While you might have heard about a skin condition called psoriasis, you could be unaware of some of its causes and how to treat it.
Whether it’s you or someone you know who is experiencing psoriasis, here’s a roundup of the key things to know about it.
The NHS website explains: “Psoriasis is a skin condition that causes flaky patches of skin which form scales.
“On brown, black and white skin the patches can look pink or red, and the scales white or silvery. On brown and black skin the patches can also look purple or dark brown, and the scales may look grey.”
Where do psoriasis patches appear on the body?
You can find psoriasis patches anywhere but usually, they flare up on your elbows, knees, scalp and lower back, according to the NHS.
While some people can experience large patches of psoriasis, most will only have small ones.
Sometimes these patches can become itchy and sore.
How many people in the UK have psoriasis?
The NHS explained: “Psoriasis affects around 2 in 100 people in the UK. 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. For some it's just a minor irritation, but for others it can have a big impact on their quality of life.”
The chronic disease is long-lasting but it’s not uncommon for it to involve periods where there are no symptoms or perhaps mild symptoms and then periods where it is more severe.
Why do people have psoriasis?
People with psoriasis might wonder why they have it and what causes it.
The NHS said: “People with psoriasis have an increased production of skin cells.
“Skin cells are normally made and replaced every 3 to 4 weeks, but in psoriasis this process only takes about 3 to 7 days.
“The resulting build-up of skin cells is what creates the patches associated with psoriasis.
“Although the process is not fully understood, it's thought to be related to a problem with the immune system.”
Is psoriasis hereditary?
While psoriasis can be hereditary, it isn’t a contagious condition so it can’t be spread between people.
The NHS said: “Psoriasis can run in families, although the exact role genetics plays in causing psoriasis is unclear.
“Many people's psoriasis symptoms start or become worse because of a certain event, known as a trigger.
“Possible triggers of psoriasis include an injury to your skin, throat infections and using certain medicines.”
How to treat psoriasis and can you cure it?
If you think you have this skin condition, you should speak to your GP who can diagnose it.
There is no cure for psoriasis but some treatments can help improve symptoms and the way your skin looks.
The NHS said: “Your doctor will ask you about how much the condition is affecting your everyday life.
“In most cases, the first treatment used will be a topical treatment, such as vitamin D analogues or topical corticosteroids. Topical treatments are creams and ointments applied to the skin.
“If these are not effective, or your condition is more severe, a treatment called phototherapy may be used. Phototherapy involves exposing your skin to certain types of ultraviolet light.
In severe cases, where the above treatments are ineffective, systemic treatments may be used. These are oral or injected medicines that work throughout the whole body.”
Chartered Chemist and founder of SOS Serum Skincare, Bruce Green, said: “Although there’s no cure, symptoms can be managed effectively. Mild cases are often treated with topical creams such as vitamin D analogues or corticosteroids to slow cell turnover and reduce inflammation.
“More persistent or severe psoriasis may benefit from phototherapy (targeted UV light treatment) or systemic medications taken orally or by injection.
“When managing psoriasis, lifestyle plays a huge role in keeping flare‑ups at bay. Avoid common triggers such as stress, smoking, and excessive alcohol, and keep sunlight exposure in moderation.
“A diet rich in anti‑inflammatory foods like omega‑3s can help, while cutting back on sugar and processed items may also make a difference. Stick to a simple daily skincare routine, choosing products formulated for sensitive skin — and absolutely avoid fragrances.”
