Little update - I have now spoken to 2 GP's that saw the images and one of them is saying the it looks like Rosacea and the other that it can be Polymorphic light eruption ?!
oh my. Well, anything on the face is troublesome. ANY other symptoms? Does it itch? I am glad you are working with your doctor and they are trying to treat you. It's hard to tell things from pictures. Is it that bump under your eye that you are concerned with or is there a patch below that? Sometimes hard to tell from pics, right? Here's info on polymorphic light eruption. https://www.mayoclinic.org/diseases-conditions/polymorphous-light-eruption/symptoms-causes/syc-20355868 Basically that is a reaction to getting sun. Got any history of reaction to UV light or photo sensitivity? Sometimes when that is suspected, they look into the autoimmune disorder of lupus as well.
Rosacea is pretty common. https://www.mayoclinic.org/diseases-conditions/rosacea/symptoms-causes/syc-20353815 It's more common in middle aged women but anyone can get it. There's a whole bunch of things that make it worse. Even stress. They manage the symptoms if this turns out to be the case. Good hygiene is important, reducing stress, sometimes medication is prescribed. And even laser treatment can be done.
