I’ve had psoriasis for...twenty years, gave up on dovebet - it does improve it, but I found as soon as I stopped it came back with avengence.
The best things I’ve found for treating it without steroids are; MG217 cream - it’s coal tar based and smells DISGUSTING but without a doubt it is the best product I’ve had. Especially on stubborn patches.
If you have it in your scalp - Capasal shampoo really worked for me, by the end of one bottle it had completely settled - now I don’t have it in my scalp at all.
Final thing is - be aware of what makes it worse. For me that’s wine and beer, bad stress and poor diet. Likewise - it seems better when I eat well, avoid dairy and white bread and when I’ve seen the sun. The more you look at what triggers you have, the more obvious it may become how you can manage it and encourage remission rather than suppress it with steroids. At its worst, it covered 25% of both legs, my elbows, my scalp, behind my ears, my cleavage and on my stomach. Now I have three patches the size of a ten pence piece.
I’ll warn you now, it doesn’t go away over night!
