I am still using acidophilus in a form of soured milk that I found at the supermarket. I apply it before I go to sleep at night and in the morning before I go about my day.
My lips are still building up dead skin though it exfoliates more easily. I can't say that I see any improvement yet.
I'm not sure I understand where this waterproof coating is supposed to come from.
What is the vermillion border? Is it where your lips touch eachother when you have a closed mouth?
