Psoriasis and eczema can look similar at first glance, both leaving skin red, itchy and inflamed, but they are different conditions with different causes and treatments. The quickest way to tell them apart is often the itch and the appearance: eczema tends to be intensely itchy with weepy, cracked skin, while psoriasis produces thicker, scaly plaques. This guide explains the differences clearly and how each is managed. Our eczema and psoriasis page sets out treatment options, all prescribed after a clinical assessment.

What Is Eczema?
Eczema, most commonly atopic eczema, is a condition in which the skin barrier does not work as well as it should, allowing moisture out and irritants in. This leaves the skin dry, inflamed and extremely itchy. It often starts in childhood and is linked to allergies, asthma and hay fever, which tend to run in families. Eczema typically appears in the creases of the elbows and knees, on the hands, neck and face, and it can flare and settle over time.
What Is Psoriasis?
Psoriasis is an immune-driven condition in which skin cells are produced far too quickly. Instead of being shed gradually, they build up on the surface, forming raised patches known as plaques. These are usually covered with silvery-white scale and most often appear on the elbows, knees, lower back and scalp. Psoriasis can also affect the nails and, in some people, the joints, a condition called psoriatic arthritis. It tends to begin in adulthood and follows a pattern of flares and remissions.
How to Tell Them Apart
While only a clinician can diagnose either with certainty, several features help distinguish them:
- Itch: eczema is usually intensely itchy; psoriasis can itch but is often less so, and may feel sore or burning.
- Appearance: eczema looks red, dry, sometimes weepy and cracked; psoriasis forms thicker, well-defined plaques with silvery scale.
- Location: eczema favours the creases of joints; psoriasis favours the outer surfaces such as elbows and knees, plus the scalp and lower back.
- Age of onset: eczema often starts in childhood; psoriasis more often begins in adulthood.
- Associated features: eczema links with allergies and asthma; psoriasis can affect nails and joints.
How Eczema Is Treated
Eczema treatment focuses on repairing and protecting the skin barrier and calming inflammation:
- Emollients (moisturisers) used generously and often are the cornerstone, even when the skin looks clear.
- Topical steroids to settle flares, used in the right strength for the area and duration advised.
- Avoiding triggers such as soaps, certain fabrics and known irritants.
- Other treatments for more severe cases, prescribed and monitored by a specialist.
How Psoriasis Is Treated
Psoriasis treatment aims to slow the overactive skin cell turnover and reduce inflammation:
- Topical treatments including vitamin D analogues, often combined with a steroid, such as Dovobet gel for suitable cases.
- Emollients to soften scale and ease discomfort.
- Coal tar and salicylic acid preparations for some types and sites.
- Phototherapy and systemic or biologic treatments for moderate to severe psoriasis, under specialist care.
Because the underlying mechanisms differ, a treatment that suits one condition will not necessarily suit the other, which is why getting the right diagnosis matters.
When to Seek Help
See a clinician if you are not sure which condition you have, if over-the-counter measures are not controlling your symptoms, if the affected area is widespread or painful, or if your skin becomes infected, with increasing redness, weeping, crusting or fever. Both conditions are long-term but very manageable with the right plan, so it is worth getting a proper assessment rather than guessing.
Living With a Long-Term Skin Condition
Understanding psoriasis vs eczema is not only about telling them apart on the skin; both are long-term conditions that can affect confidence and quality of life. Flares can be uncomfortable and visible, and the daily routine of creams and treatments takes effort. Acknowledging this side of things is part of managing them well.
Both conditions are also linked to wider health. Psoriasis in particular is associated with joint problems and an increased cardiovascular risk, so it is worth more than skin-deep attention. Eczema can disrupt sleep through itching. For both, identifying triggers, sticking with emollients, and keeping in touch with your clinician when things change make day-to-day life considerably easier.
Important: This article is general information and does not replace a diagnosis. Psoriasis and eczema can resemble each other and other skin conditions, so accurate diagnosis by a clinician guides correct treatment. Prescription skin treatments, including topical steroids, are supplied only after a valid consultation. You can start a consultation where appropriate.
Frequently Asked Questions
How do I know if I have psoriasis or eczema?
Eczema is usually very itchy, red and dry, often in the creases of joints, and frequently starts in childhood. Psoriasis forms thicker, silvery-scaled plaques on areas like the elbows, knees and scalp and often begins in adulthood. A clinician can confirm which it is.
Can you have both psoriasis and eczema?
Yes, it is possible to have both conditions, though they are separate. If your skin shows mixed or unusual features, a clinician can assess and tailor treatment to each.
Are psoriasis and eczema treated the same way?
No. Both use emollients, but eczema relies on barrier repair and calming flares, while psoriasis treatment aims to slow rapid skin cell turnover, often with vitamin D analogues, phototherapy or specialist medicines for severe cases.
Is eczema or psoriasis contagious?
Neither is contagious. You cannot catch or pass on either condition. Both are driven by internal factors, an impaired skin barrier in eczema and an overactive immune response in psoriasis.
