ABSTRACT
This article explored the effect on improvement of skin on the back of hands, focused on women in their 40s, 50s and 60s who begin to suffer from aging, and conducted a 12-weeks dietary experiment to 10 persons in each group, by categorizing into complex diet group of collagen+vinegar(C+V), single diet group of collagen(C), single diet group of vinegar(V) and control group(Cont). The results were as follows; Oil on the back of her hands of C+V group increased 1.6, 6.0 times that of C or V group, respectively. Melanin on the back of her hands of C+V group decreased 2.2, 4.3 times that of C or V group, respectively. Erythema on the back of her hands of C+V group decreased 3.1, 4.1 times that of C or V group, respectively. Callus on the back of her hands of C+V group decreased 4.5, 2.2 times that of C or V group, respectively. Furthermore, as for skin color on the back of hands, C+V group took a turn for the better than other groups. As for wrinkle on the back of hands, C group and C+V group took a turn for the better, but, C+V group was smoother than other groups. As confirmed by the above results, complex diet of collagen+vinegar had a greater effect on improvement of skin on the back of hands of the women in their 40s, 50s and 60s, comparing with single diet of collagen or vinegar.
