What causes Psoriasis?

Skin cells can multiply up to 10 times more quickly than usual when someone has the skin condition psoriasis. As a result, the skin develops into red spots that are rough and coated with white scales. In the lowest layer of skin, your body regenerates new skin cells. Until they reach the outermost layer of skin, where they eventually die and flake off, these skin cells steadily advance through the layers of skin. Normally, the entire process takes three to four weeks.
 
The exact cause of psoriasis is unknown. It is believed to be an immune system issue wherein infection-fighting cells unintentionally kill healthy skin cells. Both genetics and environmental factors are thought to be involved. The illness is not spread by others.

Each person with psoriasis will have different triggers, but some typical ones are as follows: 
anxiety, stress , hormonal changes , infections , skin injuries
