Mice concurrently treated with imiquimod and LED-RL have decreased epidermal thickness compared to mice only treated with imiquimod. Topical imiquimod was applied on days 1–4. Mice were irradiated on days 1–4. Representative images of (A) Control, (B) 1280 J/cm2 RL daily, and (C) 640 J/cm2 RL twice daily groups. (D) Quantified epidermal thickness of control, 1280 J/cm2 RL daily, and 640 J/cm2 RL twice daily treatment groups (n = 6 technical repeats). ANOVA followed by Dunnett’s multiple comparison test was used to assess significance across three groups. * denotes A p-value < 0.05.
