Pores are tiny openings on the surface of the skin that allow sweat and oil to escape. They are essential for regulating body temperature and keeping the skin moisturized. Each pore is connected to a sebaceous gland, which produces sebum, a natural oil that helps protect and hydrate the skin. Pores can vary in size and appearance, influenced by factors such as genetics, age, and skin type. Acne and other skin conditions can cause pores to become clogged, leading to blemishes. Proper skincare, including cleansing and exfoliating, can help maintain healthy pores and improve overall skin appearance.
