However,keloids are also known to occur spontaneously without a history of trauma to a particular site. The exact cause for this disorder remains elusive, but most likely entailsgenetic and environmental factors [3]. Furthermore, cytokine transforming growth factor (TGF)-b has been involved in the pathogenesis of keloid, and the combination of raised levels of TGF-b and the abnormal response of proliferative scar fibroblasts to this cytokine may result in keloid formation [4, 5]. The incidence of these lesions in darkskinned people is different in different studies and ranges from 4.5 to 16% [6, 7]. Besides, keloids have a higherincidence in dark-skinned individuals, estimated to be 3–20 times compared to light-skinned individuals [8]. Although these scars have a higher incidence and result in significant physical (pain, itching, and deformity) and psychological (a deformed look) problems [9], there is no universally accepted treatment modality that guarantees permanent hypertrophic or keloid scar ablation
