Both psoriasis and eczema are chronic skin disorders marked by itching, redness, and inflammation.
Atopic dermatitis, often known as eczema, is a chronic skin illness marked by redness, itching, swelling, and occasionally the development of tiny blisters or dry, scaly patches on the skin. It’s a widespread disorder that frequently begins in childhood and can last into adulthood. Since eczema is not contagious, it cannot be passed from one person to another.
Eczema is characterized by skin inflammation, which can produce redness, swelling, and discomfort. Itching is one of the most common symptoms of eczema, and it can lead to scratching. Scratching can aggravate the skin and make the issue worse.
The skin affected by this condition may become dry, rough, and scaly. Skin might fracture and even bleed in severe situations. Some types of eczema can cause the formation of tiny blisters that ooze or crust over. Eczema commonly arises on folds or creases on the body, such as the inner elbows, backs of knees, neck, wrists, and ankles. It can also have an impact on the face and other parts of the body.
Psoriasis is a persistent autoimmune skin illness characterized by a fast accumulation of skin cells on the skin’s surface, resulting in raised, red, scaly areas. It is a non-contagious disorder with varying degrees of severity that can affect various regions of the body. Psoriasis is frequently chronic and necessitates continual treatment.
In psoriasis, over several weeks, skin cells shed and are replaced by new ones in normal skin. This process is accelerated in psoriasis, causing cells to amass on the skin’s surface. During psoriasis plaques are elevated spots that are often red, inflammatory, and coated in silvery-white scales.
The skin beneath the scales might become inflamed and red. Psoriasis plaques can be irritating, and scratching can cause further irritation and worsen the condition. Psoriasis is most typically found on the elbows, knees, lower back, and scalp, although it can arise anywhere on the body, including the nails and joints.
Psoriasis is classified into numerous kinds, the most common of which are plaque psoriasis, guttate psoriasis (little red spots), inverse psoriasis (in skinfolds), pustular psoriasis (with pus-filled blisters), and erythrodermic psoriasis (affecting huge areas of skin).

Frequently Asked Questions (FAQS)
Q1. Are eczema and psoriasis contagious?
Neither eczema nor psoriasis are contagious. Eczema cannot be transmitted from person to person via direct contact. Psoriasis is an autoimmune disorder and it can’t be transmitted through direct contact
Q2. What are the most prevalent causes of eczema flare-ups?
Allergens (pollen, dust mites, pet dander), irritants (harsh soaps, detergents), stress, temperature fluctuations, and specific materials are all common causes.
Q3. Can psoriasis affect portions of the body other than the skin?
Yes, psoriasis can damage the nails (psoriatic nail alterations) and the joints (psoriatic arthritis), causing joint discomfort and inflammation.
Q4. Can kids get eczema or psoriasis?
Both disorders can occur in children. Eczema typically begins in childhood, although psoriasis can appear at any age.
Q5. Do I need to see a dermatologist about my eczema or psoriasis?
