Reddened skin on the face or body may be caused by genetic factors, environmental heat or cold, or skin conditions including acne, eczema, dermatitis and rosacea. Underlying health problems such as lupus can also cause reddening of the skin, as can specific allergies to substances that cause irritation. It is important to get a diagnosis from a dermatologist before attempting treatment of a specific skin problem, as many different conditions share symptoms but require different treatments.
Change your bed clothes. Discard any bedding that is made of synthetic materials or which you have noticed irritates your skin. To avoid skin redness, your best bet is to use pure cotton pillow cases that are laundered frequently with a gentle laundry detergent.
Humidify your environment. Red skin is often dry skin, and humidification of your home or work area can help reduce redness. Also make sure that your home is not overheated -- high temperatures have a tendency to dry the skin out and therefore cause redness.
Discard any bathing products that aggravate your skin. Red and itchy skin is usually worsened by taking very hot or very cold showers, so when your skin is red it is best to take a warm or tepid shower or bath. Use only gentle bathing products that are designed for sensitive skin, such as those containing oatmeal. Avoid astringent or acidic products based on citrus fruits or tea tree oil.
Find a hypoallergenic laundry detergent that does not make your skin symptoms worse. Also, assess your laundry habits and equipment to make sure that your laundry is being thoroughly cleaned and rinsed of all laundry detergent. To achieve this, you may need to do smaller loads of laundry and use a longer rinse cycle.
Keep a diary of your skin symptoms in order to find out which foodstuffs and drinks worsen skin redness. Typically, spicy foods and alcohol increase skin redness, as they cause flushing of the skin. Your food triggers may be different. Once you have identified some dietary causes of your red skin, do your best to avoid or cut down intake of these foods and drinks.
Moisturize your skin several times a day. Use a product that is designed for sensitive skin. Apply cream to protect your skin before exercising or swimming. If your facial skin appears red, use a green-tinted moisturizer, which will neutralize the visible redness.
Protect your skin year-round with a high-SPF sunscreen.
Do not scrub red or itchy skin. Use cool water, a soft flannel and optionally a gentle cleansing product only to wash irritated skin.
