Effective Picosecond Nd:YAG laser on seborrheic dermatitis and its mechanism

Background The Picosecond Nd:YAG laser has advantages in skin rejuvenation, which has little damage to surrounding tissues due to the ultra‐short pulse width. We perform clinical application of Picosecond Nd:YAG laser's tender skin mode, which could improve the seborrheic dermatitis. Materials and Methods Sixty‐three subjects with facial seborrheic dermatitis are randomized to be control and observation groups. Records regarding skin subjective improvement, skin barrier function‐related data, skin microbial status, and dermoscopy detection of the two patient groups before and after treatments are investigated. Results Improvements of erythema and scales in observation group are significant compared with controls (p
