How long does microwave sweat gland treatment take to work for underarm sweating?

The device delivers microwave energy to the underarm area, where heat targets sweat glands. Some people notice less moisture as the area recovers, but the early appearance can be affected by swelling, numbness, tenderness, or temporary altered sensation. The result depends on sweat pattern, treatment settings, gland distribution, and how the skin heals. One underarm can settle faster than the other.

This treatment focuses on the underarms. Sweating from the hands, feet, face, or whole body needs a separate assessment and may have different causes and options.

Use the prescribed cooling or comfort measures and keep the area clean as directed. Avoid shaving, deodorant, strenuous exercise, hot baths, and tight clothing until the clinic says they are suitable again. Do not massage a tender area unless instructed. Keep follow-up appointments so the clinician can assess sweating, sensation, swelling, and skin colour before deciding whether anything further is needed.

Contact the clinic if pain or swelling is increasing, the skin becomes very red or blistered, or numbness or weakness is troubling you. Seek prompt care for fever, pus, spreading warmth, severe pain, or rapidly worsening swelling. If sweating suddenly affects other body areas or occurs with dizziness, chest symptoms, or unexplained illness, arrange medical assessment.

Ask when you should expect less underarm moisture, how the treatment will be tested at review, and which activities or products to avoid. Discuss previous underarm procedures, medicines, implanted devices, skin sensitivity, and whether your sweating pattern suggests another cause.
