Scar formation of laser skin lesions after cold atmospheric pressure plasma (CAP) treatment: A clinical long term observation

Abstract CAP treatment is likely to be of benefit in wound healing. In a clinical study, 20 laser lesions in five individuals have been treated with argon plasma 10, 30 or three times for 10 s, with untreated as control. The scar formation was followed for 10 days, six and 12 months. In early stages of wound healing, plasma treatment seems to support the inflammation needed for tissue recovery. In later stages, plasma treatment shows better results in terms of avoiding post-traumatic skin disorders. Plasma treatment shows superior aesthetics during scar formation. No precancerous skin features occurred up to 12 months.
