Effects of corn silk (CS) extract on UVB-induced wrinkle formation in the dorsal skin of SKH-1 mice at the end of the study (week 19). Photographs of the replica, replica analysis, and the backs of the mice (A), Hematoxylin and eosin-stained sections (original magnification 100×) (B), epidermal thickness (C), skinfold thickness (D), mean of skin wrinkle depression volume (E), mean depression area (F), maximum depth (G), and wrinkle length (H) are presented for normal group (NOR), UVB-irradiated group (UVB), UVB-irradiated and low CS- (2 g/kg/day) treated group (CSL), UVB-irradiated and high (4 g/kg/day) CS-treated group (CSH). Values are mean ± SD. The results were analyzed by one-way analysis of variance (ANOVA) followed by Duncan’s post-hoc test. Means with different lowercase letters (a, b, c, d) represent statistically significant differences (p < 0.05). Bars with the same letters are not significantly different.
