Locating the Dermal-Fat Junction
Ultrasound-like depth mapping finds where sweat glands sit.
- 2–4mm: Target depth (dermal-fat junction)
- per axilla: Treatment area (grid of energy sites)
- ~15min: Setup time (marking and anesthesia)
- miraDry system: Device type (FDA-cleared 2011)
Pre-treatment mapping
Short placeholder text describing targeting depth mapping.
Microwave Thermal Energy Delivery
Microwave energy converts to heat right at the gland layer.
- Microwave: Energy type (~fixed frequency)
- ~60°C+: Peak temp (at focal depth)
- seconds/site: Exposure (per energy pulse)
- 1 visit: Sessions/visit (multiple pulses)
Thermal delivery mechanism
Short placeholder text describing microwave heat delivery.
Surface Cooling Protects the Epidermis
Active cooling keeps skin surface safe during treatment.
- Contact plate: Cooling method (circulating coolant)
- Kept low: Surface temp (protects epidermis)
- Cool→hot: Depth gradient (surface to junction)
- Wide: Safety margin (skin-sparing design)
Cooling system role

Permanent Gland Destruction Mechanism
Heat denatures glands so they cannot regenerate or regrow.
- Eccrine + apocrine: Gland types (both destroyed)
- Protein denaturation: Mechanism (thermal ablation)
- None expected: Regrowth (glands do not regenerate)
- Immediate: Onset (at treatment time)
Destruction pathway
Short placeholder text describing permanent gland ablation.
Permanent Sweat Reduction Outcome
One or two sessions give a lasting drop in underarm sweat.
- 1–2: Typical sessions (spaced weeks apart)
- ~80%+: Sweat reduction (reported average)
- ~1–2 weeks: Recovery (swelling resolves)
- Permanent: Durability (glands do not return)
Long-term result
Short placeholder text describing permanent treatment outcome.
Short placeholder highlight: permanent gland ablation confirmed by follow-up.
