简要总结
- To investigate the benefit of epidermal cooling on the incidence of post inflammatory hyperpigmentation after laser irradiation
详细描述
- 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.
