What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Severity Change in Acne Scarring | The scale is a Physician Global Scarring Grading Scale, which counts and types scars by tallying up of the number and severity according to an organized grading system, where 0 is the lowest point value and represents no scarring. The theoretical highest score possible is an 84. The change in the score from the baseline to the follow up was collected. A negative change indicates a decrease in points (which indicates improvement). | Baseline and 1 month post treatment |

Secondary Outcome Measures
