Bad sunburn peeling: what to do

Do not pull away loose skin or scrub the area. Cool it gently, apply a plain fragrance-free moisturiser, drink fluids, and prevent further sun exposure while it heals.

Ultraviolet injury damages cells in the outer skin layer. The body releases those injured cells, so flaking may begin after the redness and heat have started to settle. The exposed skin beneath can feel tight, tender, dry, or itchy.

Peeling does not remove the underlying sun damage, and deliberately exfoliating will not speed safe healing. Blisters indicate a deeper burn and should remain intact because their covering helps shield the raw surface from irritation and infection.

Take a cool shower or place a clean, cool damp cloth over the area; avoid ice directly on skin. Pat dry, then smooth on an unperfumed moisturiser without rubbing. Wear loose, soft clothing and keep the burn covered from sunlight.

If an edge catches on clothing, leave it alone rather than tearing it. Avoid fragranced products, exfoliating acids, retinoids, scrubs, and hot water until the surface is comfortable and intact. A pharmacist or clinician can help check whether a pain reliever is suitable for you.

Seek prompt medical advice for extensive blistering, severe or worsening pain, marked swelling, fever, chills, dizziness, confusion, vomiting, faintness, or difficulty drinking. A burn involving the face, eyes, genitals, hands, or a large body area also deserves assessment.

Increasing warmth, spreading redness, pus, an unpleasant smell, or worsening tenderness after the initial burn may signal infection. Babies, young children, older adults, and people with significant medical conditions can become unwell or dehydrated more easily.

Ask whether the blistered or peeling area needs a dressing, which moisturiser is least likely to sting, and whether your medicines or health conditions change which pain relief you can use. If the skin looks infected, ask whether it needs cleaning, a swab, or prescription treatment.
