I am glad to read this, ASC2010!
I think I had every possible dermatological condition under sun and I can certify that dermatology is like black magic! These conditions are very slow to clear so one needs to be very patient.
In my twenties had my whole face covered in rash, knew every dermatologist in town, and only after ca 5 years found one who knew what it was. It took two years to clear, and it turned out to be digestive issue caused by stress, treatment included tranquilizers.
From that experience I learnt that less is more, meaning that creams should be very simple (used Nivea on face for years after that, until meno), and I wished I knew of eczema moisturizers much earlier.
Boots, as well as Superdrugs, have separate shelves with them, where medicines are. Have a good look there..and check prices on Amazon!
Best wishes!
