Psoriasis and eczema: what’s the difference?


Colder weather means more preparation for people with skin conditions. But, without a diagnosis, you might find it hard to treat your skin properly. So, what is the difference between eczema and psoriasis?

As the temperature and humidity drop in the air, healthy skin can become dry and aggravated. In fact, it’s thought that 48% of people report dry skin when it’s colder. Skin that is prone to eczema and psoriasis is in even more danger. 

Eczema and psoriasis are both inflammatory conditions meaning that without natural moisture in the air, dry skin can trigger off flare-ups. Although both conditions cause flaking, itchiness and discomfort they are different when it comes to the science. 

What is the difference?

First of all, psoriasis affects a smaller portion of the population. It only affects around 1.5% of the UK population whereas around 15% of adults and 7% of children live with eczema. This can sometimes mean that getting a diagnosis for psoriasis is sometimes a little tricky. 

Psoriasis is caused by an overactive immune system which leads to skin cells being replaced more quickly than they should be. Normally, new skin cells are made, reach the top layer of skin and flake off in around three to four weeks. However, if you live with psoriasis, this process only takes around three to seven days. When skin cells that aren’t fully developed reach the top of the skin barrier, they build up quickly and cause flaky, red patches that are covered in silvery scales. 

Atopic eczema is different because it is caused by numerous triggers that differ from person to person. Your eczema could be caused by allergens, family history, soaps, weather and even stress. These triggers cause an inflammation of the immune system which leads to irritated skin. 

How can I tell which one I have? 

Dermatologists know the difference between the two conditions, but most of us need some extra tips. Here are the key differences: 

What it feels like: Eczema is itchier than psoriasis, so much so that people with eczema scratch so much that they break their skin. On the other hand, psoriasis can cause more of a stinging or burning sensation. 

Where it is: Both of the skin conditions can happen anywhere but the patches typically show up on slightly different areas of your body. Eczema normally shows itself around joints, on your hands, neck and around your eyes. Whereas, psoriasis mostly materialises on your face, scalp, palms and lower back. 

What it looks like: Psoriasis patches tend to be more raised and patchy than eczema, which is likely to be more rough, red and infected because of scratching. Also, if you think you have psoriasis, you should be on the lookout for the telltale silvery plaque scales that form on the top of the irritated skin. 

Do psoriasis and eczema have different treatments? 

The two skin conditions can be managed by keeping the skin moisturised, clean and steering clear of triggers. However - as always - the conditions respond to other treatments differently. 

Different topical medication is used for the management of each condition and you should speak to a dermatologist about which ones are best for you and your skin. Also, salicylic acid can help with the scaliness of psoriasis whereas applying cool compresses can help ease the itchiness of eczema.
