Psoriasis is a skin condition that causes red, flaky, crusty patches of skin covered with silvery scales.

These patches normally appear on your elbows, knees, scalp and lower back but can appear anywhere on your body. Most people are only affected in small patches. In some cases, the patches can be itchy or sore.

Psoriasis affects around 2% of people in the UK. It can start at any age, but most often develops in adults under 35 years old. The condition affects men and women equally.

The severity of psoriasis varies greatly from person to person. For some people, it is just a minor irritation, for others it has a major impact on their quality of life.

Psoriasis is a long-lasting (chronic) disease that usually involves periods when you have no symptoms or mild symptoms, followed by periods when symptoms are more severe.

When to seek medical advice

You should see your GP if you think you may have psoriasis. They can often diagnose the condition based on the appearance of your skin.

Further tests are usually only necessary if the diagnosis is uncertain, in which case you may be referred to a specialist in skin conditions called a dermatologist.

Why it happens

Psoriasis occurs when the process by which the body produces skin cells is accelerated. Skin cells are normally made and replaced every three to four weeks, but in psoriasis this process only lasts about three to seven days. The resulting build-up of skin cells is what creates the patches associated with psoriasis.

Although the process is not fully understood, it is thought the increased production of skin cells is related to a problem with the immune system. The immune system is your body's defence against disease and infection, but in people with psoriasis it attacks healthy skin cells by mistake.

As psoriasis can run in families, there is also thought to be a genetic element to psoriasis. However, the exact role that 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.

The condition is not contagious so it cannot be spread from person to person.

Treating psoriasis

There is no cure for psoriasis, but a range of treatments can improve symptoms and the appearance of the affected skin patches.

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 ineffective 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 the most severe cases where other treatments are ineffective, systemic treatments may be used. These are oral or injected medicines that work throughout the whole body.

Living with psoriasis

Although psoriasis is just a minor irritation for some people, the condition can sometimes have a significant impact on your life.

For example, some people with psoriasis have low-self esteem due to the affect the condition can have on your physical appearance. It is also quite common for someone with psoriasis to develop tenderness, pain and swelling in the joints and connective tissue. This is known as psoriatic arthritis.

Speak to your GP or healthcare team if you have psoriasis and you have any concerns about your physical and mental wellbeing. They can offer advice and further treatment if necessary. There are also a number of support groups for people with psoriasis, such as The Psoriasis Association, where you can speak to other people with the condition.

I have had this condition for years! It came out of the blue, for no reason and simply has stayed with me.
I've tried everything. Topical creams worked for a while, but the condition still returns.
One thing I have noticed though - my skin does not like hot water, I do, I love a hot bath. My skin does not.
Also the areas where I have Psoriasis does not dry at the same rate as 'healthy' skin - it seems to sweat as it is drying? And then when it is dried, flake and become itchy.
Surely this must mean a chemical imbalance?

I was diagnosed with Psoriasis many years ago and I did not spread until recently. It started to look ugly, It spread to my elbows, groin area and very badly to my scalp. One patch appeared on my forehead. I was beginning to get very worried and feeling low.

I have been using Neutrogena T/Gel shampoo for while but it did not stop it. I spoke my Doctor who prescribed Dovobet ointment and at the same time my wife started using 'Palmer's Cocoa Butter Formula cream on her skin and she was so impressed with the results that he asked me try it. Since I was despite I was willing to try anything. I adopted the following routine:

1. Everyday, Wet my head and rub Neutrogena T/Gen shampoo liberally. I also rubbed it on my Psoriasis affected skin

2. I leave it while I shave and brush my teeth
3. Take a shower. Try not to use any others shampoo
4. Dry my hair and skin
5. I put a dab of Dovobet cream on the affected skin
6. Around lunch time and in the evening I rub Palmer's Cocoa Butter Formula cream liberally on the affected skin and also rest of my dry skin.

I suck the above routine or two month now and so happy to say that 100% of the Psoriasis has gone. I wish I had taken before pictures but I was not sure anything going to work.

Now the skin that has Psoriasis is slightly different colour to the rest of the skin.

No more flakes and scratching.

The Neutrogena T/GEL shampoo costs around 6.99 .pounds and Palmer's Cocoa Butter Formula costs around 3.? pounds. Both available from Boots.

Please talk to you Doctor if you want to try my method.

May be medical professional can explain why it is working so well.

I will update this every month on my progress.

Good luck.

I have had moderate psoriasis for many years but have recently been diagnosed as hypothyroid - could there be a connection?

My son has terrible psoriasis, he has been having light therapy since September 2013 3 times a week. Just before Christmas his dosage was increased. He saw a doctor on Monday and had some bloods taken, the doctor told him he might be deficient in something, which is why he isn't getting better, and might need a tablet once a month. My son wasn't very clear (he's 17 and didn't ask). What could this be?

I have had psoriasis for many years and there have been times when both the symptoms and the doctors treatments have really gotten me down.
The worst part is the way people look at me when I they can see the scales especially in the summer.

There are some good natural remedies out there and although they don't cure my symptoms, they have helped immensely. Personally, I've found really good relief form dead sea salts, although they are a little pricey.

I think they are dermasolve or something and it has worked to sooth a lot of my discomfort.

If anyone else has any recommendations, I'd love to hear them...

I was on phototherapy as well and it was quite good but it stopped working for me. I use a psoriasis cream with patchouli and manuka and it is the best thing I have tried apart from the phototherapy.

I would like to query what the consultant stated about ultra violet light/ sunlight and the risk of skin cancer in the treatment of psorasis. Surely the latest research suggests that we in the Northern Hemisphere are not getting enough sunlight resulting in a deficiency in Vitamin D. It is now suggested that we should not cover ourselves in sun cream but to allow ourselves to get some sunlight. I have had psorisus all my life and received ultra violet treatment when in my teens. I know from experience that sunlight definitely helps me and can't wait for the summer. As a result, fortunately as a 72 year old my psorisis it is now minimal but I have to keep alert for any tiny outbreaks.

I was on phototherapy few years ago, it was very effective. My skin became smoother and the bumpy patches disappeared within weeks. But there were some disadvantages so i stopped.
