Photoprotective effects on mouse skin. A Representative digital graphs of mouse dorsal skin three days after pre-protection and subsequent UV exposure. ZIF-8 group showed less erythema compared to no protection or glycerol groups. B Microscope photographs of skin with H&E staining. C Microscope photographs of skin with CPD immunohistochemistry. D, E Quantitative analysis of (D) epidermal thickness and E CPD positive cells in the skin after pre-protection and subsequent UV exposure. ZIF-8 inhibited epidermal hyperplasia and CPD formation
