Pores that look visibly dilated could result from oily skin, the presence of blackheads, excessive exposure to the sun, and ageing. When the enlarged pores are clogged with sebum and impurities, they tend to stretch out, making them more noticeable to the eye.
Enlarged pores are prevalent during puberty as the sebaceous glands tend to produce more sebum. Loss of skin elasticity due to ageing may also enlarge pores.
