What should you know about slight sunburn?

Sunburn is an inflammatory skin reaction after ultraviolet exposure. Mild cases may cause [Skin Redness](/symptoms/skin-redness/), warmth, tightness, tenderness, or sensitivity, and the full reaction can become clearer after the exposure. Peeling may follow as the damaged outer skin sheds. Repeated exposure contributes to [Sun-Damaged Skin](/conditions/photoaging/), so a mild episode is a useful reason to review daily protection rather than continue tanning.

Move out of direct sun, cool the skin with a tepid shower or cool damp cloth, and drink fluids normally. Apply a bland moisturiser or [Emollient Therapy](/treatments/medical-dermatology/emollient-therapy/) while the skin feels dry, and avoid picking peeling skin or breaking blisters. Wear loose clothing and protect the area from further exposure until it settles. Do not apply ice directly to the skin.

Seek medical advice for [Skin Blisters](/symptoms/skin-blisters/), extensive peeling, severe pain, marked swelling, signs of infection, or a burn involving the eyes, face, hands, or genitals. Urgent care is appropriate for confusion, faintness, repeated vomiting, difficulty breathing, or inability to keep fluids down. A clinician can advise whether treatment such as [Topical Corticosteroids](/treatments/medical-dermatology/topical-corticosteroids/) is suitable; do not self-start it on broken skin.

How extensive is the burn? What can I safely apply? Do any medicines I take increase sun sensitivity? How should I protect the area while it heals? Which symptoms mean I should return or seek urgent care?
