TL;DR
Acute cutaneous lupus (ACLE) is a form of lupus, an autoimmune disease in which the immune system attacks the body’s own tissues — in this case, the skin. Most people with ACLE develop a butterfly-shaped (malar) rash across the nose and cheeks that looks like a sunburn, often after sun exposure. It is common in people who also have systemic lupus erythematosus (SLE) — about 2 in 3 people with SLE have cutaneous lupus symptoms. There is no cure, but medications help about 60% of people with cutaneous lupus, and since 40%–70% of flare-ups follow UV exposure, daily sun protection is the most powerful self-care tool.
Quick Answer
What it is: Acute cutaneous lupus is a type of lupus — an autoimmune disease — in which the immune system attacks the skin, causing sudden (acute) rashes that often appear in response to sun exposure.
The hallmark sign: Most people with ACLE develop a butterfly-shaped rash across the nose and cheeks (a malar rash) that looks like a sunburn; rashes also occur on arms or legs after sun exposure.
How common it is: About 2 in 3 people who have systemic lupus (SLE) also have cutaneous lupus symptoms, and cutaneous lupus is generally most common in women ages 20 to 50.
The outlook: ACLE is lifelong with no cure, but most people get symptom relief with treatment — about 60% respond to medication, and daily sun protection (SPF 30+, avoiding midday sun, protective clothing) prevents most flare-ups.
What the research says
Acute cutaneous lupus responds best to antimalarials. A meta-analysis of 31 studies (1,990 treatment courses) found that 91% of patients with acute cutaneous lupus improved on hydroxychloroquine or chloroquine, compared with 63% across all cutaneous lupus subtypes. (Chasset et al., British Journal of Dermatology, 2017).
Smoking blunts the benefit of treatment. In 10 studies with 1,398 patients, smokers had about half the odds of skin improvement on antimalarials (OR 0.53) compared with nonsmokers. (Chasset et al., Journal of the American Academy of Dermatology, 2015).
What Is Acute Cutaneous Lupus?
Lupus is an autoimmune disease in which the body attacks itself. One form is cutaneous lupus erythematosus (CLE) — "cutaneous" refers to the skin. CLE is an autoimmune disease in which the immune system attacks the skin, producing sores or lesions on the face, nose, and cheeks.
Acute cutaneous lupus (ACLE) means the rashes appear suddenly (acutely), often in response to sun exposure. Most people with ACLE develop a butterfly rash across their face.
There is no cure for ACLE. However, treatment can reduce the frequency and severity of symptom flare-ups.
What Is Lupus, and How Does ACLE Fit In?
The most common type of lupus is systemic lupus erythematosus (SLE). In SLE, the immune system attacks other organs in addition to the skin — such as the kidneys, heart, lungs, and joints. Almost three out of every four people who have lupus have SLE.
SLE causes widespread inflammation, which may be acute (sudden) or chronic (long-lasting). People with lupus often have:
Common Lupus Symptom | Description |
Fatigue | Overwhelming, persistent tiredness |
Joint pain or swelling | Inflammatory joint involvement |
Rashes or other skin symptoms | Including the butterfly rash of ACLE |
People may have one type of lupus, such as SLE or CLE. But more often, they have multiple types at the same time.
What Are the Types of Cutaneous Lupus?
There are three major types of cutaneous lupus, and each produces a different skin rash:
Type | Rash Appearance | Typical Location |
Acute cutaneous lupus | Butterfly-shaped rash that looks like a sunburn | Nose and cheeks |
Discoid lupus | Coin-shaped, thick, dark/red patches | Cheeks, ears, nose |
Subacute cutaneous lupus | Ring-shaped lesions | Arms, chest, back, neck |
Who Gets Acute Cutaneous Lupus, and How Common Is It?
Acute cutaneous lupus is common in people who also have systemic lupus (SLE). Cutaneous lupus is generally most common in women ages 20 to 50.
