Feasibility Study: Ulthera® System for the Treatment of Moderate to Severe Facial Acne

Study subjects will be assigned to one of two treatment groups. Both treatment groups will
receive treatment in the center of the forehead/temples, medial cheeks, and chin regions
using the 1.5mm and 1.0mm transducers.

- For Group A, both the 1.5mm and 1.0mm transducers will be used at 0.25J energy setting
and 0.20J energy setting, respectively.

- For Group B, both the 1.5mm and 1.0mm transducers will be used at 0.18J energy setting
and 0.15J energy setting, respectively.

Subjects will receive 3 Ultherapy treatments administered 2 weeks apart. Subjects will be
required to return for follow-up assessments at 14, 30, 60, 90 and 180 days following the
third Ultherapy treatment. Pre- and post-treatment photos will be taken. In addition, pre-
and post-treatment lesion counts and sebum measurements will be obtained.
