Overview

Red skin, also known as erythema, is a common symptom that can result from various conditions or environmental factors. The redness occurs when blood vessels near the surface of the skin dilate, often in response to irritation, inflammation, or infection. While it may be temporary, such as after exposure to heat or after physical activity, it can also signal underlying health issues that may require medical attention.

Causes

There are many potential causes of red skin, ranging from mild to serious. Common causes include sunburn, allergic reactions, infections (like cellulitis), skin conditions such as eczema, rosacea, or psoriasis, and physical irritants like harsh soaps or chemicals. Redness can also result from more systemic issues, such as autoimmune disorders (e.g., lupus), or it may be due to flushing from emotions, certain foods, alcohol, or medications.

Treatments

Treatment for red skin depends on the underlying cause. For mild cases, avoiding irritants and using soothing skincare products like moisturizers or aloe vera gel can help. Over-the-counter hydrocortisone creams or antihistamines may be used for allergic reactions or mild inflammation. For more severe or persistent redness, it’s important to consult a healthcare provider who may prescribe topical or oral medications, such as antibiotics for infections or steroids for inflammation, and advise on specific treatments tailored to the condition causing the redness.
