Retrospective study compares 730-nm picosecond laser and 532-nm Nd:YAG laser for facial pigmentation, suggesting higher efficacy and safety for the picosecond laser.
Compared with 532-nm Q-switched Nd:YAG laser, 730-nm picosecond laser therapy is more effective and safer for treating facial pigmentation disorders. It achieves greater clinical improvement, enhanced patient satisfaction, and superior skin quality outcomes with fewer adverse effects, supporting its preferential use in clinical practice.
