Efficacy of Micro-excisional Skin Removal by Micro-coring Device in Treatment of Wrinkles and Laxity of Face and Neck

Study Overview
=================
Brief Summary
-----------------
This is a prospective, multi-center, pilot study evaluating effectiveness of micro-excisional skin remodeling by micro-coring skin in subjects meeting the Inclusion Criteria. Subjects will undergo bilateral treatment on the face and neck (upper and lower cheek, upper and lower lip, periocular and perioral areas, submandibular and middle neck, etc). The exact treatment area(s), choice of treatment density are left to the Investigator's discretion and subject's consent. Up to 3 treatments are allowed with a minimum of 30-day between the consecutive treatments.

Detailed Description
-----------------
The study will enroll up to 50 subjects at 6-8 investigational sites. It will evaluating effectiveness of a micro-coring device for micro-excisional skin remodeling in subjects with moderate to severe wrinkles of face and neck who meet the Inclusion/Exclusion Criteria. The choice of treatment density is at the investigator's discretion with the subject's consent. Up to 3 treatments may be performed with a minimum of 30-day interval between the consecutive treatments. Subjects will undergo bilateral micro-coring of skin on the face and upper neck, including but not limited to upper and lower cheek, upper and lower lip, periocular and perioral areas, submandibular and upper neck. The exact area(s) of treatment are left to the Investigator's discretion and subject's consent. The subjects will be evaluated at each visit and following data will be collected: The incidence and severity of systemic and local adverse events. Wrinkle severity score assessed using the Lemperle Wrinkle Severity Scale. Changes in skin laxity assessed by Laxity Scale. Canfield Image Analyses. Needle and/or punch biopsy (in some subjects). Overall aesthetic improvement using the following scales: Subject and PI Global Aesthetic Improvement Scale (GAIS) Subject Satisfaction Scale Rhytides and Laxity Scale Lower face assessment Investigator evaluation of device usability and functionality. Data Analysis: Analyses will be conducted per measurement tools listed. Statistical analysis will include but will not be limited to T tests, univariate and multivariate analysis.

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Assess wrinkle reduction for moderate to severe wrinkles at 90 days post treatment based on the Lemperle Wrinkle Scale | Assess wrinkle reduction in wrinkle severity score from the baseline assessed by Independent Reviewer(s) using the Lemperle Wrinkle Severity Scale. No wrinkles = 0; Just perceptible wrinkles = 1; Shallow wrinkles = 2; Moderately deep wrinkles = 3; Deep wrinkles, well-defined edges = 4; Very deep wrinkles, redundant fold = 5 | 90-day post-treatment | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Assess skin laxity Improvement at 90 days post treatment | Improvement in skin laxity score from the baseline assessed by Independent Reviewer using Laxity Scale and supplemented by the Canfield Image Analyses. Global Aesthetic Improvement Scale: 3 Very Much Improved; 2 Much Improved; 1 Improved; 0 No Change; - 1 Worse; - 2 Much Worse; -3 Very Much Worse. | 90-day post-treatment | 
| Assess skin for new collagenases | Histological changes in treated skin when compared to untreated skin consistent with new collagenases | 60, 90, 180-day post treatment |
