Post inflammatory hyperpigmentation

It's been a year and 8 months since I had the Fraxel treatment done. I still have PIH on my cheeks, which gets worse noticeably with sun exposure. However, I have found this miracle medication called Transino. It is made by a Japanese company, and when I take it, it get lighter significantly. But, when I stop taking it, my PIH goes back to how it was before. This medication is not supposed to be taken more than 3 month at a time. I am thinking about getting Picosure done on make it even lighter. Any advice would be appreciated.

I had a Fraxel laser treatment done on my face about 3 month ago. About a week after the treatment, scabs fell off, and new skin looked amazing. BUT, a few days later, I started to have HUGE brown spots all over my face, especially under my eyes. It's been 3 month since the treatment, and my post-inflammatory hyper-pigmentation is not getting any better. If I had known that I was going to suffer from this horrible condition, I wouldn't have gone through with this treatment. People ask me all the time what I have done to my face. Some people think I am a victim of domestic violence because I have the hyper-pigmentation around my eyes. I am embarrassed to go to public places and show my face.
