What are Pores – What Causes Large Pores
Pores are openings in the skin (a.k.a hair follicles) which allow sweat and natural oils to be released from your body. Oils released from these glands (sebum) help moisturize the skin naturally.
While people with dry skin tend to have small pores, people with oily skin tend to have large, visible pores – which causes an overproduction of oil.
