Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
30 total patients with moderate to severe acne scarring were recruited from 3/2007-5/2008 between two locations. Of these, 15 patients received treatment and 14 patients completed the full course of the study at the University of California, Irvine General Clinical Research Center.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
Subjects must not have been treated with other lasers, chemical procedures, or other cosmetic procedures on the area to be treated within 12 months of enrollment.
