Histological assessment of photoaging. a Increased epidermal thickness, β-galactosidase expression, and decreased dermis thickness in the ultraviolet B (UVB) group. The appearance of skin photoaging improved in the UVB + 150 μg/week and UVB + 300 μg/week groups. Black arrows indicate dermis thickness. Scale bars = 150 μm. b Epidermal thickness statistics. c Dermis thickness statistics. d Skin β-galactosidase expression statistics. *P < 0.05 indicated a significant difference; n.s., no significant difference between groups
