What is psoriasis?
Psoriasis (sore-eye-ah-sis) is a common medical condition that occurs when skin cells grow too quickly. The result can be seen as inflamed, thicked and scaly areas of skin. It can can affect other areas, such as the scalp, finger or toes nails and genitals.
In some cases the person may also have sore and inflamed joints at the same time. When this occurs, it is called Psoriatic Arthritis.
Psoriasis is not an infection and is it is not contagious. It cannot be spread by touch or being close to a person with psoriasis. Although it can look like a rash, it really isn’t.
Skin affected by Psoriasis is usually red and flaky.
Psoriasis may seem to be only skin deep, but it does start inside the body – it is caused by the overactivity of your body’s immune system. The extra inflammation makes the skin grow and multiply too quickly. The body is not able to shed these excess skin cells, so they pile up on the surface of the skin.
The most common form of psoriasis appears as raised, red, itchy patches called plaques that are covered with a layer of flaky, silvery-white dead skin cells, called scales.
