Currently, there is no gold standard for the treatment of enlarged facial pores. In this report, we describe a patient with enlarged nasal pores which were treated with a combination of a non-ablative 1450-nm diode laser, a Q-switched and quasi long-pulsed 1064-nm Nd:YAG laser, and an ablative 10 600-nm carbon dioxide fractional laser system. Four months after the final treatment, the condition of the patient's pores had markedly improved, and the patient was satisfied with the results.

This is a case report of a 27-year-old Korean woman with Fitzpatrick skin type IV presenting with refractory arcuate hyperpigmentation, which developed after non-ablative 1450-nm diode laser therapy. The refractory arcuate hyperpigmentation was unresponsive to the use of Q-switched lasers, vitamin C iontophoresis, and a bleaching agent, but was responsive to fractional photothermolysis system treatment.
