Up to 20 subjects will be treated. Subjects will receive two (2) bilateral Ultherapy™ or Sham treatments of the axilla. The study hypothesis is that subjects who receive Ultherapy™ treatment will have a greater reduction in axillary sweating compared to subjects receiving Sham treatments. Follow-up visits will occur at 7 and 14 days following treatment #1, and at 7, 14, 30, 60 and 90 days following treatment #2. At each follow-up visit, assessments will be completed to compare the amount of axillary sweating compared to baseline.
