Study Type: Interventional
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.
