Skin pores are tiny holes in a person’s skin and small openings in the skin that release oils and sweat. They’re also connected to your hair follicles. If pores are increased, it may lead to acne, increased sebum production, which causes oily skin, sun damage, noncomedogenic makeup. If a person has large skin pores, they may not be able to change this. It may be possible to reduce the appearance by keeping them unclogged. Maintaining clean, healthy skin pores is important for maintaining healthy (and healthy looking) skin. Dirt and oil on your face collect around your pores like leaves and debris collect around a storm drain. When those pores get clogged, it creates a pile-up of oil and dead skin cells in the follicle. Soon, bacteria make their way to the blockage, and the growth in bacteria causes inflammation.
