I've had this same thing happen on and off for 6 or 7 years now. The first time it occurred, it affected my entire lower lip and the area below it, approaching my chin. It was horrifying. My skin was just peeling off in very thin layers and it seemed like it didn't have, I dunno, structural integrity or something. It was like pulling apart wet toilet paper or something. It's like I was falling apart. It felt strange when I'd touch the area , like there was plastic wrap over my skin.
