Hyperhidrosis

Radiofrequency microneedling can be an effective treatment for hyperhidrosis (excessive sweating) by targeting and disrupting the sweat glands through the combination of microneedles and radiofrequency (RF) energy. Here’s how it works:

Mechanism of Action:

1. Microneedles Penetrate the Skin:

  • The microneedling device uses fine needles to create micro-injuries in the skin, which allows the RF energy to penetrate directly into the deeper layers, specifically targeting the dermal layer where sweat glands are located.


2. Radiofrequency Energy is Delivered:

  • The microneedles emit RF energy as they reach the desired depth. This energy generates heat in the targeted area, which is controlled and focused. The heat can be delivered to a depth of 2 to 4 mm beneath the skin surface, reaching the sweat glands that are overactive in people with hyperhidrosis.


3. Thermal Damage to Sweat Glands:

  • The heat from the RF energy causes localized thermal damage to the sweat glands. This damage can result in the partial or complete destruction of the sweat glands, which helps to reduce or stop their activity.

  • The controlled heat also stimulates collagen production, which helps to tighten the skin and may reduce the size of the treated area, adding an aesthetic benefit.


4. Reduction in Sweat Production:

  • By targeting and reducing the number of functional sweat glands, radiofrequency microneedling helps decrease the production of sweat in the treated area.

  • This reduction is gradual, as the body heals from the micro-injuries over the weeks following treatment. Results can last for months or even longer, depending on the severity of the hyperhidrosis and individual response.

Areas Treated with RF Microneedling for Hyperhidrosis:

  • Underarms (Axillary Hyperhidrosis): The most common area treated with RF microneedling for hyperhidrosis is the underarm region, where it effectively reduces sweat production.

  • Palms and Soles: Although less common, RF microneedling can also be used for hyperhidrosis on the palms of the hands or soles of the feet.

Advantages of Using RF Microneedling for Hyperhidrosis:

  • Minimally Invasive: Compared to surgical options like endoscopic thoracic sympathectomy (ETS) or procedures like sweat gland excision, RF microneedling is minimally invasive.

  • Long-lasting Results: While results may vary, many patients experience a significant reduction in sweating that can last for several months or longer after a series of treatments.

  • Minimal Downtime: Most patients can resume normal activities quickly after the procedure, with only minor redness and swelling that typically resolves within a few days.

Treatment Course:

  • A typical treatment course for hyperhidrosis with RF microneedling may include 2-4 sessions spaced about 4-6 weeks apart, depending on the severity of the condition and the patient's response to the treatment.

  • Some patients may require maintenance treatments to sustain the results over time.


Radiofrequency microneedling offers a non-surgical solution for hyperhidrosis, providing patients with an option that reduces sweat production without the need for regular injections (like Botox for hyperhidrosis) or invasive procedures. It’s important for patients to have a consultation with a trained practitioner to determine if RF microneedling is appropriate for their specific needs and expectations.
