Enlarged pores are an extremely common skincare concern for many patients, occurring as a result of excess oil production within the skin. Sometimes, your sebaceous glands go into overdrive, producing excess oil that then clogs your pores as it combines with dead skin cells and other dirt and debris on the surface of your skin.
Clogged pores consequently become wider and more visible, a process which can also lead to the formation of blackheads. Sun exposure and genetics also may be a factor. Large pores can worsen as we age due to weakened skin laxity.
