For lip biters ect.
Leave your lips alone, don't intentionally ever knock off the buildup, but use products that slow it from creating or staying on your lips. It is better to have a clean surface to apply the products to, so they penetrate and are sterile, but ONLY if you dont knock it off manually and inflame it. Most of the stuff on your lips is the product... the skin is loosely stuck to it and washes of... the buildup that remains is supposed to be there so don't touch it.
When you use the products like I have.. at first you wake u in the morning with a lot of gunk, let the excess gunk rinse away in a bath (not shower) without touching it (again: the buildup that remains is supposed to be there so don't touch it), and then make sure your lips are clean with eye contact disinfectant, rinse with water, put a layer of fucidin over it, then a layer of prevex over it, and do this a few times a day after you eat, before you go to bed. Put a large layer of vaseline over the prevex and other products before bed. Keep doing this. Inflammation disappears and the white gunk stops coming until your EC is gone. Treatment takes a little while, show patience and stick to it unless you are seeing negative side effects.
Stop the fucidin after a few weeks, then ween of the prevex hc, and then the regular prevex. Vaseline you come off last.
