A Word From Verywell

Rosacea, psoriasis, and eczema are common skin problems with some shared—and some unique—symptoms, triggers, and treatments. Aside from evaluating these issues, your healthcare provider will also consider other skin conditions that mimic these three. As some can be more serious, a professional evaluation is best.

Frequently Asked Questions

Eczema and psoriasis are unrelated skin conditions. One can not progress to the other, however it is possible to have both at the same time. Experts believe environmental and genetic factors cause eczema. Psoriasis is an autoimmune disease, which is when the immune system attacks the body.

Yes. One does not cause the other, but it is possible to have both at the same time. Both can be worsened by some shared triggers.

Causes of Psoriasis and Eczema

Both eczema (also known as atopic dermatitis) and psoriasis are thought to have the same cause: an immune system that kicks into overdrive and mistakenly attacks your own body. But the precise process is different for each condition.

"It's different wings of the immune system," said Emily Newsom, MD, assistant clinical professor of dermatology at UCLA David Geffen School of Medicine.

In psoriasis, overproduction of certain immune-system chemicals causes the outer layer of skin cells to go through the life cycle—forming then sloughing off—in just days rather than a month. The result is a layer of super-fast-forming cells building up on your skin. That's what causes the thick coating of red, silvery scales on your skin that are characteristic of plaque psoriasis—the most common type of psoriasis.

Eczema affects the ability of the skin to protect against outside irritants and allergens.

Pictures of Different Types of Psoriasis and Eczema

Psoriasis and eczema are both skin conditions that have similar symptoms, including skin irritation and inflammation. Some kinds can cause discolored or hyperpigmented skin.

The symptoms of psoriasis and eczema may look the same, but they have different causes. Psoriasis is an autoimmune condition that causes skin cells to build up and become inflamed. Eczema is usually caused by reactions to irritants, allergens, or triggers like stress or dehydration.

And they don’t always appear at the same times. While psoriasis is more common when you’re an adult, eczema tends to show up more frequently in children.

Psoriasis is an autoimmune condition resulting from your white blood cells mistakenly attacking skin cells instead of bacteria or other infectious substances.

There are several types of psoriasis:

• Plaque psoriasis results in patches of inflamed, scaly skin that have a white or silver appearance. It tends to show up on your scalp, knees, or elbows.
• Pustular psoriasis shows up as large areas of reddish or purplish inflamed skin covered in white blisters filled with pus. It’s most common on your feet or hands.
• Inverse psoriasis causes skin inflammation that looks shiny and red. It’s common in areas like your armpits and groin.
• Nail psoriasis shows up as grooves or pits, as well as noticeable changes in color in your fingernails or toenails. You may also see what looks like blood underneath the nails.
• Guttate psoriasis results in relatively small spots that look pink or purple. They tend not to look as scaly or thick as other types of psoriasis. It usually shows up on your legs, arms, or torso.
• Erythrodermic psoriasis causes severe, burned-looking skin that’s widespread, and may result in large areas of skin peeling off. You may also experience a fever with this type.
• Scalp psoriasis shows up as itchy, scaly patches of skin on your scalp that may look pink, red, dark brown, or purple.
