I suffer with psoriasis in the ear canal and have micro suction with dovonex placed inside my ear and it works for a few months
I found that the cream I found at Walmart called Dermarest seem to help. I have it around my eyes and nostrils along with Vaseline. I put it on at night.
I recently discovered 'Moo Goo' in the local health shop. They have a particular one called 'Moo Goo cream for the scalp, hairline and eyebrows'. I tried several other Moo Goo products which the shop gave me in sample size, and the scalp one works very well on my forehead and in my ears too. I went back and bought the £17 pump bottle and so far I've found it good for several areas but particularly my forehead and between the brows; my ears and at the sides of my nose.
It is early days yet (only a couple of weeks), but so far it's a case of keep using it every time I get a whiff of psoriasis on my face.
I have it in my ears and I've recently started using witch hazel in combination with plain Vaseline. Seems to be helping so far but it's only been a few days.
