Open pores can refer to large pores on the skin. Large pores are noticeable to the naked eye. The size is common in both oily and combination skin because of excess oil production from sebaceous glands. Blackheads, a common skin complaint, form into plugs at the opening of your pores.
The term “open pores” can lead to misconceptions about the size of your pores. The size ultimately depends on the activity level of the sebaceous glands, and not on your beauty habits. Also, while blackheads might make your pores look bigger, the pores won’t shrink if you remove the plugs.
