Redness resulting from inflammation is known as what?

Redness resulting from inflammation is referred to as erythema. This term specifically describes the condition where the skin appears red due to increased blood flow to the affected area as a response to inflammation, irritation, or other stimuli. Erythema can be a temporary condition that resolves as the underlying cause is addressed, or it can be more persistent in chronic conditions.

While teleangiectasia refers to small, dilated blood vessels that are often visible on the skin and may contribute to redness, it is not a direct indication of inflammation. Rosacea is a specific skin condition characterized by facial redness, but it has additional symptoms and triggers that go beyond mere inflammation. Dermatitis is a general term for skin inflammation that can manifest in various forms and causes, but the red appearance of inflamed skin is best described as erythema. Thus, the term erythema accurately encapsulates the key aspect of redness due to inflammation.
