Advice on treatments

My partner suffers with psoriasis - ears, knees but mainly on his stomach spreading to his back. He has had treatment in the past - creams, phototherapy at our local hospital & was told he’s only allowed a certain amount of hours in his lifetime of this. However it has flared up quite badly.. rapidly spreading, very red & sore looking whilst starting to slightly crack. We know this is never going to ‘go away’ however, before contacting gp again I thought I’d ask on here if anyone has found ‘magic’ creams or anything that has helped them personally that we can try out or suggest to gp to reduce redness & stall the spreading. He is incredibly self conscious being in his late 20s and suffering , especially as the warm weather has arrived and I hate he feels this way so want to help in anyway I can. Thanks all.
