guys sorry but tis got noting to do with diet! i have research like a crazy person and i can tell you diet does help alot but the main key is to rebuild the lips! leave them alone and let them go wild the crusts are a sign that the lips are in a state of panic and are trying to heal them self. i went on the crziest health diet for 3 months didnt see any improvenments. now i just eat healthy aka no processed food what so ever! alot of veggies protein fruit and only drink water. the one thing that every single person has in common that got cured is by not touching their lips and not applying anything im sorry but you can go through all the cure statement they all left there lips alone! the facts dont lie although a healthy Diet may spead up recovery! check it out for your self! good luck guys!
