for those experiencing moderate to severe hyperhidrosis. Non-invasive medical advancements have introduced long-term, permanent solutions, chief among them being miraDry.
As the first and only FDA-cleared, non-surgical treatment designed to permanently eliminate underarm sweat glands, miraDry has transformed the management of primary axillary hyperhidrosis.

How Normal Sweating Works
Your body has 2 to 4 million sweat glands designed to keep you cool. They come in two main types:
- Eccrine Glands: Found all over your body. They release clear, odorless water-and-salt sweat to lower your body temperature.
- Apocrine Glands: Found in hair-bearing areas like your armpits. They produce a thicker fluid that creates body odor when mixed with skin bacteria.
The Cause of Excessive Underarm Sweating
If you have primary axillary hyperhidrosis, your nervous system is essentially misfiring. It sends non-stop, overactive signals to the eccrine sweat glands in your armpits—forcing them to produce 4 to 5 times more sweat than your body actually needs for cooling.
How Excessive Sweating Happens: This process occurs in three main steps:
- Overactive Signaling: Your nervous system sends continuous, unnecessary signals to the armpit region.
- Gland Hyperactivity: The eccrine glands respond by producing a vast excess of moisture.
- Visible Sweat: The excess fluid collects on the skin, leading to persistent moisture and stained clothing.
The Real-Life Impact
Excessive sweating affects nearly 5% of Americans, causing emotional and daily disruption that goes far beyond simple physical wetness:
- Daily Wardrobe Decisions: Packing backup shirts, avoiding bright colors or silk, and wearing bulky layers even in warm weather.
- Social & Professional Anxiety: Hesitating to lift your arms in meetings, constant worry about visible sweat patches, and feeling self-conscious around others.
What is miraDry and How Does It Work?
miraDry is the first and only FDA-cleared, non-surgical medical treatment designed to permanently eliminate excessive underarm sweating (primary axillary hyperhidrosis). Unlike topical antiperspirants or Botox injections that temporarily mask symptoms or block signals, miraDry targets and destroys the root cause of the condition: the underarm sweat glands themselves.
The procedure works through a non-invasive, thermal approach tailored specifically to underarm physiology:
- Targeted Energy Delivery: The miraDry handpiece uses precise thermal microwave energy (5.8 GHz) to focus heat directly at the specific skin depth (the dermal-hypodermal interface) where underarm sweat and odor glands live.
- Selective Destruction: Sweat glands are rich in water, causing them to absorb the microwave energy readily. The thermal energy generates localized heat, permanently decomposing the sweat glands (thermolysis) without affecting surrounding tissues.
- Continuous Surface Protection: To ensure patient safety and comfort, the device simultaneously provides active contact cooling to the surface layer of the skin (the epidermis), keeping the outer skin completely protected throughout energy delivery.
Because your body does not regenerate sweat glands after adults reach maturity, the destroyed underarm glands are gone for good. Treatment yields an immediate, permanent reduction in underarm sweat (averaging 82% loss after a single protocol) with no effect on your body’s overall ability to cool itself, as underarm glands make up only ~2% of your body’s total sweat glands.
Safety & Regulatory Clearances
FDA Clearances and International Approvals
miraDry has received regulatory clearances for reducing underarm sweat, hair and odor. It is also used by healthcare providers around the world.
| Clearance or Approval | Year | Details |
|---|---|---|
| Underarm Sweat | 2011 | The FDA originally cleared miraDry for treating excessive underarm sweating, also known as primary axillary hyperhidrosis. |
| Underarm Hair | 2015 | The FDA expanded miraDry’s clearance to include the permanent reduction of unwanted underarm hair. |
| Underarm Odor | 2016 | The FDA further expanded miraDry’s clearance to include the reduction of underarm odor. |
| European CE Mark | 2013 and 2025 | miraDry received its original European CE Mark in December 2013 for treating excessive underarm sweating. Updated EU MDR certification covering sweat, odor and hair reduction was announced in 2025. |
| Worldwide Use | As of 2025 | miraDry reported that more than 500,000 patients had been treated worldwide, with providers operating across more than 14 European countries. |
Will Stopping Underarm Sweat Cause Overheating or Compensatory Sweating?
A common misconception is that halting underarm sweat will hinder the body’s cooling capacity or force sweat to erupt elsewhere.
- Thermoregulation Unaffected: The entire human body contains 2 to 4 million sweat glands, with the underarms accounting for roughly 2% of that total. Disabling this tiny fraction leaves the remaining 98% of sweat glands intact to maintain normal thermoregulation.
- No Compensatory Sweating: Unlike surgical procedures such as Endoscopic Thoracic Sympathectomy (ETS) — which carries a high risk of compensatory hyperhidrosis on the trunk or legs—miraDry creates localized tissue destruction without altering sympathetic nerve trunks. With more than 500,000 miraDry treatments performed worldwide, compensatory sweating is not an expected side effect — clinical evaluations show it is extremely rare for the body to redirect underarm sweat to other parts of the body.
Clinical Efficacy & Research Data
| Study Metric | Key Finding/Data Point | Source Study |
|---|---|---|
| Average Sweat Reduction | 82% average reduction at the 12-month follow-up | Hong et al., Dermatologic Surgery (2012) |
| Patient Satisfaction | 90% of patients reported satisfaction through 12 months | Hong et al., Dermatologic Surgery (2012) |
| Hyperhidrosis Severity Scale | 83.3% achieved a ≥2-point HDSS improvement at 7 months | Lee et al., Journal of Cosmetic and Laser Therapy (2013) |
| Underarm Hair Reduction | Approximately 70–75% average hair reduction at 12 months | Brauer et al., Dermatologic Surgery (2017) |
The Procedure: Step-by-Step
Understanding what to expect before, during, and after a miraDry session ensures a smooth, comfortable experience.
Phase 1: Pre-Treatment Care
- 4–6 Days Prior (Shaving): Shave your underarms completely to allow the provider clear access to the treatment zone.
- Day of Treatment (Arrival): Wear loose-fitting clothes and do not apply any underarm deodorant or antiperspirant.

Phase 2: In-Office Procedure
- Step 1 — Preparation & Mapping (10–15 Minutes): A starch-iodine test may be conducted to identify exact sweat focal points. A temporary, biocompatible grid template is applied to the skin to guide precise handpiece placement.
- Step 2 — Local Anesthesia Administration (15–20 Minutes): Local anesthetic (typically lidocaine with epinephrine and/or saline) is injected throughout the armpit to completely numb the area and form a protective cushion over deeper tissue.
- Step 3 — Energy Delivery & Cooling (40–60 Minutes): The practitioner systematically places the miraDry handpiece across the grid. Light suction draws the targeted skin into the device, where microwave energy disables sweat glands while active contact-cooling protects the outer skin.
Phase 3: Post-Treatment Care
- Immediate / Days 1–3 (Ice & Comfort): Apply towel-wrapped ice packs consistently for the first 48 to 72 hours. Over-the-counter anti-inflammatories and soothing topicals can help manage localized swelling and soreness.
- Days 5–7 (Recovery & Rest): Avoid strenuous activity, heavy lifting, or high-impact exercise to keep post-procedure swelling and inflammation to a minimum.
