What treatment is a good for psoriasis?

Mild Psoriasis: The treatment of mild, limited psoriasis vulgaris (elbows, knees) includes topical tar, salicylic acid, and corticosteroid creams. Tolerance may develop and it will be necessary to combine or rotate the therapeutic regimen. For more extensive psoriasis, ultraviolet light or systemic medications may be necessary.

Many Options: Psoriasis is a chronic skin and joint disease for which there are many good treatments. The choice of treatment depends on the severity of skin and or joint involvement and can be as simple as topical treatments or more aggressive systemic/injectable medications. It's important to know that there is no cure for this disease and we still do not know what actually causes it. See a dermatologist.

Tnf inhibitors: Tnf inhibitors do an excellent job of clearing skin in psoriasis.
