ABSTRACT: Many studies on aging have focused on evaluating
differences between older and younger people, but only a few have focused on
differences in skin properties among subjects from the same age group according
to their skin aging status. In this study, we evaluated the facial skin
condition and life style factors in 110 Korean women aged 25 to 35 in an
attempt to evaluate factors which may affect the skin aging status in the
initial aging phase. The facial skin condition of 110 healthy Korean women was
assessed over two successive 6-month periods, summer and winter. Using clinical
assessments including aging, wrinkles and skin’s elasticity values, the
subjects were divided into 7 groups. Then, various facial skin conditions and
life style factors were examined between a severe aging group and mild aging
group. In the severe aging group, the mean value pH was lower and the mean
value of water content was slightly lower than that of women in the mild aging
group. Also, the seasonal site variation in water content and sebum secretion
level were significantly higher in the severe aging group than in the mild
aging group. Topical sunscreen using percentage was not significantly different
between the two groups. However, the number of cosmetic subject use was
slightly higher in the mild aging group than in the severe aging group. The
study suggested that there were several differences in skin characteristics
between women in the severe aging group and in the mild aging group at the
initial aging phase. Seasonal site variation between cheek and forehead was the
most dominant differences. We also considered that life style factors such as
cosmetic use could affect skin aging status.
