Erythema: Red skin, called erythema, is caused by dilated blood vessels with increased blood flow to the skin. It is usually due to inflammation, infection, or allergy. Rosacea is a common cause of facial redness in adults. Laser can zap tiny blood vessels that contribute to redness. See a dermatologist. Tanning can worsen the condition but the tan will disguise the redness somewhat.
