Most sunburns heal in about 3 to 7 days, but more severe burns can take up to 10–14 days for the skin to fully recover.

Quick Scoop: Healing Timeline ⏱

How long it takes for a sunburn to heal depends on how bad it is:

  • Mild sunburn
    • Light redness, mild soreness.
    • Heals in about 3–5 days.
  • Moderate sunburn
    • Red, painful, may swell and peel.
    • Usually heals in about 5–7 days, sometimes up to a week.
  • Severe sunburn
    • Very red, very painful, often with blisters; may feel sick (fever, chills, nausea).
    • Can take 7–10 days, and sometimes up to 2 weeks to fully heal.

Peeling often starts around day 3 as your body sheds damaged skin, and that can last several days even after the pain improves.

What “healed” really means

On the surface, a sunburn seems “healed” once:

  • Redness fades.
  • Pain and burning are gone.
  • Blisters (if any) have dried and new skin has formed.

This usually fits in the 3–14 day window depending on severity. But the deeper DNA damage to skin cells lasts much longer and adds up over the years, increasing skin cancer risk even when the burn looks healed on the outside.

Simple at‑home care that speeds comfort

You can’t truly “cure” a sunburn overnight, but you can make healing smoother:

  • Cool (not ice‑cold) compresses or cool showers to ease heat.
  • Aloe vera gel or gentle, fragrance‑free moisturizer to soothe and limit peeling.
  • Drink plenty of water so your body has enough fluid to repair skin.
  • Avoid more sun on the area; cover up until it is fully healed.
  • Don’t pop blisters or peel skin—this increases infection risk and slows healing.

When to see a doctor

Get medical help right away if:

  • You have large or many blisters, especially on the face, hands, or genitals.
  • You feel very unwell: fever, chills, confusion, nausea, vomiting, or signs of dehydration (dry mouth, dizziness, dark urine).
  • The burn isn’t improving after a week or looks infected (increasing redness, pus, worsening pain).

Mini FAQ (forum‑style)

“I got burned at the beach yesterday. When will it stop hurting?”

  • Mild burn: expect peak redness and pain within 24 hours, then gradual improvement over the next few days.
  • Most people feel a lot better by day 3–4, even if peeling continues a bit longer.

“Can a bad sunburn really last two weeks?”

Yes. Deep, blistering burns (often from being out all day with no protection) can take up to about 14 days to fully settle.

TL;DR:
Mild sunburn: 3–5 days; moderate: about a week; severe: 7–14 days, with peeling and tenderness sometimes lasting on the longer side. Always protect healing skin from more sun to avoid deeper, lasting damage.
