I need help with what’s going on with my face. If it’s damaged, how can I reverse skin texture? (Photo)

I gotten a mild Jessner peel last year in January and ended up picking at it I think it got infected it was itchy for a whole year, I went to get a facial right after and the lady told me to use hydrocortisone cream.. I ended up using the whole tube for 2 weeks (packed it on) and didn't know you weren’t supposed too.. I got a microdermabrasion a few months after. Messed it up even more. The skin texture is just not improving I don’t know what’s going on with my forehead?! Has anyone seen this before?
