Change in Acne Scar Severity
Change in acne scarring severity from baseline to nine months will be assessed using the Global Scale for Acne Scar Severity (SCAR-S) scale. The SCAR-S is a validated scale used to assess the severity of acne scarring using a 6-point scale ranging from 0 ("Clear, no visible scars from acne") to 5 ("Very Severe; entire area with prominent atrophic or hypertrophic scars") such that higher scores are indicative of more severe scarring. Two independent blinded dermatologists will rate before and after treatment images using the SCAR-S scale. Results will be summarized by study arm using descriptive statistics.
Change in Clinician Graded Global Assessment of Improvement Scale (GAIS) score
Change in aesthetic success from baseline will be evaluated using the Clinician's Global Assessment of Improvement Scale (CGAIS). The CGAIS evaluates overall efficacy and cosmetic outcomes of the treatment. The CGAIS is based upon a 7-point scale ranging from -3 ("Greatly worsened") to +3 ("Greatly improved"), with 0 ("No change") as the midpoint. Two independent unbiased blinded dermatologists will conduct live/photographic assessments to evaluate patients at baseline, Month 2, Month 3, Month 4, Month 6, and Month 9. Results will be summarized by study arm using descriptive statistics.
Overall Patient Satisfaction
Overall patient satisfaction will be assessed throughout the study using an item from the Patient Satisfaction Questionnaire (PSQ) completed during each visit. This question asks patients to select the option that better represents the change in how their skin looks using a 7-point scale ranging from -3 ("Greatly decreased") to +3 ("Greatly increased"), with 0 ("No change") as the midpoint. Scores will be summarized by study arm using descriptive statistics.
Patient Assessment of Acne Scarring
Patient assessment of acne scarring will be assessed throughout the study using an item from the Patient Satisfaction Questionnaire (PSQ) completed during each visit. This question asks patients to select the option that better represents the change in acne scarring in the area treated using a 7-point scale ranging from -3 ("Greatly decreased") to +3 ("Greatly increased"), with 0 ("No change") as the midpoint. Scores will be summarized by study arm using descriptive statistics.
Dermatology Quality of Life
Dermatology quality of life will be assessed using the Dermatology Life Quality Index (DLQI). The DLQI is a standardized 10-item dermatology scale which determines how much impact a skin condition has had on life quality. Patients are asked to consider how much their skin problem has affected their life over the prior week when responding to each question. Questions are subjectively answered by patients using the following choices: "Very much" (= 3 points), "A lot" (= 2 points), "A little" (= 1 point), and "Not at all" or "Not relevant" (= 0 points). Scores are summarized for an overall possible range of 0-30, such that higher scores are indicative of greater dermatology-related life quality impairment. Results will be summarized by study arm using descriptive statistics.
