Clinical images were used to calculate the percentage of dermatitis in treated areas. The arithmetic mean roughness (Ra), the average depth of roughness (Rz) and the mean square roughness (Rq) were used to assess the change of surface roughness. Transepidermal water loss (TEWL), stratum corneum hydration (SCH) and total lipid content (TLC) were used to analyze the skin barrier function.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>After treatment, we found that 27.15% (139\/512) of PWS patients developed dermatitis on the treated areas, and the percentage of dermatitis was closely related to the treatment times and age of the patient. Moreover, these treated areas also exhibited markedly increased skin roughness (Ra, Rz, Rq; <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.05) and impaired barrier function, evidenced by significantly
