psoriasis on face

I have lived with Psoriasis for donkeys years only on face /head I've tried allsorts of stuff ,cheap stuff , expensive stuff oily stuff creamy stuff and other than hydrocortisone no good. looking on this site I'm seeing all These new wonder drugs from India etc promising modern day miracles ...dont think so... thought i had this thing under control but turns out I'm back to square one again especially this time of year as i like to cycle but Autumn climate in uk causes flare ups grumpy Phil
