Redness

Skin redness is a common symptom of many medical conditions, often caused by inappropriate melanocyte activity, inflammation of the underlying layer of the skin, or irritation from environmental exposures. It can range from a mild pinkish hue to extensive redness covering large areas of skin. A dermatologist can help determine the cause of the redness and the best course of treatment. In some cases, skin redness is caused by an overactive response of the melanocyte cells. The melanocytes are responsible for pigmentation, and increased activity may cause patches or areas of the skin to appear pink, red, or even purple. In other cases, this kind of hyperpigmentation is genetic or a result of hormonal changes in the body. Inflammation is a common cause of skin redness, and can be caused by infections, autoimmune conditions, and other conditions. The redness is generally accompanied by heat and swelling, and may also cause itchiness and pain. Many inflammatory skin conditions are treated with topical or oral corticosteroids. Irritation from environmental exposures is another common cause of skin redness. This can include exposure to ultraviolet radiation from the sun, contact with certain plants or chemicals, and metal allergies. Treatment for this type of redness typically involves avoiding the environmental exposures, as well as using topical medications such as corticosteroids and antibiotics. It is important to consult a dermatologist for any redness on the skin that does not resolve after a few days, or if the redness is accompanied by other symptoms such as heat, swelling, or blisters. Redness can be harmless, but when it is a sign of a more serious underlying condition, proper diagnosis and treatment can help prevent long-term complications.
