Plain-language summary
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.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
