Official Title: 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 Ma

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

Detailed Summary:

  • 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.

Current Primary Outcome: Incidence of post inflammatory hyperpigmentation [ Time Frame: 2 weeks ]

Original Primary Outcome: Incidence of post inflammatory hyperpigmentation

Current Secondary Outcome: Side effects of cold air cooling and clearing rate of pigmented lesion [ Time Frame: 12 weeks ]

Original Secondary Outcome:

  • - Side effects of cold air cooling
  • - Clearing rate of pigmented lesion
