Effect of fermented milk and EPS on skin erythema and cell proliferation in hairless mice following UV-B exposure. Δa* (redness) value (a* value in UV-B irradiated skin − a* value in a non-irradiated site) (a); epidermal thickness (b); and Ki-67 positive number (c) were determined after a single dose of UV-B irradiation. The values are shown as means + SEM (n = 8). * p < 0.05 (vs. the control group). # p < 0.05 (vs. before UV-B irradiation).
