About Psoriasis

Psoriasis is a skin condition characterized by inflamed, red, raised areas that often develop on skin with silvery scales. Psoriasis is a persistent, long-lasting or chronic disease with periods of improvement and exacerbation.


  • Generally seen between 20 to 50 years of age.
  • Often associated with a positive family history of Psoriasis.
  • It can affect any area of the body, the most common being, the scalp, elbows, knees, back, nails, palms and soles.


The exact cause of psoriasis is still unknown. It affects the life cycle of skin cells. Psoriasis causes cells to build up rapidly on the surface of the skin resulting in abnormal fast-growing and shedding of skin cells. Psoriasis is not contagious. Thus you cannot get psoriasis by swimming in the same pool or by eating from the same plate.
