Effect of Cold Air Cooling on the Incidence of Post Inflammatory Hyperpigmentation Following Laser Treatment
Effect of Cold Air Cooling on the Incidence of Post Inflammatory Hyperpigmentation Following a Q-Switched Nd:YAG Laser Treatment of Acquired Bilateral Nevus of Ota-Like Macules

- To investigate the benefit of epidermal cooling on the incidence of post inflammatory hyperpigmentation after laser irradiation

  • 70% incidence of post inflammatory hyperpigmentation has been reported following a Q-switched nd:YAG laser treatment of acquired bilateral nevus of Ota-like macules.
  • We assumed that epidermal cooling may minimize the non-specific injury to the epidermis caused during laser irradiation, leading to the decreased incidence of post inflammatory hyperpigmentation.
