Pores are the openings of the hair follicles in the skin. Because the sebaceous glands open in the walls of the hair follicles, the pores are also the ducts for sebum discharge. The sebaceous glands on the face are more active and need larger openings to excrete the oil they secrete, so the pores on the face are usually much more visible than other parts of the body, and the pores on the nose and the cheeks next to the nose are larger than other areas.
