Treatment of refractory arcuate hyperpigmentation using a fractional  photothermolysis system.
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.