The numbers worth knowing:
Statistic | Value |
People with lupus who have SLE | Almost 3 in 4 |
People with SLE who also have cutaneous lupus symptoms | About 2 in 3 |
People with lupus who have only cutaneous lupus | Around 1 in 10 |
People whose lupus flares after UV light exposure | About 40% to 70% |
What Causes Acute Cutaneous Lupus?
Experts do not know exactly what causes acute cutaneous lupus. Some people get the butterfly rash as their first sign of SLE — before they are ever diagnosed with systemic lupus.
Lupus and other autoimmune diseases may run in families. You may have a higher risk of developing lupus if you are:
Risk Factor | Note |
Female | Cutaneous lupus most often affects women ages 20–50 |
Aged 15 to 44 | The highest-risk age range |
Black, Asian American, Hispanic/Latino, or Native American | Elevated risk across these populations |
What Are the Symptoms of Acute Cutaneous Lupus?
For most people, acute cutaneous lupus appears as a butterfly-shaped rash across the nose and cheeks. Another name for this rash is a malar rash (rash on the cheeks). It typically looks like a sunburn and usually doesn’t hurt — but it may itch.
People may also get rashes on their arms or legs. These rashes often appear after sun exposure, although they are not a sunburn. Importantly, ACLE skin rashes do not scar — but after they go away, the skin may look lighter or darker than before.
Acute cutaneous lupus may also cause:
Additional Symptom | Description |
Canker sores | Painful sores in the mouth |
Hives | Raised, painful bumps |
Temporary hair loss | Hair loss during active disease |
Skin color changes | Skin looks lighter or darker where the rash was — without scarring |
What Are Symptom Flare-Ups?
People with ACLE experience symptom flare-ups. This means they do not have symptoms all the time; instead, symptoms come and go after exposure to triggers such as stress or too much sunlight.
How Is Acute Cutaneous Lupus Diagnosed?
A dermatologist (a doctor specializing in skin) or a rheumatologist (a doctor specializing in arthritis) may diagnose acute cutaneous lupus.
Sometimes the provider performs a skin test called a biopsy. During a biopsy, the dermatologist removes a small skin sample and sends it to a laboratory for examination under a microscope. By looking at the sample this way, providers can tell whether a skin rash is due to acute cutaneous lupus or another condition.
How Is Acute Cutaneous Lupus Treated?
Depending on symptom severity, a healthcare provider may recommend medications. These medications do not cure lupus, but they can reduce symptoms and flare-ups. Some research suggests that medications are helpful for about 60% of people with cutaneous lupus.
Medication Class | Examples | What It Does |
Topical steroid ointments | Fluocinolone acetonide (Synalar), hydrocortisone butyrate (Locoid) | Reduce swelling and inflammation |
Anti-inflammatory drugs | Dapsone (Aczone), low-dose methotrexate (Otrexup, Rasuvo) | Reduce pain and swelling |
Antimalarial drugs | Hydroxychloroquine (Plaquenil) | Fight fatigue, reduce rashes, decrease joint pain |
Calcineurin inhibitors | Tacrolimus (Protopic, Prograf), pimecrolimus (Elidel) | Decrease inflammation by suppressing the immune system |
How Can Flare-Ups Be Prevented?
About 40% to 70% of people with lupus have symptom flare-ups after exposure to ultraviolet (UV) light. To minimize flare-ups, people with lupus need to take extra caution around sunlight and artificial light.
Sun-Protection Step | Detail |
Daily sunscreen | Broad-spectrum sunscreen with at least SPF 30, every day |
Timing | Avoid sunlight when the sun is strongest — 10 a.m. to 4 p.m. |
Tanning beds | Do not use them |
Indoor lighting | Limit time around fluorescent lights |
Protective clothing | Wide-brimmed hats and long sleeves |
What Is the Outlook?
Acute cutaneous lupus is a lifelong condition. Most people experience symptom relief with treatment. You will need to take extra precaution around UV rays to avoid flare-ups.
