Measurements were taken at 30 places on the inner side of both upper arms each week as part of various drinking tests, using a device that quantifies the measurements as the collagen score. In the first experiment, an immediate increase in the collagen score by 8 points in the first week and a continuous increase of 20 points in the fourth week were observed. In the second experiment, immediate and continuous effects were observed, with increase of 6 and 10 points in the collagen score in the first and fourth weeks, respectively. The third experiment showed that the collagen score in the first and second weeks increased by 4 and 9 points, respectively, and the keratinous moisture content increased by 3 and 8 points, respectively. These findings indicate that ethyl α-D-glucoside intake improves both the resilience and glow of the skin.
