The use of high-intensity focused fractional radiofrequency (HIFRF) microneedling in the treatment of patients with primary axillary hyperhidrosis (PAH) is effective and well tolerated, according to study data published in the Journal of Drugs in Dermatology.

Several treatment options are available for PAH, all providing varying efficacy. HIFRF microneedling has been approved by the US Food and Drug Administration (FDA) for the treatment of facial wrinkles.
