Background: Postinflammatory hyperpigmentation (PIH) is a common sequela seen in the Indian population following affliction by acne. It is psychologically extremely disturbing for the patients and can severely affect the quality of life. Very few therapeutic modalities have proved to be really efficacious in this condition. Aims: The aim was to review our experience with 1,064-nm Q-switched neodymium-doped yttrium aluminum garnet (QSNY) laser in the treatment of PIH. Materials and Methods: Seventy-eight patients with postacne hyperpigmentation were included in the study. They were treated with six sessions at two weekly intervals using a 1,064-nm QSNY laser. Patient and physician scores were assessed at 1 month and 3 months after the last treatment. Clinical photographs also were reviewed to determine the efficacy. Adverse effects were noted. Results: Seventy percent of the patients reported significant improvement in hyperpigmentation as compared to the baseline. The majority of the adverse events were limited to mild, brief erythema. Conclusion: The 1,064-nm QSNY laser is an effective modality for the treatment of PIH caused by acne.
