Background: A microneedling pen has been cleared by the US FDA and is indicated for improving the appearance of facial acne scars in adults. Objectives: The aim of this study was to assess the effectiveness of this microneedling pen for treating wrinkles. This paper focuses on the results on the neck, an area of recent importance with video meetings placing physical stress on the neck area, leading to wrinkles. Methods: Healthy adult men and women were enrolled (N = 35). Subjects received 4 monthly microneedling procedures at depths of up to 2.5 mm. Wrinkle assessments were performed by 2 trained blinded raters by comparing images of each subject at baseline and at 90 days postprocedure. The 2 raters were unblinded for the Clinician's Global Aesthetic Improvement Scale assessment. Subjects completed the Subject's Global Aesthetic Improvement Scale and a questionnaire regarding satisfaction with the treated areas of the face and neck at 30 and 90 days posttreatment. Results: The study was completed by 32 subjects. Wrinkle assessments demonstrated significant improvement in the neck areas (P < 0.001). Both Global Aesthetic Improvement Scales showed significant improvements at 90 days posttreatment (P < 0.001). Most subjects reported some level of improvement in their appearance at 30 days (73.3%) and 90 days (68.8%) posttreatment. The satisfaction questionnaire showed high levels of improvement in wrinkles (93.8%), satisfaction with the results (87.5%), and would recommend microneedling to friends and family members (80.6%). Conclusions: Microneedling is a viable, minimally invasive option for treating wrin kles of the neck.
