question: I have had psoriasis for about 35 years. I am a 46 year old female. The last two to three years my skin condition has gotten considerably worse. I gave up on topical creams/ointments years ago because they are too time consuming, expensive, and uncomfortable. But now, it's so bad I think I have to start treatment again. All parts of my body are affected. What is available that doesn't have to be applied several times a day? I'd like to avoid tanning booths. Thanks for your help.
