Keloids are skin-covered outgrowths that occur at sites of injury. They are warm, itchy, pink and at times painful. It is estimated that 15 to 20% of the population are keloid prone. In the keloid prone, the chemical signals that regulate fibrocytes may be defective and the deposition of new fibre does not stop when it must. This results in the accumulation of a large heap of fibres covered by epidermis. This growth is visible to us as a keloid.
