Liquiritin reduces UVB-induced oxidative stress in mice. Activity of SOD and levels of MDA in (A) serum and (B) skin tissue samples were evaluated. (C) Levels of H2O2 and O2. in the skin were assessed. Data are presented as the mean ± standard error of the mean (n=10). **P<0.01 and ***P<0.001, compared with the Con group. +P<0.05, ++P<0.01 and +++P<0.001, compared with the UVB-only group. UVB, ultraviolet B; Con, control; SOD, superoxide dismutase; MDA, malondialdehyde.
