Swollen face after sunburn: what to know

Ultraviolet exposure injures the outer skin and triggers inflammation. Fluid moving into the inflamed tissue can make the face, eyelids, or other exposed areas look puffy, alongside redness, warmth, tenderness, and later peeling. The visible reaction may become clearer after the exposure rather than immediately.

Blisters suggest a deeper burn and should not be opened. Sunburn can also cause headache, nausea, feverishness, weakness, or dehydration, particularly after prolonged heat and sun exposure. Repeated exposure contributes to sun-damaged skin over time.

Move indoors or into shade, drink fluids, and use a cool damp cloth or cool shower on the skin. Apply a bland moisturiser or emollient gently while the skin is intact. Wear loose clothing and protect the area from more sun until it has healed. Avoid ice directly on skin, scrubbing, peeling flakes, or breaking blisters.

A pharmacist or clinician can advise on pain relief or treatment for a more inflamed burn. Do not apply topical corticosteroids to the face unless a clinician specifically recommends the product and instructions.

Seek prompt care for extensive blistering, severe pain, marked facial or eye swelling, eye pain, vision changes, pus, spreading warmth, or fever. Get urgent help for confusion, faintness, repeated vomiting, inability to drink, or trouble breathing. A burn affecting an infant, older adult, or person with a significant medical condition also deserves early advice.

Ask whether the burn needs examination, which moisturiser is suitable, how to protect healing skin, and whether any facial treatment should be paused. Ask about warning signs of infection or dehydration and how to prevent another sunburn.
