“…[2][3][4][5][6] Picosecond-domain lasers are reportedly more efficacious in removing pigment in the form of tattoos than nanosecond-domain lasers. [7][8][9] Moreover, the risk of side effects is lower in picosecond-domain lasers, compared with nanosecond-domain lasers.…”

Acquired bilateral nevus of Ota-like macules (ABNOM) is a common dermal lesion of melanotic hyperpigmentation in Asians. To treat ABNOM, various nanosecond-domain lasers, including Q-switched 694-nm ruby, 1,064-nm neodymium:yttrium-aluminum-garnet (Nd:YAG), and 755-nm alexandrite lasers, have been used. In this report, we treated a patient with ABNOM using 1,064-nm nanosecond-domain and picosecond-domain Nd:YAG lasers. At 3 months after one session of 1,064-nm nanosecond-domain Nd:YAG laser treatment, ABNOM lesions were partially improved. Then, an additional session of 1,064-nm picosecond-domain Nd:YAG laser treatment was delivered to ABNOM lesions. The patient presented nearly complete improvement thereof with no remarkable side effects or recurrence over the duration of 18 months. Picosecond-domain lasers were deemed to generate faster photothermal reactions, more extensive photoacoustic effects, and less injury to adjacent structures than nanosecond-domain lasers. We suggest that 1,064-nm picosecond-domain Nd:YAG laser can be effectively and safely used for treating pigmented lesions in the dermis, particularly ABNOM, in Asian patients.
