I started getting this around age 25 and I’m 33 now. I thought it was from my cat, but even after not being around my cat for months at a time, I still would get it. I also went to a dermatologist and basically he said they don’t know why this happens and it seems like an allergic reaction in the sense that the skin is hyper reacting to something and causing the red itchy skin and flaking. For me, it gets the worst when I skip a shower or if I sweat a lot. Especially if I go to the gym and don’t take a shower right after. Hydrocortisone cream works well at stopping it. Facial hair makes it worse. Once I shaved off my goatee, it reduced by a lot. I get it on one eyebrow, my upper lip/nose creases, and parts of my scalp near my hairline and some parts of my cheeks. It does fucking suck, it’s another thing I have to worry about all the time and it makes your skin look older and patchy. I used to ha e the best skin too.
