Pores are those tiny dots you see on the surface of your skin and are actually the openings of hair follicles. The size of the pore is attributed to the size of the oil gland and hair follicle that it contains.
People who have skin that is naturally thick and oily tend to have larger pores. As people get older, too, sun damage and decreased skin elasticity can cause pores to dilate. The skin thickens, causing tiny cells to collect around the edge of the pores and make them look larger.
Blackheads are also a big contributor to large pores. When the pore becomes clogged by dirt and bacteria, oil within the pore begins to accumulate, causing the pore's diameter to expand.
Untreated open pores will contribute to further outbreaks of spots, and possibly even acne.
Causes of pores:
Acne skin prone
Poor skincare routine
