Large-looking pores are usually a mix of oil production, skin structure, and age. Pores are openings for hair follicles and oil glands, and when they are more noticeable, it does not mean they are abnormal or dirty. In many people, they simply stand out more on the cheeks, nose, and forehead.
One main reason pores look bigger is higher oil production. When more oil flows through a pore, it can stretch the opening and make it easier to see. Skin changes over time also matter. As skin ages or is exposed to a lot of sun, it loses firmness and support, so pore edges do not snap back as well and appear wider.
Genetics also play a role. Some people naturally have larger or more visible pores, regardless of their skincare habits. Past or ongoing acne and skin inflammation can add to this by weakening the pore walls, especially if breakouts are frequent.
You cannot permanently shrink pores, but gentle care and sun protection can help them look less obvious. Avoid picking or harsh products that irritate the skin. If pore size or oiliness is bothering you a lot, a dermatologist can help guide safe treatment options rather than trying strong products on your own.
