Comparison of Efficacy, Safety and Tolerability of Two Different 810 nm Diode Lasers for Hair Reduction

This side-by-side split body, blinded, randomized single-center study is comparing two
different 810 nm diode laser technologies for the purpose of permanent hair reduction to
determine the effectiveness and subject's tolerance for hair reduction. Twenty volunteers
will be enrolled into this study. Subjects will receive a total of 5 treatments of either
axilla or lower legs. 10 patients will have both axilla treated while the other 10 subjects
will have the lower legs treated. Placement to the axilla treatment group vs. the lower leg
treatment group is random.

Treatment areas will be randomized to receive Soprano SHR treatment or Light Sheer/Duet
treatment. One extremity (example: right axilla) will receive Soprano SHR treatment and the
contra-lateral extremity (example: left axilla) will receive Duet treatment. The treatments
will occur every 6 - 8 weeks and then there will be follow up visits at 1 month, 6 months,
and 12 months after the last treatment.
