A keloid is a harmless growth of fibrous tissue at the site of a healing scar caused by overproduction of collagen. Keloids are most common on the breastbone, upper back, and shoulder but can occur anywhere on the body.
Some people, especially those with dark skin, are more prone to developing keloids.
Signs and symptoms include:
Firm, raised, hard scars.
Colour that varies from slightly pink to very dark.
Tenderness or itching.
Continued growth and claw like projections.
Doctors do not understand exactly why keloids form in certain people or situations and not in others. Changes in the cellular signals that control growth and proliferation may be related to the process of keloid formation, but these changes have not yet been characterized scientifically.
Keloids are less common in children and the elderly. Although people with darker skin are more likely to develop them, keloids can occur in men and women of all skin types. In some cases, the tendency to form keloids seems to run in families. Keloids develop most often on the chest, back, shoulders, and earlobes. They rarely develop on the face (with the exception of the jawline).
Keloids are treated with monthly intralesional corticosteroids as well as weekly Laser Genesis treatments with the NdYag laser to reduce the redness. A series of 6 to 8 treatments are needed for best results. Botox intralesionally is experimental. At Skin Renewal we have has success with Botox combined with intralesional steroids and Laser Genesis treatments.
