미용기기가 피부개선에 미치는 효과에 대한 메타분석

Abstract

This study attempted to investigate the effectiveness of cosmetology device-based skin improvement variables through Meta-analysis based on the previous studies from 2000 to 2018, and the results found the following: First, the overall skin improvement effects of cosmetology devices were large with 1.391. Second, in terms of the effects of sub-variables on skin improvement, ‘inner variable group’ was the highest with 1.591, followed by ‘skin tone group (1.441)’ and ‘outer variable group (1.052)’. Third, in terms of the effects of the inner variable group on skin improvement, ‘moisture’ was the highest with 2.093, followed by ‘pH (1.751)’, ‘temperature (1.131)’ and ‘sebum (1.112)’. In terms of outer variables, ‘elasticity’ was the highest with 1.880, followed by ‘coarseness (1.507)’, ‘wrinkles (1.351)’, ‘pores (1.347)’ and ‘dead skin cells (0.883)’. In skin tone, the effects were large in all sub-variables but ‘brightness (0.774)’. This study attempted to analyze diverse studies on skin improvement using cosmetology devices through Meta-analysis and suggest comprehensive and universal data which are applicable to the beauty industry. It is anticipated that this study would examine the prospect and role of digital technology-based skincare using cosmetology devices in the era of a smart beauty industry.
