This weird rash on my face is annoying me so much (pics included). Has anyone had it or has it / knows what it is?

Had this for years. Anything like Duac, Azelaic acid and even moisturisers or anti-redness creams make it worse. I haven't put anything on my skin since February 1st and it's still like this. My philtrum and the area just below my lip are normal, and the areas that are red are covered in these little red bumps. It also tingles and stings in the evenings and at night even though I'm not doing anything. I was seen by a doctor weeks ago and she said it looks "very sore" but has no idea what's going on.

It's annoying because before this my skin was perfect. I'm wondering if anyone here has this or has had it?

I used Duac for years, so my skin was blemish-free, but then I began to get episodes of this rash which came in varying degrees of severity and since 2024 it just blew up.

I have very pale skin and before this, the skin on my face was the exact same colour as my neck and my philtrum/area immediately under my lip. In some lighting I look severely sunburned even though I'm not.
