Psoriasis is a non-contagious skin disorder that causes chronic scaly red rashes on your skin. It is primarily caused by genetically mediated dysfunction of the immune system. Environmental factors like infections, weather and stress also influence its occurrence. Abnormal activity of immune system alters the cycle of skin cells. The skin cells turnover time shortens from a month to few days, as a result of which immature cells reach surface and get heaped up to form raised red coloured patches with dry and silvery white scales.
It can occur in people of any age group. Although it doesn't spread from person to person, it may develop due to a family heredity.
The skin patches may appear anywhere on the body. Some people may also experience scalp, nail and joint involvement. There can be different patterns of skin involvement like Plaque, Guttate, Inverse, Pustular and Erythrodermic.

Treatment is guided by diseases severity. For limited disease topical medicines are given and in case of extensive involvement oral drugs and or phototherapy is given.
The type of psoriasis treatment will depend upon your symptoms and your medication history. Seek help of the dermatologist about the options that will work for you and are safe.
