Can anyone tell me what this mark on my shin is please? I have had it for a few months. I have it on both shins. It came up a few days after shaving. I haven’t shaved there since - have epilated instead. I have tried everything and it won’t go. I’ve tried Sudocrem, Aveeno, Glycolic acid, scrub, coconut oil, nothing is making it go. I do have psoriasis patches elsewhere, I’m fairly new to it so don’t know if this is that? TIA
