Psoriasis may be found on any part of the skin but is usually found on the scalp, knees, elbows and lower back.
Psoriasis is not an infection. You can't catch it by touching the affected skin of someone who's got it.
What Causes Psoriasis?
Immune System

| Immune system |
The immune system plays a key role in psoriasis.
If you have psoriasis, your white blood cells known as T cells attack healthy skin cells by mistake, as if it were fighting an infection.
This mistaken attack causes new skin cells to develop too quickly, resulting ultimately in elevated scaling plaque of psoriasis.
