One cause of facial redness includes a skin condition known as rosacea, which produces visible blood vessels on the skin that elevate into bumps or pimples, explains WebMD. Additional causes of facial redness include acne, burns, dermatitis, bites or stings, and a drug allergy, according to Healthline.
Flushing can also cause facial redness, according to Cleveland Clinic. Flushing is an episodic attack on the face when skin reddens, warms and burns, especially on the neck and face. Flushing that occurs over an extended period of time can lead to skin conditions such as telangiectasia or classic rosacea.
Rosacea is a common cause of facial redness and can worsen with exposure to sunlight or stress, alcohol consumption, spicy foods, and cosmetics that irritate the skin, according to WebMD. The redness typically starts on the cheeks, chin, nose and forehead, and appears, disappears and reappears over time.
Skin conditions that cause facial redness, such as rosacea or acne, are often treated with topical creams or antibiotics to reduce swelling, flushing and discoloration of the skin, explains WebMD. Allergic reactions to medication or cosmetics can be treated by discontinuing the cause of the facial redness and consulting with a physician to determine an alternative medication.
