The BEST natural remedy bar none, ie the permanent one, is to find the cause:
It's not as hard as you think - and no you won't necessarily get the answer form your doc.
I have found mine (all XX number of them!) and I am able to repeat the results, whether to induce eczema or rid myself of it, 100% every single time I want to - just thought I'd stick it to those who want to say that it is a fluke! And yes, according to all of my dermatologists and doctors, I have eczema, and according to all of them, I cannot get rid of it permanently and can only manage it with corticosteroids, yet I have done it - I don't have to use any hormone-based treatments like corticosteroids!
Ever wonder why people suddenly grow out of it or suddenly get it - especially at key life moments (infant, adolesence, puberty, mid 20s, 40-50) >>>> LIFESTYLE CHANGE!! Moving from breast milk to cow's milk or formulas, moving from formulas to fizzy drinks and burgers?, stress on body while going through puberty and growth, moving out of the parents' home and buying your own washing powder (ie. changing) and maybe doing your own dishes?, metabolism slowing down with age, reduction in exercise and water intake,... the list goes on...
Rather than repeating myself, please read the following 2 answers I have posted about my experiences:
I wish you all the best in your self-discovery and I know that if you are patient and persistent you will find a permanent non-greasy :-D solution!
BTW: did I mention I used to look like a dalmatian during summer? I had tanned skin and white or red patches where the flare-ups were or are. Unless you have another medical condition preventing you, you will need the sun in your search! (Don't go burning or tanning for 15 hours, but a 1/2 hour mid-morning or late afternoon walk would be beneficial both psychologically and physically). We synthesize vitamin D through our skin being exposed to sunlight (like a lot of plants synthesize their own energy needs through the leaves' exposure to sunlight).
