Detailed answer

Inflammation is the body's natural response to injury or irritation. It occurs when the immune system releases chemicals to defend against harmful substances. In the case of skin, inflammation can be triggered by various factors such as allergens, irritants, or skin conditions like eczema or rosacea. This inflammation causes blood vessels in the skin to dilate, resulting in redness. The severity of redness can range from mild to severe depending on the level of inflammation. It is important to address the underlying cause of inflammation to reduce skin redness and promote overall skin health.
