The compared analysis of effects on skin moisture, oiliness, roughness, wrinkles, and pigments of middle-age women, along with test subject’s subjective assessments, and skin irritation symptoms were used in this study. In the first part of the study, a survey was done to find out the relationship between the internal and external causes that have effects on skin conditions. The analysis of facial skin conditions (moisture, oiliness, roughness, wrinkles, and pigmentation) from 30% GA liquid form group and 30% GA cream form group are as follows. As a result, it was found that, in moisturization, oiliness, wrinkles, and pigmentation, 30% GA cream form is more effective with increasing number of treatments than to 30% GA liquid form. As for change in roughness, it was found that 30% GA liquid form is more effective with increasing number of treatments than 30% GA cream form. According to the results of the study, it was evident that 30% GA cream form was found more effective in improving skin conditions, but in terms of anti-aging, they both showed positive results. Therefore, this study concludes that GA cream form is less irritating and effective in improving skin conditions for middle-age women in 30s and 40s, and believes it will have importance in making program proposal for the skin care industry.
