Eczema is painless and itchy, some eczema it is mainly manifested as some rough flaking, sometimes even cracking phenomenon in severe cases. This kind of eczema is a chronic process that lasts for years and years and does not go away, and it does not hurt or itch. This is called dry eczema, which is actually an inflammatory condition caused by dry flaky skin that irritates the skin. Because dry skin lacks a sebaceous membrane, it lacks a protective film against external stimuli, making it easier for external stimuli and allergens to enter the skin and cause inflammation. However, this inflammation only manifests itself in the form of rashes as described above, but it can be painless and itchy.
