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.

Conditions

• Hyperpigmentation
