Once the lips are "FREE" from all products, the body will restore them and they will never be dry again, if the body is fed alkaline foods and the acids removed down the toilet and not out the skin, etc.
The OLD MDs wrote many times that "ALL" people are beautiful "IF" they have no accumulated acid waste in their system. It is the acid body that gets deformed.
I would suggest the "ONLY" sexy lips are pure natural lips.
