Effect of 6-shogaol on HDF viability. a 6-Shogaol was non-toxic to HDFs at concentrations of 5, 10, 20, and 40 μM. b Cell viability of HDFs after UVA irradiation increased upon 6-shogaol treatment in a dose-dependent manner up to 20 μM. The data represents the mean ± S.D. of the relative cell viability in each sample from triplicate experiments. Student’s t test was conducted to determine statistical significance. *p < 0.05 compared with UVA-irradiated cells without 6-shogaol treatment; #p < 0.05 compared with negative controls that were not treated 6-shogaol or UVA irradiation
