The Bottom Line

The butterfly rash — a red flush across the cheeks and nose — is one of the most recognizable signs of lupus (SLE), an autoimmune disease that can affect the skin, joints, kidneys, and other organs. The rash is often triggered by sun exposure and comes and goes with disease flares. Early diagnosis and treatment can protect your health and quality of life.

What Is the Lupus Butterfly Rash?

Systemic lupus erythematosus (SLE), commonly called lupus, is an autoimmune disease — your immune system mistakenly attacks your own body's tissues. The butterfly rash (also called the malar rash) is one of its most well-known signs. It appears as a red or pinkish flush that spreads across both cheeks and over the nose, forming a shape that looks like butterfly wings.

About 30–50% of people with lupus develop this rash at some point. It can appear flat or slightly raised, and the skin may feel warm. Unlike rosacea or a sunburn, the butterfly rash of lupus is linked to immune system activity and tends to flare alongside other lupus symptoms.

Signs and Symptoms

  • Red or pinkish flush across both cheeks and the bridge of the nose in a butterfly shape
  • Rash may be flat or slightly raised, sometimes with slight scaliness
  • Skin feels warm; the rash may worsen in sunlight
  • Rash comes and goes, often worse during lupus flares
  • Other lupus skin signs: hair thinning, mouth sores, round scaly patches (discoid lupus), sensitivity to UV light
  • Systemic symptoms: fatigue, joint pain, fever, and swelling in other body systems

What Causes Lupus and Its Rash?

Lupus develops when the immune system loses its ability to tell the difference between your own cells and foreign invaders. It attacks normal tissue, causing inflammation throughout the body. On the skin, this inflammation creates the butterfly rash and other lesions.

Lupus is more common in women (especially women of childbearing age), African Americans, Hispanics, and Asians. Sun exposure (ultraviolet light) is one of the most common triggers for both the rash and broader lupus flares. Stress, infections, and certain medications can also trigger flares.

Diagnosis

Diagnosing lupus requires putting together several clues — symptoms, physical exam findings, blood tests, and sometimes a skin biopsy. No single test confirms lupus. Your dermatologist may look for specific patterns on the skin and order blood tests like ANA (antinuclear antibody) and anti-dsDNA antibodies, which are elevated in most lupus patients.

Treatment Options

  • Sun protection: Daily broad-spectrum SPF 30+ sunscreen and sun-protective clothing are essential — UV exposure worsens both the rash and disease activity.
  • Antimalarial drugs: Hydroxychloroquine (Plaquenil) is the cornerstone of lupus treatment. It reduces flares, protects against organ damage, and treats the butterfly rash.
  • Topical corticosteroids: Help calm active skin inflammation during flares.
  • Topical calcineurin inhibitors: Tacrolimus or pimecrolimus for facial skin to avoid steroid side effects.
  • Systemic medications: More severe disease may require immunosuppressants or biologic therapies managed with a rheumatologist.

When to See a Dermatologist

  • You have a persistent red rash across your cheeks and nose that doesn't go away
  • Your rash worsens after sun exposure
  • You have joint pain, fatigue, and a facial rash together
  • You have been diagnosed with lupus and are developing new skin changes
  • Round, scarring patches appear on your scalp or face

Frequently Asked Questions

Is the butterfly rash always present with lupus?

No. Only about 30–50% of lupus patients develop the butterfly rash, and it comes and goes with disease activity. Some people with lupus never get this rash. The absence of the rash does not rule out lupus.

Can the butterfly rash leave scars?

The classic malar (butterfly) rash usually does not scar. However, a related condition called discoid lupus can cause permanent scarring and hair loss if not treated early. If you develop thick, scaly patches on your face or scalp, see a dermatologist promptly.

Does sunscreen really make a difference?

Yes — significantly. UV exposure is one of the strongest triggers for lupus skin flares and can even worsen internal organ involvement. Daily sunscreen use (SPF 30 or higher, broad-spectrum) is one of the most important things you can do to manage lupus.

Do I need to see both a dermatologist and a rheumatologist?

Often, yes. A dermatologist manages the skin manifestations of lupus, while a rheumatologist oversees systemic disease and internal organ protection. Both specialties frequently collaborate to give you the best care.
