How to Get my Skin Texture Back After Deep Dermabrasion and Remove Hypopigmentation?

i had dermabrasion done 3years back for deep acne scarring on my cheeks. the doc went a little too deep and ruined the texture of my skin. i now have two huge discolored patches with fine demarcations , full of wrinkles ..enlarged pores. my skin looks like burnt skin as it has turned into plastic texture.scars reappeared. what can i use to get my skin texture back and thicken my skin? and most importantly to remove discoloration. PS. i have Asian skin, and it took 3months to completely heal
