Sunburn scar treatment: what to know

Healing after sunburn can leave a flat red, brown or lighter patch. A true scar is more likely when the skin's structure has changed, for example as a depression or raised area. The appearance, skin tone, depth of the original burn, blistering and any picking all affect the assessment.

Treating active irritation too aggressively can prolong the problem. A clinician first checks that the skin barrier has recovered and considers other causes of a persistent mark. Sunburn and Sun-Damaged Skin provide useful background on the injury and prevention.

Keep the area comfortable with gentle cleansing and a bland moisturiser or emollient. Protect it from direct sun with shade, clothing and appropriate protection on intact skin. Avoid picking, tanning, scrubs and unprescribed bleaching agents while the appearance is changing.

Once the skin is calm, a dermatologist may discuss options matched to the finding, such as treatment for inflammation or pigment, or procedures for selected textural scars. The choice depends on location, skin sensitivity and risk of further colour change. Do not use a topical corticosteroid on the face or broken skin without specific advice.

Seek prompt care for infection signs, severe pain, extensive blistering, eye involvement, major swelling, fever, faintness or confusion. Book a dermatology assessment for a mark that is raised, indented, painful, itchy, bleeding, changing, or not gradually settling after the burn has healed.

Ask what type of change is present, when treatment should begin, which options suit your skin tone, how many appointments might be needed, and what aftercare reduces irritation or pigment change. Share any previous reactions to creams, peels or light-based treatment.
