Fig 3

The stratum corneum water content was measured every week for 6 weeks as described in the Materials and Methods. The values are expressed as the means ± the SEMs of five animals. ANOVA analysis: F2, 12 = 4.6, P < 0.05 at 5 weeks and F2, 12 = 25.2, P < 0.001 at 6 weeks. The asterisks indicate significant differences (*P < 0.05, **P < 0.01) compared with the AA (-) group by Tukey’s HSD post hoc comparisons. AA, ascorbic acid; AJ, acerola juice.
