Advice & Tips:
Elocon liniment is a mometasone-based corticosteroid. I use it as needed when the psoriasis starts itching. After applicating Elocon every morning for 4-5 days, and Daivonex every evening in the same period, I'm usually symptom free for a couple of weeks.
In addition to Elocon liniment, I use Daivonex and Methotrexate. The Methotrexate seems to slow down the psoriasis enough so that the Elocon and Daivonex has a chance to drive it back for a while.
I also use Elocon in my outer ears to stop my seborrheic dermatitis. 3 or 4 evenings with applications seems to be enough to stop the seborrhea for a month or so. I don't think the Methotrexate I am taking is having any effect on the seborrhea.
