Psoriasis is a common, non-contagious, chronic disease which results from skin cells to rapidly grow with an unknown reason. It usually appears on elbows, knees, scalp and ears. Disease may get better or disappear periodically. Sometimes it may not be visible for years but some patients complain that it gets worse in the winter. Some patients tell that sunlight helps in the summer. It should be cared that immune system has an important role but the certain answer is not that to explain this disease and genetic or environmental factors should be considered.
There are different treatment methods for psoriasis. Treatment method is personal and it changes considering severity of the disease. If it is visible on less than %10 of your skin apart from cream and lotion injection drugs may be administrated. If it is spread to more than %20 of your skin systemic drugs may be used. What you should remember is that there isn't any %100 effective drug and every drug may have side effects. Every treatment method is personal and a treatment method which is successful for someone may not give the same results on somebody else. For Psoriasis disease in which usually rotational treatment methods are applied, light therapy rather than a drug therapy may be applied or the other way around, depending on the period in which the disease is active.
