Effect of Cold Air Cooling on the Incidence of Post Inflammatory Hyperpigmentation Following Laser Treatment
- Conditions
- NevusHyperpigmentation
- Interventions
- Device: Cold air cooling
- Registration Number
- NCT00287001
- Lead Sponsor
- Mahidol University
- Brief Summary
- To investigate the benefit of epidermal cooling on the incidence of post inflammatory hyperpigmentation after laser irradiation
- Detailed Description
* 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.
