Lupus rashes are a common symptom for people with different types of lupus, but they are most common in cutaneous lupus (skin lupus). They can develop anywhere on the body and are often uncomfortable and irritating.

We created this guide to help you understand lupus rashes, including the different types, potential triggers, and treatment options.

What is lupus rash?

Skin rashes are a common symptom of lupus.

During a lupus flare-up, the immune system attacks healthy cells in the skin, causing rash symptoms like blisters, bumps, redness, and irritation.

Lupus rashes can occur anywhere on the body, but they are most common on the face, arms, back, hands, and neck.

Not everyone with lupus develops a rash, and symptoms can vary from person to person. Some people find that rashes worsen during flare-ups or after certain triggers, such as sun exposure.

Tracking when rashes appear, how long they last, and possible triggers can help you spot patterns and share clearer information with your doctor when discussing treatment options.

Types of lupus rash

People with lupus can develop different rashes depending on the type of lupus they have.

People with cutaneous lupus, for example, have a higher risk of developing skin symptoms due to inflammation that affects the skin.

Some of the most common types of lupus rash include:

Malar (butterfly) rash

The malar rash is the most common rash in people with lupus. It affects about half of all people with the condition.

A malar rash typically appears on the face, reaching from cheek to cheek across the nose. It’s sometimes shaped like a butterfly, which explains why this type of rash is often called “a butterfly rash.”

However, it’s also possible to get a malar rash on the upper arms, shoulders, chest, and hands.

They are often red in color and can be itchy and painful. They can last for days or weeks at a time, often for the duration of a flare.

Discoid lupus rash

Discoid lupus is a form of cutaneous (skin) lupus, meaning it mainly affects the skin. It’s the most common type of chronic cutaneous lupus.

Discoid lupus rash is usually seen on the scalp and face and is named for the disc-shaped patches it causes.

In most cases, discoid lupus rashes:

• Are itchy (although not everyone experiences itchiness)
• Are not painful
• Are circular or coin-shaped
• Present as red, thick, and scaly patches
• Can cause permanent scars or skin discoloration

Because discoid lupus rashes affect the scalp, they can damage hair follicles, causing temporary or permanent hair loss. The extent of hair loss depends on how severe and long-lasting the rash is.

Subacute cutaneous lupus erythematosus rash

A subacute cutaneous lupus erythematosus rash (SCLE) is red and ring-shaped. It primarily causes sores and scaly patches with a distinct edge, giving the appearance of a set of small interlocking circles.

SCLE rashes are photosensitive, meaning they often develop or worsen after sun exposure—particularly on areas of the skin exposed to sunlight (back, chest, arms).

Experiences differ, but in most cases, an SLCE rash:

• Comes on quickly
• Is not itchy
• Is not painful
• Does not leave permanent scarring, but may cause long-lasting discoloration

SLCE can be triggered by medications used to treat systemic lupus erythematosus (SLE), the most common type of lupus. Symptoms may develop some time after starting a new medication, and tracking both symptoms and treatments can help identify possible links.

Acute cutaneous lupus erythematosus rash

Acute cutaneous lupus erythematosus (ACLE) rash typically appears when SLE is more active during a flare.

This type of rash primarily affects the face, arms, legs, and trunk of the body. It often comes on quickly, doesn’t last long, and doesn’t leave permanent scars.

ACLE rashes can be localized or generalized. The malar (butterfly) rash is a localized form that appears across the cheeks and bridge of the nose. Generalized ACLE rashes are more widespread and can affect larger areas of the body.

Depending on how the rash presents, symptoms may include:

• Bumpy and patchy skin
• Skin discoloration (pink or red)
• A painful, burning sensation
• Scaly skin patches

In some cases, additional symptoms such as mouth sores (canker sores) or temporary hair loss may occur.

Other types of lupus rash

• Chillblain lupus rash is patchy, itchy, and often painful. It affects different areas of the body and often develops after exposure to cold or wet temperatures.

• Lupus erythematosus timidus rash presents with raised plaques with bumps across the body. They often cause skin discoloration, but don’t usually leave permanent skin changes after they heal.

• Lupus panniculitis targets the deeper layers of the skin. In some cases, it can cause painful, deep ulcers, which lead to permanent skin scarring and indentations when healed.

• Neonatal lupus erythematosus rash only affects newborns born to people who experienced a lupus flare during pregnancy. It can cause the baby’s skin to be discolored, often with circular shapes. It primarily affects the head, face, and neck.

Lupus rash causes

Because lupus is an autoimmune condition, symptoms often develop when something triggers the immune system, causing it to become too active. This is known as a flare-up.

In most cases, rashes develop quickly and resolve after the flare-up subsides.

Some of the most common triggers for lupus rashes include:

• Sun exposure
• Smoking
• Birth control pills
• Infections
• Certain medications
• Emotional stress
• Air pollution
• Fatigue
• Contact with heavy metals like lead or cadmium
• Ultra-processed foods

How to treat lupus rash

The most effective treatment depends on your condition, symptoms, and specific type of rash. For example:

• Topical or oral corticosteroids
• Corticosteroid injections (for more persistent or thick patches)
• Antimalarial medications (which can help reduce rashes and prevent flares over time)
• Topical treatments, such as tacrolimus ointment
• Immunosuppressive medications, such as methotrexate or mycophenolate mofetil
• Biologic medications (targeted immune treatments)
• Other medications, such as retinoids or certain antibiotics (such as dapsone), which may help reduce inflammation in some cases

Connect your skin symptoms to the bigger picture

Despite their prevalence, lupus rashes can be a very stressful and potentially debilitating effect of living with the condition. For many people with lupus, managing and preventing lupus rashes is a key part of maintaining quality of life.

The key to reducing lupus rash symptoms is learning about your body and reducing your exposure to potential triggers. Using the Human Health app, you can log flares alongside potential triggers, like sun exposure, and see what patterns emerge. You get clear reports to share with your doctor, so they can better personalize your care.

Frequently asked questions

How do I know if my rash is lupus?

Not all skin rashes are caused by lupus. The following signs may indicate your rash is lupus-related:

• Persistence: Lupus rashes often come on during flare-ups and can last for weeks at a time.

• Itchiness: Some lupus rashes are itchy. If you have an itchy rash, see a doctor to identify possible causes.

• Trigger source: A common trigger for lupus rash is exposure to sunlight. If your rash appeared after direct UV exposure, it may be caused by lupus.

Does the sun make lupus rash worse?

Yes, many people with lupus notice a rash after sun exposure. UV light is known to be a common trigger.

If you have lupus, avoiding direct sun exposure can help reduce your risk of a flare-up.

What’s the difference between lupus and rosacea?

Rosacea is a chronic skin condition that primarily affects the face.

Lupus is an autoimmune condition that causes symptoms and rashes across the entire body.

While both can cause redness and a rash on the face, rosacea symptoms are often more gradual and don’t affect other areas of the body.
