Successful Treatment of Nevus of Ota With a 694-nm Q-switched Ruby Laser: A Case Report

Nevus of Ota is a benign dermal melanocytosis characterized by gray-blue facial hyperpigmentation that may cause significant cosmetic concerns and is commonly treated with laser therapy. We present the case of a 39-year-old woman with facial nevus of Ota who underwent treatment with a 694-nm Q-switched ruby laser, achieving marked pigment clearance after two treatment sessions. This case further supports the efficacy and safety of Q-switched ruby laser technology as a therapeutic option for nevus of Ota.
