Common skin conditions, psoriasis and eczema affect a significant 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 conditions cause similar symptoms, such as red patches, itching, and irritation, they 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?

Psoriasis is a chronic, autoimmune, and non-contagious disease that affects the skin. It results from an abnormal renewal of skin cells, keratinocytes, in 7 days instead of 21. This leads to the appearance of red, scaly plaques , 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 as alternating periods of flare-ups , during which theskin is dry , intensely itchy, red, and sometimes crusts and lesions appear, followed by periods of remission. Often linked to a family history of allergies, it can occur at any age, although children are particularly affected.

What are the differentiating criteria between psoriasis and eczema?

Although the symptoms may be similar, the two pathologies differ in many aspects.

Appearance of the plates

Do you have thick , well -defined patches covered in thick, white scales that flake off easily, revealing red, painful skin underneath? If so, you likely have psoriasis . People with eczema, on the other hand, will see less thickened patches on their bodies, with areas of crusting and oozing . In addition, their skin is generally drier , and the itching is more intense.

Location of license plates

Generally, psoriasis is located on the elbows and knees , scalp , and back , while eczema tends to appear in skin folds and flexural areas . Furthermore, while eczema is localized, psoriasis can cover the entire body with red patches.

Age of appearance

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

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

What are the aggravating factors associated with 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;

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

• Allergens : dust, animal hair, pollen 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.
