Efficacy of a Microcurrent-Assisted Microneedling Beauty Device for Improving Facial Pores

This study aimed to evaluate the effects of a microcurrent microneedle-based beauty device combined with an ampoule on pore improvement in adult skin. A total of 20 participants aged 20-49 years with moderate to severe facial pores were enrolled and instructed to use the device twice weekly for 6 weeks, along with daily application of an identical ampoule. Pore conditions were assessed using a digital imaging system (Visio Face®1000D) at baseline, 3 weeks, and 6 weeks. In addition, a sensory evaluation was conducted to examine subjective user perceptions. The results showed that fine pores significantly decreased at 3 weeks and remained stable through 6 weeks. In contrast, large pores demonstrated a continuous reduction over time, indicating a progressive improvement pattern. Sensory evaluation results revealed significant improvements in perceived pore size, pore count, and skin firmness, along with low levels of irritation and heating sensation. High usability and purchase intention were also reported. In conclusion, the combined use of a microcurrent microneedle beauty device and an ampoule is an effective and safe non-invasive approach for reducing pore size and number. These findings suggest its potential as a practical home-care solution for pore management and provide foundational evidence for the clinical applicability of non-invasive beauty devices.
