In terms of treating pigmentary disorders and other skin conditions such as scars, several studies have shown the effectiveness of picosecond lasers in treating these conditions compared to other lasers.

One study evaluated the efficacy and safety of the picosecond 755-nm Alexandrite laser versus the 1064-nm Q-switched Nd:YAG laser in treating melasma in Asians. The test was conducted on 12 patients who received four treatments in a split-face fashion, separated by 1 month. Each patient received the 755-nm picosecond laser on the right side of their face and the 1064-nm Q-switched Nd:YAG laser on the other side.

At the 3-month follow-up, the clearance rate was higher on the side treated with the 755-nm picosecond laser compared to the 1064-nm Q-switched Nd:YAG laser. It was observed that the 755-nm Alexandrite laser resulted in faster and better clearance of melasma compared to the 1064-nm Q-switched Nd:YAG laser [6].

Another study evaluating various novel oral, injectable, and topical treatments also investigated laser and light treatments for melasma. It found that picosecond lasers showed promising results in the test subjects.

In addition to studies testing picosecond lasers for pigmentary disorders, some studies have shown promising results in the treatment of acne scars. One study showed promising clinical results with a 755-nm picosecond laser for the treatment of acne scars. Treatment of facial acne scars with a diffractive mirror array and a 755-nm picosecond laser showed improvements in appearance and texture after 3 months [7].
