Morphometric parameters in the papillary dermis. (A) Scatter plot of the thickness of the papillary dermis as a function of age. (B) Thickness of the papillary dermis in a 1-month-old individual (mean of 44.84 μm). (C) Thickness of the papillary dermis in a 79-year-old subject (mean of 137.1 μm). (D) Scatter plot of the area occupied by collagen (density of collagen bundles) in the papillary dermis as a function of age. (E) Area occupied by collagen in the papillary dermis in a 40-year-old subject (mean of 73.63% density). (F) Area occupied by collagen in the papillary dermis of a 95-year-old individual (mean of 43.27% density). (G) Scatter plot of the collagen thickness in the papillary dermis on the basis of age. (H) Thickness of collagen in the papillary dermis in a 2-year-old subject (mean of 1.37 μm). (I) Thickness of the collagen of the papillary dermis in a 90-year-old subject (mean of 0.52 μm).
