A Korean study included 30 patients with hypertrophic scars treated with a combination of 3 different therapeutic modalities: 10600-nm ablative carbon dioxide laser (AFL), copper bromide laser (CBL), and intralesional TAC. At the end of the study, CBL achieved better outcomes for vascularity and pigmentation. AFL and AFL plus TAC were especially effective with regard to thickness and pliability. AFL produced epidermal resurfacing due to collagen remodeling. CBL plus TAC did not aggravate vascularity and pigmentation, suggesting that CBL may compensate for the erythema resulting from TAC. In conclusion, the combination of CBL, AFL, and intralesional TAC may provide a new treatment option for hypertrophic scars. [91]
