The beauty industry is more and more expanding due to the continuously increased interest in appearance and consumer purchases. Especially for home beauty devices, their interests hve been increased since the outbreak of COVID-19. Over the past 20 years, various studies have been conducted on beauty device, but Galvanic device has not been enough. In this study, 24 adult women, aged 43 to 59, were conducted a survey and skin analysis before and after using galvanic LED skin device for four weeks. Skin analysis was carried out by Antrea 3D(Miravex Ltd., Ireland), F-ray(BEYOUNG Co., Korea), and DUB SkinScanner(tpm Co., Germany). According to the survey, few people experienced skin-care shops or beauty devices, but many people responded positive after using the device. For the results of eye wrinkles, the average depth of wrinkles was significantly reduced(improved) in the top 25% group of subjects, and the wrinkles around the mouth were also significantly reduced(improved). Before using the device, the lifting around the eyes increased significantly from the middle 50% of the skin's sagging angle. Although the cheek area decreased (improved), the skin density increased(improved) significantly in the lower 75% of subjects with low skin density before use. The pore volumn was significantly reduced(improved) from 25% of the average pore volume before use. Pore area, density, count, depth and filling were significantly reduced(improved) from the top 75% of the skin conditions before use. For pore binding, the pore roughness value before use of the device was significantly reduced(improved) in all subjects. From the above results, it can be noted that the wrinkles, lifting, skin density and pores of galvanic LED skin beauty device have been improved. In addition, subjects with poor skin conditions showed greater improvement than those with good skin conditions.
