Abstract
|
|
|
|
Postinflammatory hyperpigmentation (PIH) is a reactive hypermelanosis of the skin occurring as a result of variable inflammatory processes, such as trauma, and inflammatory dermatosis. Although topical agents are the first-line treatment of PIH, treatment of PIH remains challenging. In this report, we treated a patient with PIH using picosecond-domain Nd:YAG lasers. After five sessions of 1,064-nm picosecond-domain Nd:YAG laser treatment, the patient presented nearly complete improvement, with no remarkable side effects or recurrence for the duration of 6 months. We suggest that 1,064-nm picosecond-domain Nd:YAG laser can be effectively and safely used to treat pigmented lesions in the dermis, particularly PIH, in Asian patients.
