Hello Pyrrhus - i just read your post and i wanted to share that I seem to have something very similar to you. My allergist/immunologist put me on Protopic (Tacrolimus) - it's an immune response cream similar to a steroid but not a steroid. I've been using it for several years now and my experience is identical to yours. When i use for a few days the dryness and redness go away. I stop and then 1-2 weeks later it comes back horribly. Swelling and cracking under my eyes - cracking around my lips. I just hate it. I do not want to be on the cream any longer either. Have your symptoms ever recurred?
