Abstract

本研究では10代から50代の, 248名の日本人女性の顔面を対象とし, 目立つ毛穴の実態調査を行った。その結果, 20代から30代で目立つ毛穴には角栓が存在し, 角栓の組成を分析した結果, タンパク質成分が約7割を占めることが判明した。一方40代以降では角栓が存在せずに開大した状態の目立つ毛穴が存在することが明らかとなった。また毛穴の開口部面積は10代から20代と, 30代から40代で各々急増するという, 2段階の変化を示す一方, 皮脂量との関連性は年齢とともに低下した。これらの結果から, 若年層では毛穴は角栓が詰まることによって目立ち, 年齢とともに毛穴の中に角栓が存在しなくなっても目立つ構造に変わっていくことが推察された。この調査結果から目立つ毛穴に対するケア方法は画一的ではなく, その性状, 年齢に応じて異なるべきであることが示唆された。

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.
