In recent years, with the maturity of laser technology, laser therapy is one of the popular options for the treatment of pigment diseases. The absorption spectrum of melanin ranges from 300 to 1,000 nm. In past studies, the 532 nm Q-switched Nd:YAG laser is effective for the treatment of superficial melanin. But there are still some side effects in laser treatment, such as post-inflammation pigmentation (PIH), depigmentation, skin redness, etc., and PIH is particularly likely to occur on darker skin. However, there is still no good evidence as to what factors or laser treatments can cause PIH. Therefore, in this study, we will use ApolloVue® S100 Image System (ApolloVue® S100 Image System is a medical device class II) to scan before and after skin of laser treatment to observe the changes in the skin condition. By observing and analyzing these changes, as a evaluation of predictors or prognostic factors after laser treatment and whether PIH will occur.
