SkinPen Efficacy on Acne Scars on the Face and/or Back

Study Overview
=================
Brief Summary
-----------------
This single-center, clinical trial will take place over a 90 day course followed by 1-month and 6-month post treatment visits to assess the efficacy and tolerability of the SkinPen device when used on both men and women on the face and/or back.

Detailed Description
-----------------
At least 20 subjects of varying Fitzpatrick skin types will be admitted to the trial for treatment on their moderate to severe acne scars on the face and/or back. Implementation of needle depths ranging from 0.25 mm to 2.0 mm will depend on severity of scars and their location. Each subject will undergo 3 treatments in 30 day increments and will take pre-treatment images as well as 1-month and 6-months post treatment images. Assessment will be based on the Goodman and Baron's grading system, the Clinician's Global Aesthetic Improvement Scale, as well as a self-assessment.

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Severity of Acne Scars | Goodman and Baron's Qualitative grading system. Possible scores range from 1 = mild to 4 = severe. | Baseline, 1 month post treatment, and 6 months post treatment | 
| Clinician's Global Aesthetic Improvement Assessment (CGAIS) | Clinician's Global Aesthetic Improvement Assessment: minimal score is 1- Very much improved and, maximum score is 5 -Worse: The appearance is worse than the original condition | 1 month post treatment, and 6 months post treatment | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Photo Grading of Acne Scar Assessment | Photo grading of acne scars assessment was done using the following scale [Karnik J. et al, JAAD 2014, 71 (1)]: Grade- Term- Description 0 - Clear-- No depression is seen in the treatment area. Macular discoloration may be seen. - Very mild- - A single depression is easily noticeable with direct lighting (deep). Most or all of the depressions seen are only readily apparent with tangential lighting (shallow). - Mild-- A few to several, but less than half of all the depressions are easily noticeable with direct lighting(deep). Most of the depressions see are only readily apparent with tangential lighting (Shallow) 3- Moderate-- More than half of the depressions are apparent with direct lighting (deep) 4- Severe-- All or almost all the lesions can be seen with direct lighting (deep) | Day 1 (Baseline), Day 30, Day 60, 1-Month post treatment and 6 Month post treatment | 
| Subject Self-Assessment Using SASIS | Subject self-assessment was completed in 2 steps for self-assessed scar improvement scale (SASIS) and subject global aesthetic improvement scale (SGAIS): Based on a live assessment (subjects were provided with a hand mirror for assessment) of the subject while referring to pre-treatment images. Based on a comparison of pre-treatment images to current post-treatment images. Rating of Acne Scars 1-Exacerbation of acne scars 0 No change in the appearance of acne scars 1% - 25% improvement in the appearance of acne scars 25% - 50% improvement in the appearance of acne scars 3-50% - 75% improvement in the appearance of acne scars 4-75% - 99% improvement in the appearance of acne scars | One Month Post Treatment, 6 Month Post Treatment | 
| Subject Self-Assessment Using Global Aesthetic Improvement Scale (SGAIS) | The following rating scale was used for SGAIS: Rating and Description - Very much improved: Optimal cosmetic result - Much improved: Marked improvement in appearance from the initial condition, but not completely optimal - Improved: Obvious improvement in appearance from initial condition -No change: The appearance is essentially the same as the original condition - Worse: The appearance is worse than the original condition | 1-Month Post Treatment and 6- Month Post Treatment |
