In this study, 20 middle-aged women aged from 35 to 55 were studied from October 12, 2020 to November 15, 2020 to find out the effects of improvement of facial skin of Jinyeosoo Clean Mist. Among the 20 participants, 10 were divided into experimental group and 10 control group. The Janus facial skin scope system (PSI Co.) used on the skin to measure pore, wrinkles, elasticity, UV pigmentation, and skin tone observed depending the difference in light sources. The facial examination took place 10 minutes after cleansing to stabilize and a total of 4 examinations were carried out after every week of using Jinyeosoo Clean Mist for 4 weeks. For statistical processing, SPSS statistics program 21.0 was utilized to compare the mean averages of pre-experimental and post-experimental data from the above two groups - the experimental group that used Jinyeosoo Clean Mist (hydrogen ion mist) 1 and 2 and the control group that did not use the subject products - and the corresponding sample t-test was used. As a result of the analysis, the group that used Jinyeosoo Clean Mist showed difference in pores (t=3.280, p<.05), wrinkles (t=4.353, p<.01) and elasticity (t=3.003, p<.05), skin tone(t=3.280, p<.01) under the statistical significance level.
