Non-ablative Radiofrequency for Hyperhidrosis

Abstract

Hyperhidrosis is the most common sweating disorder and can cause significant interference on quality of life. Current treatment options include topical aluminum chloride, lasers, tap water iontophoresis, oral glycopyrrolate, botulinum A toxin, surgical excision of the skin and sweat gland layer, or sympathetic nerve blocks. In recent years, thermotherapy has emerged as an alternative treatment option. Radiofrequency thermotherapy (RFTT) utilizes electromagnetic radiation to produce electric current. When this current meets resistance within the tissue, it produces heat to denature proteins and permanently destroy sweat glands. Fractional radiofrequency differs from monopolar, unipolar, and bipolar radiofrequency as it allows unaffected regions to serve as a reservoir of cells to accelerate healing and maintain skin integrity. When compared to other types of radiofrequency, fractional delivery causes less patient discomfort and less downtime. Studies have shown a significant decrease in the amount of sweating and improvement in quality of life. Radiofrequency is a promising alternative treatment method to those with hyperhidrosis.
