The Science of Itch
Eczema itch is more than skin deep; it's a complex interaction between the skin and the nervous system. Inflammation from eczema causes the release of itch-inducing chemicals, triggering nerve fibers in the skin to send itch signals to the brain.
The Role of Cytokines
Cytokines, proteins involved in inflammation, play a significant role in eczema itch. They disrupt normal skin function and increase itchiness by interacting with nerve fibers. Treatments targeting cytokines can help alleviate the itch.
Managing the Itch
Managing eczema itch involves a combination of skincare and medical treatments. Moisturizers and antihistamines can soothe the skin, while topical steroids and other medications help reduce inflammation and itchiness.
