Psoriasis is a long term (chronic) disorder that causes skin cells to grow too quickly,resuting in thick,white,silvery or red patches of skin.

Normally skin cells grow gradually and flake off about every 4 weeks.New skin cells grow to replace the outer layers of skin as they shed.But in Psoriasis new skin cells move rapidly to the surface of the skin in days rather than weeks.

They build up and form new patches called Plaques.

They most often appears on knees,elbows,scalp,hands,feet or lower back.

It is most common in adults but children and teens may also suffer.


Psoriasis is an auto-immune condition in which the immune cells of body attack the body's own skin cells.It causes abnormally fast growth of cells leading to thick skin and excessive shedding of cells.
