Differences Between Psoriasis & Eczema and How to Treat Them

Skin conditions can often look similar, so it is often hard to tell what you are actually dealing with. Two of the most commonly confused skin issues are psoriasis and eczema (also known as atopic dermatitis). While both can cause itchy, inflamed, and dry patches on the skin, they are very different in what causes them, how they look, what sets them off, and how they are treated.

In this article, we will explain the main differences between psoriasis and eczema, including how to recognize each, figure out what causes them, and look at good treatments for both conditions.

What Is Psoriasis?

Psoriasis is a long-lasting autoimmune skin condition. It occurs when the immune system wrongly attacks healthy skin cells, making skin cells grow up to 10 times faster than usual. As a result, these extra cells build up on the surface of the skin, creating thick, scaly patches that are often red, itchy, and sometimes painful.

Common Symptoms of Psoriasis:

1. Raised, thick patches with silvery-white scales
2. Itching, burning, or soreness
3. Dry, cracked skin that may bleed
4. Often shows up on the elbows, knees, scalp, and lower back
5. May involve joint pain (psoriatic arthritis)

Psoriasis usually shows up symmetrically, meaning the patches often show up on both sides of the body in similar locations. Flare-ups can set off by things like stress, infections, certain medications, drinking alcohol, and skin injuries like cuts or sunburn.

What Is Eczema?

Eczema, or atopic dermatitis, is a long-lasting inflammatory skin condition. Unlike psoriasis, eczema is not an autoimmune condition. Instead, it is because of a weaker skin barrier that lets irritants, allergens, and bacteria get in more easily. This leads to long-term inflammation and extreme sensitivity.

Common Symptoms of Eczema:

1. Red, inflamed patches of skin
2. Severe itching, especially at night
3. Oozing or crusting in more severe cases
4. Dry, scaly, and cracked skin
5. Commonly affects the face, neck, hands, and areas with skin folds

Eczema often starts when someone is a baby or young child, although adults can also develop it. It is often connected to allergies, asthma, or hay fever, and can run in families.

Key Differences Between Psoriasis and Eczema 

While both conditions cause inflamed, itchy skin, there are a few important differences:

1. Psoriasis is caused by an autoimmune reaction that makes skin cells grow too fast while eczema is caused by a combination of environmental triggers, genetic factors, and a damaged skin barrier.

2. Psoriasis shows up as thick, raised, red patches covered with silvery scales while eczema tends to look more like red, inflamed patches that are dry, cracked, or even weeping in bad cases.

3. Eczema often causes very intense itching, which can make it hard to sleep and live normally. Psoriasis may also itch, but is more often comes with a burning or stinging feeling.

4. Psoriasis typically appears on the elbows, knees, scalp, and lower back, while eczema often affects the face, neck, hands, and inside of the elbows or behind the knees.

5. Eczema generally begins in infancy or childhood, and can get better with age while psoriasis can occur at any age but is more commonly diagnosed in adults between 15 and 35 years old.

6. Psoriasis flare-ups are commonly triggered by stress, cold weather, skin injury, and certain medications. Eczema triggers include soaps, fragrances, fabrics, allergens, temperature changes, and even some foods.

Recognizing these key differences is key to helping you or your dermatologist correctly figure out and treat the condition.

Treatment Options for Psoriasis

While psoriasis has no permanent cure, many treatments are available to help manage and reduce flare-ups:

1. Topical Treatments

• Corticosteroid creams to reduce inflammation
• Vitamin D creams like calcipotriene
• Coal tar and salicylic acid to reduce scaling

2. Phototherapy

Exposure to controlled ultraviolet (UVB) light slows down how fast skin cells grow and reduces symptoms

3. Medications

Pills or injections like methotrexate, cyclosporine, or biologics (e.g., adalimumab, secukinumab) for moderate to severe psoriasis

4. Lifestyle Tips

• Moisturize regularly
• Avoid triggers like alcohol and smoking
• Handle stress with relaxation or therapy

Treatment Options for Eczema

Managing eczema focuses on getting the skin barrier healthy again and stopping flare-ups:

1. Moisturizers

Thick, fragrance-free creams or ointments help trap moisture and protect the skin

2. Topical Steroids

Low to moderate-strength corticosteroids are used to reduce inflammation

3. Calcineurin Inhibitors

Like tacrolimus or pimecrolimus, especially for sensitive skin areas

4. Antihistamines

Can help reduce itching and improve sleep

5. Biologic Therapies

Newer medicines like dupilumab (Dupixent) are approved for moderate to severe eczema

6. Avoiding Triggers

Figure out and avoid irritants like harsh soaps, detergents, specific foods, or allergens

Can Psoriasis and Eczema Occur Together?

Yes, while rare, it is possible to have both psoriasis and eczema at the same time. However, because their causes and treatments differ, it is crucial to get a correct and separate diagnosis for each.

Although psoriasis and eczema may look alike at first, they are quite different in cause, symptoms, and treatment. Understanding these differences helps you choose the right skincare approaches, medications, and lifestyle changes to manage your condition.

If you experience symptoms that keep coming back or getting worse, see a certified dermatologist. Early diagnosis and personalized treatment can really improve your quality of life and help you keep healthier skin for a long time.
