Histological analysis of collagen deposition and MMP levels in mouse dorsal skin. (A) Masson staining of mouse dorsal skin tissues, showing collagen distribution (n = 7, scale bar = 100 μm). a: normal group; b: model group; c: positive control group; d: low-dose LELNs group; e: medium-dose LELNs group; f: high-dose LELNs group. (B) Quantization of collagen fiber area ratio (**P < 0.01 vs. M, #P < 0.05 vs. C, n = 7). (C-E) Levels of COI-I (C), MMP-1 (D), and MMP-3 (E) in dorsal skin homogenates. (**P < 0.01 vs. M, #P < 0.05, ##P < 0.01 vs. C, n = 7).
