I'm still peeling 2 weeks after microneedling. Is this normal?

Hello, I had superficial acne scars, I went for microneedling which seemed awesome at the begging my skin was peeling mildly, but after 5 days the peeling increased and went from mild to moderate and I started having dark patches of pigmentation around my mouth ( 1 shade darker) . I noticed that peeling exacerbated after walking in the sun for 20 mins. Now I am 2 weeks ++ past microneedling and my skin is still peeling. Is this normal ?!? I am really concerned !
