What is Psoriasis ?

Psoriasis is an autoimmune disease that causes raised, red, scaly patches to appear on the skin.

It typically affects the outside of the elbows, knees or scalp, though it can appear on any location.

Some people report that psoriasis is itchy, burns and stings.

The disease is  linked to other health conditions, such as diabetes, heart disease and depression.

Scientists are not yet sure what exactly causes psoriasis.

The disease usually develops between the ages of 15 and 35 - but it can pop up at any time.

Nearly 15 per cent of those with psoriasis develop the disease before age 10.

Typically, something triggers psoriasis to flare.

The skin cells in people with psoriasis grow at an 'abnormally fast rate,' which causes a buildup of psoriasis lessons.

Men and women develop the disease at equal rates - but it affects different races at varying rates.

Nearly 3.5 per cent of Caucasians have psoriasis, compared to 1.9 per cent of African-Americans.
