What works for facial psoriasis?

Hi I'm 22 and realized I had psoriasis at the end of my first year of uni I had no idea what it even was until that moment. Basically over the summer I was prescribed methotrexate and that worked wonders for the next 2 years and made it mainly manageable however I've now been taken off the methotrexate and onto dovobet because I take it that you can't use methotrexate forever and have never found something which works for facial psoriasis. My doctor recommended to me cetaphil as something which could help but I wonder if anyone else had any other recommendations.
