Side Effects of Q-Switched Ruby Laser for the Treatment of Lentigines in Light and Dark Skin Types
Efficacy and Side Effects of Q-Switched Ruby Laser Treatment of Solar Lentigines in Two Different Fitzpatrick Skin Types II and IV

The purpose of this study is a comparison of efficacy and side effects of Q-switched Ruby laser treatment for solar lentigines in two different skin types II and IV.

It has been widely accepted that dark colored individuals are prone to develop laser induced side effects especially post inflammatory hyperpigmentation(PIH) and it could be a limiting issue in selecting dark colored individuals.

We designed this study to evaluate the difference of efficacy and side effects in light and dark skinned individuals.
