Research output: Contribution to journalArticlepeer-review


Sebum is one of the important factors in maintaining the hydration of the stratum corneum by covering the skin surface. However, dilated pores and skin greasiness on the face cause concern in young to middle-aged women. Because the density of hair follicles and sebum output are higher on the center of the face, following a centrolateral decreasing gradient, skin greasiness is generally recognized on the mid forehead, nose, nasolabial fold, and chin, the so-called T-zone of the face. The surface lipid levels of the facial skin in women are higher when young and decrease steeply from the sixth decade. There are two types of conspicuous pores, those with an empty funnel-shaped structure and those with cornified cylindrical plugs corresponding to comedones. The sebum output and the size of follicular orifice are positively correlated. However, the age-related loss of dermal integrity and perifollicular structural support may lead to enlarged pores after middle-age.
