Pores are natural openings in the skin that release oil and sweat. When pores appear enlarged, they are often more noticeable on the nose and cheeks. Several factors contribute to this appearance, including increased sebum production, genetic predisposition to larger pores, and a loss of skin elasticity over time. Sun exposure and thickened skin from buildup can also make pores more visible. The appearance of enlarged pores is purely cosmetic and does not indicate a skin problem.
