Sunburn on a scar: what to know

Scar tissue can have a different texture, pigment pattern, and sensitivity from nearby skin. Ultraviolet exposure may trigger heat, tenderness, redness, swelling, blistering, or later peeling across the scar and surrounding area. A healed scar can also develop temporary colour change after inflammation. A fresh wound, raised scar, or recently treated area may be especially reactive, so cover it and follow the specific advice given by your clinician. Read about [Sunburn](/conditions/sunburn/) and [Sun-Damaged Skin](/conditions/photoaging/) for related information.

Move out of direct sun and cool the area with a clean, cool damp cloth. Do not put ice directly on the skin, scrub the scar, peel loose skin, or open blisters. Apply a bland moisturiser or discuss [Emollient Therapy](/treatments/medical-dermatology/emollient-therapy/) with a pharmacist or clinician. Wear loose clothing that does not rub, and keep the scar covered from further sunlight once the skin can tolerate it. Avoid new cosmetic or active products until the skin settles.

Arrange medical advice if the scar becomes increasingly painful, warm, swollen, or wet, or if blisters are extensive, recurrent, or slow to settle. Seek prompt care for fever, marked weakness, confusion, faintness, breathing difficulty, or inability to drink. A clinician can distinguish sunburn from infection or another inflammatory problem; do not start [Topical Corticosteroids](/treatments/medical-dermatology/topical-corticosteroids/) on a damaged scar without advice.

Ask whether the scar’s age and type change the recommended dressing or moisturiser, whether its colour should be monitored after healing, and when sunscreen or silicone-based scar care can resume.
