how long does sunburn last

Most mild sunburns heal in about 3–5 days, while more severe burns can take 7–14 days for the redness, pain, and peeling to fully settle down.

How long does sunburn last?

Quick Scoop

• Mild sunburn: usually 3–5 days of redness and soreness, with some light peeling near the end.

• Moderate sunburn: about 1 week, often with more swelling, heat, and noticeable peeling.

• Severe or blistering sunburn: 10 days to around 2 weeks for the skin to recover on the surface, sometimes longer.

• Redness often peaks within 12–24 hours, then slowly fades over several days.

• Even when the burn “looks” healed, deeper UV damage to the skin cells can last for years and increases future skin cancer risk.

Mini timeline: what to expect

• First 3–5 hours: Redness and warmth start to show up after the sun exposure.

• 12–24 hours: Redness and pain peak; skin can feel tight, hot, and very sensitive.

• Days 2–3: Pain usually starts to ease; skin may feel itchy or tight.

• Days 3–7: Peeling often starts around day 3 as the damaged top layer sheds.

• Days 7–14: Moderate to severe burns with blisters can take up to 2 weeks to fully settle.

A quick example: if you fall asleep on the beach without sunscreen and wake up bright red and sore that night, you’ll probably feel worst the next day, start peeling around day 3, and look mostly normal by the end of the week if the burn is mild to moderate.

Factors that change how long it lasts

• How intense and how long the UV exposure was (midday sun, high altitude, reflective surfaces like water or snow all increase dose).

• Skin type (lighter skin usually burns faster and more severely, but all skin tones can burn and be damaged).

• Whether there were blisters (blistering burns are more severe and last longer).

• Age, medications, and health conditions that make skin more sensitive to UV.

• How quickly you cool, moisturize, and protect the burned skin afterward (good aftercare can ease symptoms, but it can’t undo the damage).

Quick at‑home care (and when to worry)

For mild to moderate sunburn, common advice includes:

1. Cool the skin: brief cool showers or compresses (not ice directly on the skin).

2. Moisturize: fragrance‑free moisturizers or aloe to help with dryness and peeling.

3. Pain relief: over‑the‑counter anti‑inflammatories like ibuprofen or acetaminophen if you can take them safely (follow package or doctor instructions).

4. Hydrate: drink more fluids because burns can dehydrate you.

5. Protect: keep the burned area out of the sun (clothing, shade, avoiding tanning).

See a doctor or urgent care quickly if you notice:

• Large or numerous blisters, especially on the face, hands, feet, or over joints.

• Fever, chills, nausea, confusion, or feeling very unwell (possible sun poisoning or heat illness).

• Signs of infection: worsening redness, pus, streaks, or increasing pain in one area.

Short‑term vs long‑term effects

• Short term: redness, pain, swelling, blisters, and peeling, usually resolving in days to a couple of weeks depending on severity.

• Long term: repeated burns raise the risk of skin cancers (like melanoma and squamous cell carcinoma) and speed up skin aging (wrinkles, spots, rough texture).

If your sunburn feels unusually painful, is on a large area, or isn’t improving after several days, it’s safest to get it checked by a healthcare professional.

TL;DR: Most sunburns last under a week, but bad, blistering burns can hang around up to two weeks, and every burn adds to your lifetime skin damage.
