How Lupus Affects Your Skin: Causes, Symptoms, and Treatments

Introduction

Lupus, an autoimmune disease, often causes various skin problems that can be distressing. Whether you have systemic lupus erythematosus (SLE) or cutaneous lupus, understanding the signs and treatments can help manage flare-ups and prevent long-term skin damage.

Common Skin Manifestations of Lupus

1. Butterfly Rash (Malar Rash)

   • A red, butterfly-shaped rash spreading across the nose and cheeks.

   • Triggered or worsened by UV exposure.

2. Photosensitive Rashes

   • Red, scaly, or ring-shaped rashes on sun-exposed areas like arms, shoulders, and neck.

   • Known as subacute cutaneous lesions.

3. Discoid Lesions

   • Coin-shaped sores, often on the face, scalp, or inside the mouth.

   • Can lead to scarring and permanent hair loss if untreated.

4. Mucosal Ulcers

   • Painful sores inside the mouth, nose, or genital areas.

5. Raynaud's Phenomenon

   • Fingers and toes turning red, white, or blue in response to cold or stress.

6. Livedo Reticularis

   • Bluish, lace-like patterns under the skin, especially on the legs.

Treatment Options for Lupus Skin Issues

1. Topical Corticosteroids

   • Reduce inflammation and control rashes.

   • Available as creams, gels, or injections for deeper lesions.

2. Antimalarial Medications

   • Hydroxychloroquine (Plaquenil) and Chloroquine (Aralen) help reduce immune system overactivity.

3. Calcineurin Inhibitors

   • Tacrolimus (Protopic) and Pimecrolimus (Elidel) to manage small patches of rashes.

4. NSAIDs (Nonsteroidal Anti-inflammatory Drugs)

   • Help alleviate inflammation and discomfort.

5. Immunosuppressive Therapies

   • For severe cases, medications to suppress the immune system may be prescribed.

Preventing Lupus-Related Skin Flare-Ups

• Sun Protection: Use broad-spectrum sunscreen (SPF 30+), wear protective clothing, and avoid peak sun hours.

• Vitamin D Supplementation: Especially if sun exposure is limited.

• Avoid Smoking: Smoking can worsen lupus symptoms and reduce medication efficacy.
