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.
