Psoriasis, Causes and Triggers: Find Out!

Psoriasis is a chronic skin disease that causes inflammation of the skin. Consequently, the skin turns red, dry, flaky and it’s painful. To read more about Psoriasis and its different types, click here.

What causes Psoriasis?

It has something to do with the immune system. In the case of this disease, the immune system causes a process called cell turnover to work 5x faster (okay that may be an over-exaggeration).

What is cell turnover?

Cell turnover is the process of shedding dead skin cells for younger cells to grow and to surface. This is a continuous process. Skin cells normally grow and shed after 1 month. What happens is that the new skin cells grow in the deepest layer of your skin. They eventually move upwards and through your epidermis, reaching the skin surface.

Within 1 month, they lose their “power” and are no longer living cells. Hence, they become old skin cells and shed.

However, with the speeding of the immune system, in Psoriasis, the cells grow within 3-4 days and do not shed (because it’s too early to do so). Hence, buildup happens on the skin surface and cause discomfort, itchiness, inflammation and pain. The buildup also creates silver-coloured scales, one of the very distinguished characteristics of Psoriasis.

Its triggers?

The trigger for Psoriasis outbreaks differs from person to person. Common triggers include:

  • stress
  • skin injury
  • illness
  • weather

Other triggers, although less common but possible nonetheless are:

  • diet
  • certain medications
  • hormonal changes
  • other immune disorders
