This started happening about a year ago. One corner of my mouth, the top corner goes through a cycle of getting itchy and swollen for a day or 2, then sometimes the odd tiny blister appears but the main issue is the lip cracks in the corner and a big patch of dry skin appears around the area. So the issue starts on my actual lip but spreads out to my face.
I have to constantly put cream on it to stop it from looking crusty or flaking. Eventually it goes away after a few weeks then it does it again.
Doesn't seem to be any rhyme nor-reason to it - cycle/ stress/ foods/ skin care.
There's not a single wound like a cold sore (I've never had a cold sore before nor has DP!
