What is the impact of an overactive immune system in relation to eczema?

An overactive immune system plays a significant role in the development and exacerbation of eczema, a chronic inflammatory skin condition. When the immune system is hyperactive, it can respond excessively to irritants or allergens, leading to inflammation in the skin. This inflammation can manifest as redness, swelling, and irritation, which may cause the skin to blister and become more susceptible to infections. The blisters are a direct result of the immune response trying to combat perceived threats, and the broken skin can provide an entry point for bacteria, resulting in infections. This understanding highlights why an overactive immune response is detrimental rather than beneficial in the context of eczema.
