I had a skin reaction that caused a very deep amount of skin to peel. Is there anything that will make it heal? It's been a year

I had a bad skin reaction that caused a deep amount of skin to peel and it has failed to heal even after a year. Is there anything that will make this heal? I tried antibiotics but it has still failed to heal. my skin is now very thin an ripped into bits from all the contracting that had happened as it peeled very deep. A doctor has talked to me about trying a tretinoin or retinoid cream but can't these creams make it even thinner? I am desperate for answers as this has destroyed my self esteem
