I've heard that some people use a steroid cream to treat their psoriasis. Is this safe?

I’m not sure if you mean the topical steroids, or oral corticosteroids.  Topical steroids are generally used for short-term treatment of mild to moderate cases of psoriasis, and are usually applied once or twice daily. Oral corticosteroids are often used in more severe cases, but can be dangerous and should only be taken under medical supervision.
