Is It Possible to Reconstruct a Lip That Has Been Damaged from Lip Biting?

I used to have a lip biting habit on my upper lip right in the center, it wouldn't bleed or anything but over time I decided to stop the habit. I realized that the skin became raw and worn and many wrinkles developed. Over the course of a few months, new skin began to grow but would continously fall off, and it only grew back in certain areas. It has been cycling and never improving. Since the middle area lacks new skin, I don't know what kind of surgery is available. What are the options?
