Efficacy and tolerability of a microneedling device for treating wrinkles on the face

A microneedling pen has been cleared by the US Food and Drug Administration, indicated for improving the appearance of adult facial acne scars. The objective of this study was to assess the device's effectiveness for treating wrinkles of the face area.

Healthy adults seeking to improve the appearance of face wrinkles were enrolled (N = 35), receiving four monthly microneedling procedures by a trained aesthetician who treated the face skin per manufacturer instructions. Wrinkle assessments were performed by two trained blinded raters by comparing baseline images of each subject with images obtained at 90 days post-procedure. Subsequently, the two raters were unblinded for the Clinician's Global Aesthetic Improvement Scale (CGAIS) assessment. Subjects completed the Subject's Global Aesthetic Improvement Scale (SGAIS) and a Satisfaction Questionnaire at 30 and 90 days post-treatment.

The study was completed by 32 subjects with a mean (SD) age of 56.3 (5.0) years. Wrinkle assessments demonstrated significant improvement in the face areas (p < 0.001). The SGAIS scores showed significant improvements after 30 and 90 days post-treatment (for each, p < 0.001). The CGAIS scores also showed significant improvements at 90 days post-treatment (p < 0.001). Most subjects reported some level of improvement in their appearance at 30 days (73.3%) and 90 days (68.8%) post-treatment. The satisfaction questionnaire showed high levels of improvement in wrinkles (93.8%), satisfaction with the treatment procedure (87.5%) and would recommend microneedling to friends and family members (80.6%) on the face and neck.

Microneedling is a viable, minimally invasive option for treating wrinkles of the face.
