Efficacy and Tolerability of SkinPen on Male and Female Subjects' Wrinkles of the Neck

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)
