Once you have been diagnosed by a doctor with psoriasis, some form of topical treatment is typically prescribed. These can include lotions, creams, ointments and gels, and they work to drastically reduce swelling, itching and dry skin. These topical treatments work at the problems that are created above the surface of the skin, and they can even slow down the growth of skin cells that are attributing to the plaques (hardened, dry patches of skin with scales) that are created by psoriasis. There are some over-the-counter lotions for dry skin, but they are not as strong as those prescribed by a physician, and they may not alleviate as many symptoms.
