Keloids are firm raised scars that occur after injury to the skin, but have grown beyond the initial wound area. The source of skin injury can vary, and can include acne, ear piericings, or a surgical procedure. Keloids may enlarge over time and can become itchy, tender, or unsightly. Keloids can occur anywhere on the body, but most commonly occur over the chest, back, shoulders and earlobes. They can vary in color and be skin-colored, pink, red or dark brown. Some people are genetically predisposed to get keloids.
We do not completely understand why keloids form. The specifics of the biochemical signaling in wound healing and in cell growth have not yet been fully determined. The tendency to form keloids can run in families.
Liu Dermatology offers a variety of treatment options as there is no one therapy that works well for everyone. Keloids commonly respond to cortisone injections but other therapies including freezing with liquid nitrogen, surgical removal, compression treatment, irradiation and the use of certain lasers are also treatment options. Treatment is quite effective in improving the appearance of the scar and in greatly improving any symptoms of pain or itch. Any discomfort associated with treatment is well tolerated.
