The Efficacy and Safety of a Low-Fluence 1064 nm Picosecond ND-YAG Laser Compared with Those of a Low-Fluence Photoacoustic Therapy Pulsed (PTP) Mode 1064 nm Q-Switched ND-YAG Laser for Treatment of Melasma: A Prospective Split-Face Study

Figure 2

A 51-year-old female patient with melasma of Fitzpatrick skin type III. The left side of the face was treated with a PTP mode 1064 nm Q-switched laser (A–C), and the right side was treated with a 1064 nm picosecond ND-YAG laser (D–F). Baseline (week 0), the mMASI scores were 11.55 (A) and 12.30 (D), respectively. On the 5th visit (week 8), the mMASI scores were 3.60 (B) and 3.80 (E). On the follow-up visit (2 months after last treatment), the mMASI scores were 5.00 (C) and 4.80 (F).
