most of my top lip is %100 now, apart from the triangle, which is still healing. The bottom lip is takes longer but the corners are healed and the top of the bottom lip. The bottom of the bottom lip is taking longest, which probably takes the longest to redevelop because i remember that was the hardest(bloodiest) to peel. This is healing sort of like a scab, quite different to how i imagined it to heal but i remember a boy in my class that ripped the skin off his lips and it healed like a scab also, he must of had the right moisture(NMF) in his lips for it to heal correctly . Wherever the skin isn't fully developed(normal) is overgrowth(i wouldn't call it dead skin). The overgrowth will come off permanently when the skin underneath is fully healed, from looking at the example of my top lip and corners of my bottom lip.
. It doesn't turn white though. I need to go buy more of this stuff before i run out of this one. It could be the Urea or the hydrogen Peroxide... but it's working so i'm not really that concerned. I don't think Urea alone has been tried by anyone on here.
