A split-face, evaluator-blind randomized study on the early effects of Q-switched Nd:YAG laser versus Er:YAG micropeel in light solar lentigines in Asians.

摘要

While there is no perfect therapy for light solar lentigines, a single session of Q-switched Nd:YAG laser and Er:YAG micropeel was shown to reduce pigmentation. The immediate effects (2-week follow-up) were better with the Q-switched Nd:YAG laser but there was no great difference between the two laser types at 1-month follow-up due to the greater degree of post-inflammatory hyperpigmentation following Q-switched Nd:YAG. Both laser types could be applied either singly in turns, or in combination for maximal efficacy in future.
