Microneedling is a common cosmetic procedure for improvement of wrinkles, acne, scars, and other conditions. Various microneedle (MN) patches have been developed as home care therapy for wrinkles and skin texture. Most of them are made of soluble and absorbable needles. To evaluate the efficacy and safety of non-absorbable magnesium (Mg) MN patches on under-eye wrinkles. A total of 20 subjects aged 27 to 58 years was enrolled in the study. The subjects applied Mg MN patches on the under-eye wrinkle area for one to two hours every other night for 12 weeks. The evaluation comprised grading by clinicians, measuring the wrinkle index with a facial analyzer, and measuring the dermal thickness of the under-eye area with ultrasonography. Any adverse events and discomfort were addressed during the study. The application of Mg MN patches on under-eye areas showed improvements in under-eye grading scale, wrinkle index, and dermal thickness after 12 weeks. The mean grading scale significantly improved after eight weeks of application (p < 0.01). The wrinkle index showed significant improvement after 12 weeks on the right under-eye area (p < 0.05). The dermal thickness of the under-eye area tended to increase, but no statistically significant changes were observed. Non-absorbable Mg MN patches can be used for under-eye wrinkles with minimal discomfort. This article is protected by copyright. All rights reserved.
