As must be clear by now, I disagree with Badlips about this, and I think washing the lips 4 times a day and swishing the mouth with acidophilus once a day are not incompatible.
In fact, I hope everyone washes their lips at least twice a day, when they are washing their face morning and night, even if they don't use a different soap than they are using on the rest of their faces. I'm sure your doctor would agree.
And not everyone has a raw area on his/her upper lip. I don't, even though my bottom lip has had cheilitis for over a year.
But the proof is in the pudding, and if acidophilus cures cheilitis, in about a week, we will have a lot of cured forum members!
