Common skin conditions, psoriasis and eczema affect a large number of French people, 2% for the former, and nearly 34% for the latter according to Sanofi and INSERM ( National Institute of Health and Medical Research). While these two pathologies cause similar symptoms, such as red patches, itching and irritation, the latter have different causes , manifestations and treatments .

Blue Skincare helps you differentiate between psoriasis and eczema , recognize and optimally treat these skin conditions with targeted care.

Psoriasis and eczema: what are they?

A chronic, autoimmune, non-contagious disease that affects the skin, psoriasis results from an abnormal renewal of skin cells, keratinocytes, in 7 days instead of 21. This leads to the appearance of red, scaly patches , often covered with small white scales, on different areas of the body, including the elbows, knees, scalp and lower back.

Eczema , or atopic dermatitis, is an inflammation of the skin that can be caused by genetic, environmental or allergic factors. It manifests itself by alternating periods of crisis , during which theskin is dry , intense itching, redness and sometimes scabs and lesions appear, followed by periods of calm. Often linked to a family history of allergies, it can occur at any age, although children are particularly affected.

What are the criteria for differentiating psoriasis from eczema?

Although the symptoms may be similar, the two conditions differ in many ways.

Appearance of the plates

Do you have thick , well- defined patches covered in thick, white scales that peel off easily, revealing red, painful skin underneath? If so, you probably have psoriasis . People with eczema will see patches that are less thickened, with areas of crusting and oozing . The skin is also usually drier , and itching is more pronounced.

Location of the plates

Generally, psoriasis is located on the elbows and knees , scalp and back , while eczema is more likely to be found in the folds and flexion areas . Furthermore, while eczema is localized, psoriasis can cover the entire body with red patches.

Age of onset

Very rare in infants, psoriasis can begin in childhood, with a rash all over the body, taking the form of small plaques. However, according to the aforementioned INSERM study, only a third of psoriasis cases occur before the age of 20.

Eczema , on the other hand, usually appears in childhood , from 3 months of age. While most cases of atopic dermatitis gradually disappear over time, 10 to 15% of cases persist into adulthood .

What are the aggravating factors linked to these two conditions?

Eczema and psoriasis can be aggravated by various external and internal factors:

• Stress , whether emotional or physical;

• Viral or bacterial infections , such as tonsillitis;

• Cold, dry weather or excessive heat can dry out the skin and trigger flare-ups;

• Certain medications such as beta-blockers or Non-Steroidal Anti-Inflammatory Drugs (NSAIDs);

• Allergens : Dust, animal hair, pollens or certain foods can cause allergic reactions leading to eczema flare-ups;

• Irritants such as chemicals, soap, excessive heat or humidity can irritate the skin and cause inflammation.
