I first have dry chapped lips, and I constantly have to put lip balm on and have seen no improvement. I have woken up and have had puss/yellow crusted lips. I went to a doctor and he didn t know what was wrong. He put me on some type of steroid cream which did help, but it only tamed my condition. Since then I have only used Aquaphor on my lips and I haven t had any crusting since, just chapped lips occasionally (I still put stuff on my lips at least once a day). This was a few years ago by the way. I again recently have red, sore, weeping lips which turn to a yellow crust. What do I have, and how can I treat it? Please help, and thank you for your time!
