This studying was 9 female subjects in their 20s and living in urban areas participated in the experiment. The experiment was conducted for 8 weeks from May 16, 2010 thru July 4, 2010. In terms of measuring the skin condition, the research used the skin physiological measurement equipment MPA5.
The data collected from the study was statistically evaluated with SPSS 19.0 and all the empirical analysis were verified under 5% significance level.
Skin condition after the experiment for subjects in the experiments group, the moisture level increased(F=23.397, p<.OOl) and Melanin level decreased(F=28.753, p<.OOl) in overall with the number of experiments, and, compared to the control group, the experimental group showed significant higher level of moisture (p < .001). In terms of pH change, there was significant change after each experiment (F = 29.027, p < .001).
Results on Erythema indicated that there is a significant difference as the number of experiments increased (F = 7.320, p < .01). There was no significant statistical difference for skin moisture evaporation, but the level of moisture evaporation decreased in general after the experiments making the skin feel more moisturized. The statistic results on elasticity indicated the change for the experimental group was significant compared to that of the control group (F = 6.609, p < .01). To sum up these results, the use of natural cosmetics containing the tendency to gradually improve the skin condition showing its effectiveness for skin care especially in the area of moisture level, pH level, Melanin, and elasticity.
