The morphological changes of facial skin surface with aging were investigated with special reference to an alteration of the pore. Replica of the skin at upper cheek, middle cheek, lower cheek and chin were obtained from a total of 98 Japanese females ranging in age 18 to 78 years old. The image of replica was classified into two elements, 1) large and hollow pore and 2) skin furrows, and then size and length of which were measured by using image analysis software. Lower cheek and chin showed a continuous increase in mean pore size and number of the pore along with aging. While at upper and middle cheek pore discontinuously augmented mean size having a peak around 40 years old and grew in length with aging. The morphological changes of the pore with aging revealed regional difference in the facial skin. Taken together these results, it was suggested that the age-related structural changes surrounding pore was developed and resulted in an appearance of large and hollow pore, but skin elongation by sagging had possible influence on the morphological changes of the pore at upper and middle cheek.
