Psoriasis is very common and affects 2% of the population – not just Kim Kardashian.
It can start at any age, but most often develops in adults between 20 and 30 years old and between 50 and 60 years old. It affects men and women equally. The severity of psoriasis varies greatly from person to person.
Certain genes have been linked to psoriasis, so you are more likely to get it if someone else in your family has it. It is not contagious.
Psoriasis is a chronic (long-term) skin disease that causes red, scaly skin that may be painful, swollen or hot.

There are periods when you have no symptoms or mild symptoms, followed by periods when symptoms are more severe (called ‘flare-ups’).
Complications of psoriasis
Some people with psoriasis develop a complication called psoriatic arthritis. This shows itself as tenderness, pain and swelling in the joints. It can affect any joint in the body but often affects the hands, feet, knees, neck, spine and elbows.
It is also the commonest cause of dactylitis (‘sausage fingers and toes) that King Charles may have. See below.
The severity of psoriasis varies greatly from person to person. For some it is just a minor irritation, but for others it can have a big impact on quality of life.
