When are topical corticosteroids recommended for sunburn?

Sunburn is an injury caused by ultraviolet exposure. A steroid may reduce inflammation, but it does not reverse the skin injury or protect against further sun exposure. Some burns are deeper than they first appear, and broken or blistered skin needs careful handling. A healthcare professional should decide whether a steroid is appropriate, especially when the affected area is extensive or symptoms are severe.

Move out of the sun, cool the skin with a lukewarm shower or cool damp cloth, and drink fluids. Apply a gentle moisturiser while the skin is intact, avoid picking or bursting blisters, and protect the area from further sunlight. Do not apply steroid to blistered, broken or infected skin unless instructed. A pharmacist or clinician can help choose suitable pain relief for you.

Seek prompt care for large or extensive blistering, severe pain, dehydration symptoms, faintness, confusion, fever, vomiting or signs of infection such as spreading redness and pus. Get urgent advice for sunburn involving the eyes, face with swelling, hands, or genitals, and for a burn in a young child or someone medically vulnerable. Arrange review if healing is not progressing or pain is worsening.

Ask whether the burn needs examination, which products are safe on the affected skin, how to protect blisters, and which warning signs should bring you back for care.
