Up to 20 enrolled subjects will be treated. Subjects will receive two Ulthera® treatments on the axillas provided 30 days apart. Follow-up visits will occur at 7, 30, 90 and 180 days following the last treatment. Protocol amendment: The study was expanded to enroll an additional 20 subjects into Group A.
This study is a prospective, single-center, randomized clinical trial. Up to 20 subjects who are naïve to Ultherapy for treatment of hyperhidrosis will be enrolled and treated at a 2.0mm depth at two different treatment densities (Group A and Group B). Group A will include up to 10 treated subjects. Subjects receiving treatment in a 3 x 4 grid, 12 treatment squares, 60 lines of treatment per square, at one treatment depth (2.0mm), at 0.30 J of energy. Group B will include up to 10 treated subjects. Subjects receiving treatment in a 3 x 4 grid, 12 treatment squares, 40 lines of treatment per square, at one treatment depth (2.0mm), at 0.30 J of energy. Gravimetric sweat production measures and starch iodine tests will be completed at baseline, treatment visit #2, and at all follow-ups for all study groups. Digital images of the starch iodine test will be obtained. Hyperhidrosis Disease Severity Scale (HDSS) scores will be obtained at baseline, each treatment visit, and at all follow-ups for all study groups.

HDSS score reduction
HDSS score reduction from a 3 or 4 at baseline to a 1 or 2 at 30 days post-treatment #2.
Time frame: Day 30 post-treatment #2
Sweat production by gravimetric measure
Reduction in spontaneous axillary sweat production assessed by a gravimetric method, as measured by a 50% reduction or more compared to baseline. • Gravimetric method is performed by drying the surface of the skin, then applying a pre-weighed filter paper to the axilla for a period of time measured by a stopwatch. The paper is then weighed and the rate of sweat production is calculated in mg/min.
Time frame: 7 Days post-treatment #2

Starch iodine test
Starch iodine test to assess area of efficacy with digital images. • Starch Iodine test is performed by applying an iodine solution to the sweaty area. After it dries, starch is sprinkled on the area. The starch-iodine combination turns a dark blue color wherever excess sweat is present. Digital images of the starch iodine test will be obtained.
