I had it, lots of different places and some were a definite circular shape, on my face they weren't so I went through a number of possible diagnoses and various different medications. I was also going through a period of extreme stress, which I thought I was managing well but my skin told a different story!
I found using hydrating washes on my skin in the shower (dermol 500) and slathering it on after a shower worked well and I used Cetraben on the patches on my face. Cetraben is a greasy emollient, not a nice product to use but it did protect my face from the wind and weather and they healed up well. I still use it if I get any sign of something on my face.
I hope you find something that works for you, I struggled for nearly 8 months to find something, it was quite demoralising and the itching at night stopped me sleeping. fwiw I had several prescriptions from the GP including one that contained a low dose of a steriod, that did work to some extent but as soon as I stopped using it, the patches came back, so frustrating. I don't have the same level of stress now and all is fine, I hope you will be too.
