A Proof of Concept Study to Evaluate the Efficacy and Tolerability of Skinpen on Male and Female Subjects' Dorsal Hands as a Treatment of Hand Aging

A total of 18 subjects will be enrolled in this study. These patients will be treated three times over the dorsum of the hand from the wrist to the knuckles each month for three months, followed by one follow-up visit at 3-months post-treatment. Blueberry and Crown Laboratories will be responsible for recruitment efforts. Subjects will be numbered sequentially in the order in which they qualify for entry into the study. 3.2 Primary Endpoints • Clinician's global aesthetic improvement assessment (CGAIS) at 3-months post-treatment. 3.3 Secondary Endpoints * Subject's global aesthetic improvement assessment (SGAIS) at 3-months post-treatment. * Monitoring of adverse events throughout the course of the study. Safety Subject diaries will be monitored for resolution of anticipated treatment responses. 3.4 Exploratory Endpoints • Bioinstrumentation: TEWL, hydration, elasticity, skin thickness measurements at each visit.
