Pores are tiny openings in the skin that release perspiration and oil (sebum) to cool and condition your body. There are up to half a million pores per square centimetre on the skin’s surface. Open pores typically develop as a result of blocked pores, insufficient free water levels within the skin and an accumulation of dead cell material. They appear as small pits giving the skin a dimpled appearance similar to an orange peel. Whilst the nose, forehead and chin areas (the T-Zone) are the most common areas for open pores, they can occur anywhere on the body on all skin types and conditions.
Open pores can be caused by lots of different factors including genetics, seborrhoea (excessive, thickened oil flow), acne and extractions (squeezing pimples).
