We conducted a research survey regarding the occurrence of prominent pores with respect to age by measuring pores on the faces of 248 Japanese women. Enlarged, prominent facial pores of women in their 20's and 30's showed they were full of follicular casts. A large proportion of these follicular casts were filled with protein. However, as the women aged, their pores were gradually replaced by pores that were not full of follicular casts. The size of facial pores showed a two-staged pattern of increase with age. Furthermore, the relationship between the size of the facial pore and the amount of sebum secretion gradually decreased with age. We speculate that facial pores become highly prominent when women are young because they become filled with follicular casts, and that these pores may remain visible, even when not filled with follicular casts, as women age. Different types of care are needed for different types of facial pores that occur with age.
