Is a chemical peel 3 months after the PicoSure laser a good way to treat PIH from pico?

Hi, I am an Asian woman who I did picosure laser three months ago for sun damages. Unfortunately, my dark sports came back darker three weeks after the treatment. I have been using trenoinin cream at night and expensive skinseutical products in the morning. So my sports are fading after three months, but they are still there and I hate them. I am wondering if any chemical peel would help or I should wait patiently more three months? I am so afraid that chemical peel will give me PIH.
