Table 1 Distribution of the 2,585 study subjects and their relative age ranges in the four countries where imaging of skin pores was performed

Table 2 Distribution of the 960 subjects claiming to have large skin pores and their relative age ranges in five countries, from which the 30% of subjects with the largest sP arbitrarily selected and analyzed in all age classes
