Psoriasis is a chronic inflammatory disease of the skin that is not contagious. It can occur at any age. The cause of psoriasis is not known, but it is partly genetic and can be triggered by external factors such as stress, infections, and some medications. Psoriasis is characterized by the appearance of red patches covered with a thick silvery scale. The affected areas are mainly located on the elbows and knees, but lesions may also involve the scalp, palms, and soles.
Treatment of psoriasis depends on the severity and extent of your lesions. For mild and localized disease, creams with cortisone, vitamin D, salicylic acid or urea are helpful. For more severe disease, your dermatologist may suggest ultraviolet light therapy, or pills such as methotrexate, acitretin or cyclosporine. Recently, biologics, a new category of injectable therapy has been introduced into the market.
It is important to understand that the currently available treatments reduce and even clear symptoms, but they do not cure the disease. The disease can recur after stopping the treatment. Therefore, it is important to follow up with your dermatologist.
