If you’ve noticed a red, scaly patch on your face or scalp that won’t go away, it could be discoid lupus. This form of lupus shows up mainly on the skin and can look like stubborn acne or eczema. The good news is you don’t have to live with it—there are practical steps you can take right now.
Discoid lupus, also called chronic cutaneous lupus, is an autoimmune skin condition. Your immune system mistakenly attacks healthy skin cells, causing inflammation and damage. The spots usually start as flat, round plaques that may be pink or brown, often with a raised border. Over time they can become thick, scar‑like, and sometimes cause hair loss if they affect the scalp.
Typical signs include itching, burning, or tenderness at the site. Sun exposure makes the rash worse, so many people notice flare‑ups after being outdoors. While discoid lupus mainly stays on the skin, a small percentage of patients later develop systemic lupus erythematosus (SLE), which can affect internal organs.
The first line of defense is protecting your skin from UV light. Use a broad‑spectrum sunscreen with at least SPF 30 every day, even when it’s cloudy. Wear hats and UPF clothing if you’ll be outside for long periods. Sunscreen can dramatically cut down flare‑ups.
Topical treatments are often enough for mild cases. Prescription creams that contain corticosteroids or calcineurin inhibitors (like tacrolimus) help reduce inflammation quickly. Apply the medication to clean, dry skin once or twice a day as your doctor advises.
If the rash is more stubborn, oral medications may be needed. Antimalarial drugs such as hydroxychloroquine are standard because they calm the immune system without strong side effects. Your doctor will monitor blood work regularly while you’re on these meds to catch any issues early.
Beyond medicines, everyday habits matter. Keep your skin moisturized with fragrance‑free creams; dry skin can worsen itching and cracking. Avoid harsh soaps, scrubbing brushes, or anything that irritates the rash. If a lesion is bleeding or infected, see a dermatologist promptly to prevent scarring.
Finally, watch for warning signs of systemic involvement: persistent fatigue, joint pain, fever, or swelling in other parts of your body. Early detection lets you get the right treatment before complications arise.
