Red patches on your face appear due to skin irritation, inflammation, or underlying conditions like rosacea or eczema. These patches may look like sunburn, with well-defined borders or diffuse redness.
Your skin turns red when blood vessels near the surface dilate. This happens in response to triggers like allergens, temperature changes, or stress. Chronic conditions cause persistent redness through ongoing inflammation.
