Abstract

In this study, the skin-improving effect was investigated through the oral intake of DuOligo (51.67% lactulose and 15.8% galactooligosaccharides). Thirty seven healthy women (40 ∼ 60 in ages) were divided into placebo group (dextrin) and treatment group (DuOligo group), and each group was given a sample for oral intake for 8 weeks. After that, corneometer value, transepidermal water loss (TEWL), melanin index, erythema index, and wrinkle index were measured. As a result, moisture content of DuOligo group increased 38.22% than control group after 8 weeks significantly (p < 0.01). The TEWL of control group decreased by 3.39 g/h/m2 after 8 weeks but the TEWL of DuOligo group decreased by 5.32 g/h/m2 after 8 weeks. The melanin index of the control group was significantly increased with times, but the melanin index of the DuOligo group did not show any significant difference with times. The total wrinkles, length of total wrinkles, number of wrinkles, and depth of wrinkles significantly decreased (p < 0.05) compared to the control group. These results suggested that the applicability of DuOligo as a skin improving functional material was confirmed.
