Mayu…That saliva thing is crazy. My lips have, at times, looked like the pictures you’ve posted, but I don’t think that saliva beading thing is happening. A bubble forms, but it’s dry underneath (like an air pocket). Has the beading happened from the very start of the pealing? Maybe the saliva glands were damaged either as a result of the trauma that initiated the peeling or after the fact, through some additional trauma (like peeling, biting, biopsy’s, etc.). I really hate how this peeling condition seems to have so many damn variables and small differences :(
