Song H, et al. - Whether the effect of intralesional triamcinolone acetonide injection during the early stage of scarring differs from the static stage was investigated in this analysis. Participants in the study were 108 subjects with pathological scars. According to the findings obtained, the treatment efficacy was better when applied during the static stage of pathological scarring rather than the early stage, which could be due to macrophages and their released cytokines. New clinical evidence for optimizing drug therapy of pathological scars was provided in this investigation.
