Figure 2: Water content of the stratum corneum of UVA-irradiated mice after oral administration of SP and CP over time (A), and after 25 days (B). Symbols and bars represent mean and standard deviation (n=3), respectively. Closed circles, Normal (no UVA irradiation, distilled water); open circles, Control (22.3 J/cm2 UVA, distilled water); closed squares, SP (22.3 J/cm2 UVA, SP); closed triangles, CP (22.3 J/cm2 UVA, CP). *p < 0.05, **p < 0.01 vs. control group (Dunnett’s post-hoc test).
