The answer is because peeps want to heal so badly they almost beleive that there is an improvement but there really isn't, I know I've done it, you want it so bad you think you are getting better but in reality its no different I haven't seen anyone who has healed there lips and posted evidence like before and after,and I mean a bad case of before not just a bit of flaky skin.
How many people on here post and so they are nearly cured only tobe posting a few weeks later discussing new ' cure's ' or treatments, well what happened to the one that got you nearly cured?
I might sound negative sometimes but its only becuase I have been on here a long time and heard it all before, but I know people have to try things for themselves and good luck to you.
The only way I have found is to find a good moisturizer dont take skin off until its loose and eat a good diet all that helps the peeling (inflammtion ) but no more.
Until someone can say to me they have left there lips alone for a month and not put anything on them and they are soft like a baby's then I remain skeptical about anything.
