Hmmmm I have this for about 3 months and got it from excessive chapstick for sure. I have been using a lot of chapstick and the thing is chapstick tricks your body to beleive that the surface is just fine and your body doesn't make more cells as it suppose to do...and I have left them alone for about 2 weeks now and I notice the crusts getting less thicker.
In addition I have not applied anything I mean ANYTHING....no vasaline if they feel dry I just use my napkin. I have a very clean napkin which I went it with water and after making sure it is damp or even wet I just lightly press it against my lips to make is much more humid...I think the summer heat is helping too anyways it might not look 100% but it looks like chapped lips
HAVE HOPEEE :) and Jdubbs and Daniel along with other people really boosted my hope so thank you to all
