Keloids are an individual reaction of skin to damages and are characterized by the overgrowth of the connective and collagen tissue and the appearance of a multitude of blood vessels. Keloids behave as benign tumorous tissue where the skin is injured, with an unpredictable proportion of growth, sense of pain and unpleasantness. Successful methods used to remove, heal and treat keloids are:
Intralesional injection of corticosteroids
This is a painless procedure during which the corticosteroid preparations are injected in the keloid scar itself. Injections of triamcinolone-acetonide which stops the further growth of keloids are applied, which reduces the further growth of keloids by reducing the further synthesis of collagen. The corticosteroid preparation is applied once a month, for a few months, until the maximum results are achieved. The latest treatments include the injection of interferon-alpha, which also reduces the collagen production.
Vbeam Pulse Dye Laser is a novelty in the keloid therapy with excellent end results. Laser beam of a certain wavelength leads to the closure and destruction of blood vessels inside the keloids. This stops the further creation of collagen in the keloid and causes it’s spontaneous dissolvement. The red color of the keloid scar, the pain and sensitivity to touch disappear. With the VBeam laser application there is a remodeling of the collagen in the dermis, and also flattening and softening of keloids. Laser treatment is used in fresh acne scars which stimulates tissue regeneration and eliminates redness. Laser treatments are applied in a one month interval and the number of treatments is individual and depends on the size and age of the keloid. Also, excellent results are achieved by a combination of laser treatment and intralesional injection of corticosteroids with have a strong effect of stopping the overgrowth of connective tissue.
Surgical removal of keloids
Surgical removal of keloids is applied in keloids which are of a large surface and so the before mentioned methods don’t produce aesthetically pleasing results. Surgical intervention carries with it a high risk of recurrence of keloids of even larger proportions in the treated area. This is the reason why after the intervention a further treatment of scars is necessary after the stitches are removed.
