research 604 Comparison of 1064-nm Nd:YAG picosecond lasers using fractional micro-lens array vs. ablative fractional 2940-nm Er:YAG lasers for the treatment of atrophic acne scar in Asians: A 20-week prospective, randomized, split-face, controlled trial
In this study, Nd:YAG picosecond lasers using fractional micro-lens array were found to have a comparable effect to ablative fractional Er:YAG lasers in treating atrophic acne scars, with better safety profiles but slightly less patient satisfaction.
