I stumble upon this test. I try to eat this orange bar with marzipan around it.
The problem is that it sticks to lips to the extent that the lips bleed.
Take a look at this picture posted on the forum today.
I already notice that syrup with food colouring agent shows well the boundaries of the exfoliative cheilitis.
That's another test to determine if we suffer from the same thing.
1) White stuff near the lips and in the mouth in general when I wake up
2) The crust becomes white and bigger when wet
3) I do not bite or lick continuously my lips
4) The peeling never stops since the beginning of the condition 10 years ago
