A pore is a tiny opening on the surface of the skin that allows sweat and oil to escape. These openings are essential for regulating body temperature and maintaining skin health. Each pore is connected to a sebaceous gland, which produces sebum, an oily substance that helps keep the skin moisturized. Pores can become clogged with dirt, oil, and dead skin cells, leading to issues like acne or blackheads. Proper skincare, including cleansing and exfoliating, can help keep pores clear and minimize their appearance. Maintaining healthy pores is important for overall skin health and appearance.
