Psoriasis is an autoimmune disease that develops when the immune system works more than required creating cells too quickly. In this condition, there is visible skin inflammation which generally results in red patches. Even Celebs like Kim Kardashian have it! Unfortunately, Psoriasis is incurable.

Medical consultation and treatment reduce the effect of the disease. The severity of Psoriasis differs from person to person. In some people, it is mild and barely noticeable while in others the patches are distinctly visible.


The exact cause has not been deciphered yet. However, through research, it is known that the disease relates to the human immune system and genes play an important role in this.

People with Psoriasis have a faster turnover of skin cells which leads to the building of excessive cells on the top layer of the skin, which in turn results in flaky plaques.

The below-listed conditions trigger Psoriasis:

  1. Stress
  2. A sore throat
  3. The intake of medicines containing lithium and Anti-Malaria medicines
  4. Cold and dry weather
  5. Cuts, scratches or sunburns
  6. Excessive alcohol
  7. Too little or excessive sunlight

People with a weak immune system, like those who have AIDS, Autoimmune Disorders or Cancer, are at a larger risk of getting Psoriasis.
