Detailed answer

Alcohol has several negative effects on eczema. Firstly, alcohol is a known irritant that can trigger or exacerbate eczema flare-ups, leading to increased itching, redness, and inflammation. Moreover, alcohol is a diuretic, which means it dehydrates the body. This can further deplete the skin's natural moisture and aggravate eczema symptoms. Additionally, alcohol can weaken the skin's barrier function, making it more susceptible to irritants and allergens, thus increasing the risk of eczema flare-ups. It is advisable for individuals with eczema to avoid or limit alcohol consumption to help manage their condition effectively.