Lupus itself cannot be prevented — but if you have lupus, you can avoid symptom flare-ups by identifying and avoiding triggers. Beyond sun avoidance, these habits help:
Daily Habit | Why It Helps |
Nutritious diet | Fruits, vegetables, and whole grains support overall health |
Moderate exercise | As often as possible |
Stress management | Healthy coping tools reduce stress-triggered flares |
Sleep | At least seven to eight hours per night |
Take medications as prescribed | Consistency keeps symptoms controlled |
Quit smoking | Smoking can make the rash worse and may make rash medications less effective |
Conclusion
Acute cutaneous lupus is the skin face of lupus: an autoimmune condition in which the immune system turns against the skin, announcing itself most memorably as a butterfly-shaped rash across the nose and cheeks. It arrives suddenly, often after sunlight, and it rarely comes alone — about two in three people with systemic lupus carry cutaneous symptoms. There is no cure, and it is lifelong. But the prognosis for daily life is far better than that: most people achieve symptom relief, medications help about 60% of people with cutaneous lupus, and because 40% to 70% of flare-ups follow UV exposure, a disciplined sun-protection routine does much of the work that medicine cannot.
CTA: If you notice a rash that looks like a sunburn across your nose and cheeks — especially one that appears after time in the sun — schedule an appointment with a dermatologist or rheumatologist, because the butterfly rash can be the first sign of systemic lupus before any other diagnosis. Ask about a skin biopsy, ask which medications fit your symptoms, and start today’s most effective self-care habit: broad-spectrum SPF 30 sunscreen, applied every day.

Frequently Asked Questions
What is acute cutaneous lupus?
Acute cutaneous lupus (ACLE) is a type of lupus, an autoimmune disease in which the body attacks itself. In ACLE, the inflammation affects the skin: rashes appear suddenly (acutely), often in response to sun exposure. Most people with ACLE develop a butterfly rash across their face. There is no cure, but treatment can reduce the frequency and severity of flare-ups.
What does the acute cutaneous lupus rash look like?
For most people, ACLE appears as a butterfly-shaped rash across the nose and cheeks — called a malar rash — that typically looks like a sunburn. It usually does not hurt but may itch. Rashes can also appear on the arms or legs after sun exposure. The rashes do not scar, but the skin may look lighter or darker after the rash fades.
Is acute cutaneous lupus a form of lupus?
Yes. Lupus is an autoimmune disease, and the most common type is systemic lupus erythematosus (SLE), in which the immune system attacks organs such as the kidneys, heart, lungs, and joints as well as the skin. Almost three out of four people with lupus have SLE, and about two in three people with SLE also have cutaneous lupus symptoms.
Who is most likely to get acute cutaneous lupus?
Cutaneous lupus is generally most common in women ages 20 to 50. Risk is higher for people who are female, aged 15 to 44, or Black, Asian American, Hispanic/Latino, or Native American. The condition is common in people who also have systemic lupus, and lupus and other autoimmune diseases may run in families.
What triggers a flare-up of acute cutaneous lupus?
Symptoms come and go in flare-ups after exposure to triggers such as stress or too much sunlight. About 40% to 70% of people with lupus have symptom flare-ups after exposure to ultraviolet (UV) light — so sun avoidance and sun protection are central to preventing flares.
How is acute cutaneous lupus diagnosed?
A dermatologist or rheumatologist may diagnose ACLE based on symptoms and exam. Sometimes a skin biopsy is performed: a small skin sample is removed, sent to a laboratory, and examined under a microscope to determine whether the rash is due to acute cutaneous lupus or another condition.
Can acute cutaneous lupus be prevented or cured?
There is no cure, and lupus itself cannot be prevented — but flare-ups can be largely prevented by avoiding triggers: broad-spectrum SPF 30+ sunscreen every day, avoiding sunlight between 10 a.m. and 4 p.m., never using tanning beds, limiting fluorescent lighting, wearing sun-protective clothing, sleeping seven to eight hours, exercising moderately, managing stress, taking medications as prescribed, and stopping smoking.
