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

Microneedling is a relatively new, minimally invasive technique originally developed for skin rejuvenation. Controlled micro-injury to the dermis via the application of several small needles connected to a motorized device stimulates the wound healing process, resulting in the formation of new tissue and blood vessels. The SkinPen by Crown Laboratories is an FDA-cleared microneedling device proven to improve the appearance of acne scars This study evaluates the clinical performance of the SkinPen device for the treatment of signs of aging on the back of the hand. We hypothesize that the SkinPen device will produce a significant improvement in dorsal hand appearance at 3 month post treatment visit, when compared with baseline scores. The assessments will be based on the Clinician's Global Aesthetic Improvement Scale, and the Subject's Global Aesthetic Improvement Scale at the 3 month post treatment visit.
