Evaluation of Safety and Efficacy of Morpheus8 Applicator for the Treatment of Focal Hyperhidrosis of the Axillae Using Radio Frequency

The InMode radio frequency Pro System with the Morpheus8 Applicator is a computerized system generating radio frequency energy, based on the underlying technology of Fractional RF. The Morpheus8 Applicator and 24 pin tip is used for the treatment of primary hyperhidrosis of the axillae

Study subjects will be consecutively screened and enrolled into the study. The study will consist of an active group that will receive 2 treatments with the InMode radio frequency Pro System with the Morpheus8 Applicator (with the 24 pin tip) and a sham group that will receive 2 sham treatments with the same InMode radio frequency Pro System and Morpheus8 Applicator (with a sham 24 pin tip). Treatment will be performed in a preheated controlled environment (T°≥22°C). Follow up visits will occur at 1 month, 3 months, and 6 months post treatment
