What should you know about dark burn mark?

After a burn heals, the affected skin may remain darker because inflammation has changed pigment activity. The area can also be lighter, dry, sensitive, or uneven in texture. A mark that is still hot, tender, wet, blistered, or expanding may indicate that the injury has not settled. Burning skin without a clear burn can occur with contact dermatitis, rosacea, or shingles, particularly when there is a rash, sensitivity, or one-sided pattern.

Appearance alone cannot confirm the cause. The timing, exposure, depth of the injury, and whether the skin surface is intact all guide the assessment.

Cool a recent minor burn with cool running water, remove tight items near swelling, and cover the area with a clean non-stick dressing. Do not apply ice, burst blisters, peel skin, or use fragranced products on healing skin. Once the surface has closed, protect it from sunlight with clothing or a suitable sunscreen to limit further darkening. Stop any product that stings and arrange a review if the mark keeps burning or does not improve.

Get urgent care for a large, deep, white or charred burn, burns involving the face, hands, genitals, major joints, or a chemical or electrical injury. Seek prompt advice for increasing redness, warmth, swelling, pus, fever, severe pain, new blisters, or a rash with grouped blisters or one-sided pain.

Ask whether the skin is fully healed, whether the mark fits post-inflammatory pigmentation or an active rash, which dressing or moisturiser is suitable, and when pigment-focused treatment can be considered without irritating the skin.
