Redness

Redness refers to the visible reddening of the skin due to increased blood flow. It may be caused by irritation, allergy, or inflammation.

Redness, also known as erythema, is characterized by increased blood flow near the skin's surface, resulting in a visible reddening. It can be accompanied by sensations of warmth, itching, burning, or swelling. The affected area may range from localized patches to widespread coverage. Underlying causes vary, including allergic reactions, inflammation, infections, irritation from topical applications, or sun exposure. Prolonged or severe redness warrants medical evaluation to rule out more serious conditions.
