Do you know the difference between psoriasis and eczema? All types of skin conditions cause discomfort but it’s even more important to properly diagnose a skin condition so that you can treat it appropriately. Eczema or dermatitis is a group of skin conditions where the skin is dry, hot, itchy and scaly. In some severe outbreaks, the skin appears red, raw and bleeding. Eczema is thought to be the body’s reaction to allergies or environmental irritants and whose symptoms are worsened by hormonal fluctuations and stress. [note]Psoriasis is marked by patches of reddish skin which come with a whitish silvery layer. [/note]The psoriasis mostly occurs in areas such as the knees, scalp, elbows and the lower back.


Eczema occurs as a reaction of the body to its environment while psoriasis usually has a genetic link and is the response to certain factors within the body. Eczema has also been known to be triggered by certain types of foods. This means that patients can control the condition by staying away from these foods. [note]While diet may also play a role in controlling psoriasis outbreaks, it can’t affect whether or not they occur.[/note]

Ages affected

Psoriasis tends to show up when the patient is in adulthood while eczema is normally considered to be a childhood condition. However, eczema can continue well into the patient’s adulthood for some.

Psoriasis symptoms

They include small red patches that eventually expand to become scaly, red and silvery plaques, skin inflammation and itchiness, cracked skin that has blisters as well as restricted joint motion. About 10% of people with psoriasis go on to develop arthritis that is caused by psoriatic arthritis. It also causes emotional distress and a significant amount of discomfort.

Eczema symptoms

The patients also have swollen and cracked skin blisters, scaling, blisters and rashes on the legs and arms, red crusty rash on the cheek and rashes near the joints especially inside the elbows and behind the knees.

  • UV rays from tanning beds or sunbathing where UVA or UVB rays are used
  • Itch relief (antihistamine, menthol, capsaicin)
  • Moisturizing (moisturizing body wash, bathing with colloidal oatmeal treatments and avoiding products that dry the skin like perfumes and powders)
  • Skin cleansers (avoid drying soaps and harsh detergents, choose a soap that has a fat or oil base, use unscented soap, use a non-soap based cleanser and patch test your soap before using it )
  • Corticosteroids
  • Using Immunosuppressant like azathioprine, methotrexate and Cyclosporin
  • Using topical immunomodulators like tacrolimus (Protopic) and pimecrolimus (Elidel and Douglan)
  • Using antibiotics when the skin is damaged. Bacteria easily enter the body when it is damaged through scratching. It is also spread via the same way and further infections only aggravate the eczema further. This is why an appropriate antibiotic should be given.
  • Recent studies have shown that a food allergy may spark atopic dermatitis. For these patients, identifying the allergens may lead to an avoidance list to help minimize the symptoms. Dietary factors that have been reported to trigger eczema include coffee (both caffeinated and decaffeinated), dairy products, nuts, eggs, maize (sweet corn) and wheat and soybean products. Please note that these allergies may vary from person to person.

  • Photochemotherapy where ultraviolet A phototherapy (PUVA) and psolaren combine the topical and oral administration of psolaren with skin exposure to UVA light.
  • Phototherapy where UVB light is used several times a week to help people put their psoriasis in remission. Ultraviolet light treatments are frequently used with systemic treatment or retinoids or with topical treatments like calcipotriol or coal tar. This is because there is a synergy in their combination.
  • Systemic treatment where cyclosporine, methotrexate and retinoids are used.

As you can see there are plenty of differences between eczema and psoriasis and comparisons of eczema vs psoriasis. This is why the proper diagnosis for any of these conditions is important. Treating one condition as the other will only worsen an already dire condition especially when dealing with psoriasis. [note]This is because it can elevate to chronic psoriasis which in some cases is life threatening if not treated well. [/note]The difference between eczema and psoriasis is sometimes not very clear but a qualified medical professional should be able to accurately identify what you are suffering from. Remember, the sooner you know what it is, the better as you can begin treatment early.
