Facial redness can be a momentary blushing or flushing on the skin or in certain cases it may last for days, weeks, or months at a time. The primary cause of all types of skin redness is hyper-reactivity of the skin’s vessels; this is when the skin’s vessels dilate quickly, causing a flush of redness to appear on the surface. Additionally, when skin becomes irritated, the skin tissue may become inflamed, which causes redness.
A variety of underlying conditions can provoke or worsen skin redness. External factors, such as UV rays, pollution, and harsh climates may all contribute to facial redness. Several other conditions that cause redness are rosacea, acne, eczema, and dry skin, inflammatory conditions, such as sunburn and vasculitis, stress, genetics, and aging, and allergic or adverse reaction to foods, alcohol, insect bites, and chemicals in skin products.
Quite commonly skin redness is a harmless cosmetic concern; however, there some cases where skin redness is a symptom of something more detrimental. Therefore, if you have persistent, unexplained, or recurring facial redness, you should seek immediate care from a certified and trusted dermatologist. Early diagnosis and treatment of an underlying cause of redness can reduce the risk of serious complications, such as loss of skin, disfigurement, or spread of infection.
