I haven’t drank much water til today and since last night got super cracked dry lips but why it’s purple? I Been putting chapstick Vaseline on all day & I barley sent message to my doctor so she’ll probably reply til 2 days. I read online dry corners means fungus or lack of vitamin b12? And cure is Vaseline. A lot of time I do put on lip liner and the corners r suepr cracked the skin coming off but I haven’t used lip liner in whole week?
