What causes a facial rash?
Facial rashes can be caused by a wide variety of diseases and conditions, including infection, inflammation, allergic reaction, and autoimmune processes. A sudden or acute facial rash may be due to an allergic reaction or sensitivity to a particular substance, such as a facial moisturizer, food, or medication.
A chronic or long-term facial rash may be caused by such conditions as acne or an inflammatory disorder, such as rosacea. Rosacea is characterized by facial flushing, particularly on the cheeks, and raised bumps that can resemble acne. The precise cause of rosacea is not known, yet effective treatments to control rosacea are available.
A facial rash in an infant may be caused by trapped dead skin cells (milia) or baby acne, although other causes are possible. A facial rash in children can be a sign of many different conditions, including eczema, allergies and viral diseases.
In all age groups, more serious causes include a severe allergic reaction with anaphylaxis (tightening of the airways), bacterial meningitis, and cellulitis (an invasive skin infection that can be caused by streptococcal or staphylococcal bacteria, also called erysipelas).
Infectious causes of facial rashes
A facial rash may be caused by an infection including:
Bacterial infection, such as an infection caused by streptococcal or staphylococcal bacteria
Chickenpox (viral infection)
Fifth disease (mild viral infection in children that can also cause harm to unborn babies)
Folliculitis (inflammation or infection of a hair follicle)
Fungal infection of the skin (also called ringworm)
Herpes virus infection
Impetigo (bacterial skin infection)
Measles (viral infection)
Shingles (viral reactivation of chickenpox infection)
Allergic causes of facial rashes
A facial rash may be caused by an allergic reaction including:
Allergic contact dermatitis, such as an allergy to a facial ointment
- Atopic dermatitis
Eczema (atopic dermatitis), including chronic eczema
Irritant contact dermatitis, such as a sensitivity to a perfume
Autoimmune and inflammatory causes of facial rashes
A facial rash may be caused by an autoimmune or inflammatory disorder including:
Baby acne (skin inflammation triggered by maternal hormones)
Dandruff (seborrheic dermatitis, which can affect the face and neck as well as the scalp)
Rosacea (chronic inflammatory skin disorder)
Systemic lupus erythematosus (disorder in which the body attacks its own healthy cells and tissues)
Other causes of facial rashes
A facial rash may also accompany the following conditions:
Anxiety or stress
Erythema toxicum (benign, noncancerous skin condition common in newborn babies)
Milia (tiny white bumps of dead skin cells and other debris)
Life-threatening causes of facial rashes
In some cases, a facial rash may accompany a serious or life-threatening condition that should be evaluated immediately in an emergency setting. Serious or life-threatening conditions include:
Allergic purpura (an autoimmune bleeding disorder)
Anaphylaxis (a life-threatening allergic reaction)
Erythema multiforme (a type of allergic reaction)
Meningitis (infection or inflammation of the sac around the brain and spinal cord)
Toxic epidermal necrolysis (skin and mucosal loss due to a severe medication reaction)
Questions for diagnosing the cause of a facial rash
To diagnose the underlying cause of a facial rash, your doctor or licensed health care practitioner will ask you several questions about your symptoms. Providing complete answers to these questions will help your provider in diagnosing the cause of your facial rash:
- What does the rash look like?
- When did the rash appear?
- Does the rash appear on only one specific region of the face?
- Have you had the rash before?
- Is the rash spreading to other areas?
- What is your medical and dental history? Do you have any diseases or conditions?
- What medications, supplements or herbal drugs are you taking?
- Have you been in recent contact with any unusual substances or environments, such as exposure to chemicals or unusual plants, taking new medications or supplements, or traveling to a foreign country?
- Do you have any other symptoms?
What are the potential complications of a facial rash?
In some cases, a facial rash can lead to complications, especially if there is severe itching and scratching that leads to breakdown of the skin. Scratching can introduce bacteria or fungus in the layers of skin, resulting in infections. Complications include:
Bacterial or fungal infection of the skin
Cellulitis (an invasive bacterial or fungal infection of the skin and surrounding tissues)
Open sores and lesions
Permanent change in skin texture
Permanent skin discoloration
Serious complications of underlying causes of a facial rash, such as measles or meningitis, can also occur. You can best reduce the risk of complications of a facial rash and its underlying causes by following the treatment plan you and your health care provider develop specifically for you.
