After using Listerine Total Care Zero before bedtime I noticed in the morning that a thin layer of skin inside my mouth was peeling from my cheeks. I was able to reach inside my mouth and remove a large amount of dead skin. It just peeled away.
I stopped using it for three days - then did it again - the next morning - dead skin again. This can't be healthy nor normal. I've never had other products do this. Back to Crest Mouth Wash for me . . .
