People with psoriasis may have mild itching alongside occasional stinging sensations. Whereas eczema symptoms often fall into the extreme category, causing severe itching. Because of this intense itching, some people may end up scratching their skin raw, causing bleeding or further irritation.
Psoriasis and Eczema Difference: What Causes What?
According to Dr. Jeffey Millstein, a physician from Penn Internal Medicine Woodbury Heights, the most significant distinction between the two lies in terms of its fundamental causes.
An autoimmune disease such as psoriasis implies that the problem originates from the inside – the immune system.
As a result, skin cells multiply on an abnormal scale, which begins to pile up on the surface and generates white scales. But, eczema is more complicated than a domestic build-up. The rashes could be triggered by different factors like genetics or the environment, which is why you may find it too difficult to pinpoint the root cause.
Another consideration in psoriasis and eczema difference is the reactivity to sunlight. For those who have eczema, their skin can get more sensitive to sunlight. On the other hand, exposure to UV radiation helps slow down the development of psoriasis.
