Clinical Trial Summary

This single-center, the clinical trial is being conducted over the course of 90 days followed by 1-month and 6-month post-treatment visits in order to assess the efficacy and tolerability of the Sponsor's SkinPen device when used by men and women with the wrinkles of the neck.

Description:

A total of 32 subjects completed study participation. At visit 1 (baseline), subjects were screened for eligibility criteria, and those who qualified either completed day 1 procedures at the same visit or returned to the clinic up to 14 days after visit 1 to complete day 1 procedures at visit 2. On days 1, 30, 60, and 90, after completion of visit assessments, doctors or fellows at the testing facility (henceforth referred to as "clinic") treated each subject's wrinkles of the neck with SkinPen Precision System at depths of up to 2.5mm. During the post-treatment period, Clinical evaluations were conducted at visit 2 (day 1), visit 3 (day 30), visit 4 (day 60), visit 5 (day 90), visit 6 (1month post-treatment), and visit 7 (3 months post-treatment)

Type	Measure	Description	Time frame	Safety issue
Primary	Assessment of Wrinkle Severity Using the Lemperle Wrinkle Assessment Scale	Wrinkling in the neck region will be assessed according to the following definitions: Class 0: No Wrinkles Class 1: Just perceptible wrinkle Class 2: Shallow wrinkles Class 3: Moderately deep wrinkle Class 4: Deep wrinkle, well-defined edges Class 5: Very deep wrinkle, redundant fold	Day 1 and 3 Month Post Treatment
Primary	Clinician's Global Aesthetic Improvement Assessment (CGAIS)	This scale is completed in two steps: Based on a live assessment of the subject while referring to the subject's pre-treatment photographs of the neck, and; Based on a comparison of the subject's pre-treatment photographs to the current post-treatment photographs of the neck.; Rating and its Description; 1 --Very Much Improved: Optimal cosmetic result in this subject. 2--Much Improved: Marked improvement in appearance from the initial condition, but not completely optimal for this subject.; 3-Improved: Obvious improvement in appearance from the initial condition, but re-treatment is indicated.; 4--No Change: The appearance is essentially the same as the original condition. 5--Worse: The appearance is worse than the original condition.	3 Month Post Treatment
Secondary	Subject Global Aesthetic Improvement Scale (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 the 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 3 Month Post Treatment
Secondary	Transepidermal Water Loss of the Left Neck by Biox Aquaflux	The severity of wrinkles is more due to increased UV exposure through the driver's side window on the left side of the face and neck, due to this reason, the Principal investigator performed the TEWL on the left side of the neck. This test was pre-specified in the protocol. This procedure was performed 4-6 cm from the left lateral neck along the sternocleidomastoid muscle.; Biox Aquaflux is used to measure transepidermal water loss (TEWL) measurements which evaluate barrier function of the skin epidermal layer to determine the progress of epidermal healing after treatment.; Day 1 will be used as a baseline to analyze the change from baseline. TEWL is measured in g/m2/h. Normal rates of TEWL - from 2.3 g/m2/h to 44 g/m2/h - are compromised due to injury, infection, and/or severe damage as in the case of burns A decrease inTEWL reflects less water loss and an improvement in the skin's barrier properties; an absence of a change in treate	Baseline, 3 Months post treatment
Secondary	Vascular Density Measurements by Optical Coherence Tomography(OCT)	Vivosight, an Optical coherence tomography (OCT) device, is used to non-invasively gather topographical and histologic images of pre-and post-treated skin. This procedure was performed 4-6 cm from the left lateral neck along the sternocleidomastoid muscle. OCT measurements of the vascular density are reported in percentage (%) and were performed on the neck at 100 microns, 200 microns, and 500 microns. Scores multiplied by 1000 for analysis.; An increase in value indicates an increase in thickness and vascular density and skin tissue density.	Baseline (Day 1) and 3-Month post Treatment
Secondary	Skin Roughness Measurements by Optical Coherence Tomography(OCT)	Vivosight, an optical coherence tomography (OCT) device, was used to noninvasively gather topographical and histologic images of pre-and post-treated skin. This procedure was performed 4-6 cm from the left lateral neck along the sternocleidomastoid muscle. Roughness measurements were calculated from the histologic images using RA and RZ. Skin roughness is measured in micro-meters.; Ra is the average roughness of a surface. Rz is the difference between the tallest "peak" and the deepest "valley" on the surface.; A decrease in value indicates a decrease in skin roughness when Baseline and 3 months post-treatment are compared.	Baseline (Day 1) and 3 Months post treatment
Secondary	BTC 2000 Measurements- Energy Absorption	BTC-2000™ Features: High-Resolution Target Laser (µm) and negative pressure (mmHg & mbar); This procedure was performed 4-6 cm from the left lateral neck along the sternocleidomastoid muscle.; BTC 2000 was used to measure energy absorption of the skin.; The units for these measurements are Energy absorption - mmHg*mm; Decrease in values for energy absorption will be seen as Improvement	Baseline (Day 1) and 3 month post treatment
Secondary	BTC 2000 Measurements for Skin Elasticity	BTC-2000™ Features: High-Resolution Target Laser (µm) and negative pressure (mmHg & mbar); This procedure was performed 4-6 cm from the left lateral neck along the sternocleidomastoid muscle.; BTC 2000 was used to measure Elasticity values of the skin.; The units for these measurements are in % of the distance traveled in µm.; A decrease case in values for elasticity will be seen as an improvement after the treatments.	Baseline (Day 1) and 3 month post treatment
Secondary	BTC 2000 Measurements for Skin Deformations	BTC-2000™ Features: High-Resolution Target Laser (µm) and negative pressure (mmHg & mbar); This procedure was performed 4-6 cm from the left lateral neck along the sternocleidomastoid muscle.; BTC 2000 was used to measure viscoelastic deformation, elastic deformation, and ultimate deformation values of the skin.; The units for these measurements are in mm.; A Decrease in values for these deformations will be seen as an Improvement.	Baseline (Day 1) and 3 month post treatment
Secondary	BTC 2000 Measurements for Stiffness	BTC-2000™ Features: High-Resolution Target Laser (µm) and negative pressure (mmHg & mbar); This procedure was performed 4-6 cm from the left lateral neck along the sternocleidomastoid muscle.; BTC 2000 was used for stiffness. Stiffness is measure in mmHg/mm and an increase in values of BTC measurements for stiffness would be seen as an improvement upon treatment.	Baseline (Day 1) and 3 month post treatment
Secondary	Patient Satisfaction Questionnaires	Subjects completed a Sponsor-provided questionnaire regarding improvement in wrinkles, satisfaction with the treatment, and willingness to recommend the treatment to friends and family members	1 month post treatment
Secondary	Ultrasound Measurements	Ultrasound measurements were performed using a 75 MHz ultrasonic transducer interfaced to a DUB 6100 OEM System (Taberna Pro Medicum, Lüneburg, Germany). Density and skin thickness measurements were obtained from the scans and increases in these values suggest a thickening of the epidermal and dermal tissue.	Day 1, 3 Months post treatment.
