Pores are tiny orifices on the skin from which sweat and oil flow. They can become bigger due to external stress, excess oil flow or insufficient care, often on the sides of the nose and the T-zone. Impurities then have the ability to lodge themselves in the pores and build up until a blackhead appears. Everyone’s pores are more or less dilated and therefore visible, but this issue is more common in men than women, and in oily skin. An easy way to determine if your pores are enlarged is to compare the area of concern with another area of the face. Pores commonly become enlarged in the T-zone (forehead, nose and chin) where there is more oil flow.
