For a fresh burn, the single best thing you can do is run cool water over it for at least 10 minutes, ideally 20. After cooling, apply pure aloe vera gel or a thin layer of petroleum jelly, then cover with a non-stick bandage. What you put on a burn depends on its severity, so the first step is figuring out what you’re dealing with.
Cool Water First, Everything Else Second
Before you reach for any ointment or cream, cool the burn under running water. This is the most important treatment you can give yourself. The American Red Cross recommends cool or cold running water for a minimum of 10 minutes, with 20 minutes being ideal. Don’t stop at a quick rinse. Burns continue damaging deeper layers of tissue even after the heat source is gone, and sustained cooling limits that damage.
A few rules here: don’t use ice, ice packs, or ice water. These can worsen the injury by constricting blood flow and damaging tissue further. If running water isn’t available, a clean, cool, damp cloth works as a substitute. And avoid cooling for longer than 40 minutes, which raises the risk of hypothermia, especially in children or older adults.
How to Tell if Your Burn Needs a Doctor
What you put on a burn at home only applies to minor burns. Anything more serious needs professional care, and it’s worth taking 30 seconds to assess before you start treating.
- First-degree burns affect only the outermost layer of skin. They’re red, dry, and painful, like a sunburn. These heal on their own with basic home care.
- Second-degree burns go deeper. The skin looks red, white, or splotchy, blisters form, and pain can be severe. Shallow second-degree burns can be treated at home if they’re small. Deep ones may scar.
- Third-degree burns destroy all layers of skin and sometimes the fat beneath it. The skin may look white, brown, black, or leathery. Paradoxically, these burns may not hurt much because the nerves are destroyed. They always require emergency medical care.
Any burn wider than about 3 inches (8 centimeters) needs medical attention. So does any burn on the face, hands, feet, groin, or over a joint. If you have blisters wider than 2 inches that aren’t healing within two weeks, that also warrants a visit.
What to Apply After Cooling
Once you’ve cooled the burn thoroughly, pat the area dry gently with a clean cloth. Then you have a few good options for what goes on the skin.
Aloe vera gel is one of the best-studied home treatments for minor burns. A review of four clinical trials covering 371 patients found that burns treated with aloe vera healed nearly 9 days faster on average than those treated without it. Look for pure aloe vera gel without added fragrances, dyes, or alcohol. If you have an aloe plant, the gel straight from the leaf works well. Apply a thin layer directly to the burn.
Petroleum jelly (like Vaseline) is another solid choice. It keeps the wound moist, which is what damaged skin needs to regenerate. Unlike antibiotic ointments, petroleum jelly rarely causes allergic reactions. Apply a thin layer and reapply when you change the bandage.
For burns that are seen by a healthcare provider, they may use a prescription silver-based cream, which is the most common clinical burn dressing. But for minor burns at home, aloe vera or petroleum jelly is effective and safe.
How to Bandage a Burn
After applying your gel or ointment, cover the burn with a non-stick gauze pad. Regular gauze or cotton can stick to the raw skin and tear new tissue when you remove it. Non-stick wound pads are available at any pharmacy, often labeled as “non-adherent” dressings.
Wrap the pad loosely with rolled gauze or medical tape. The goal is to protect the burn from friction and bacteria, not to compress it. Change the dressing once a day, or whenever it gets wet or dirty. Each time, gently clean the area, reapply aloe or petroleum jelly, and cover with fresh gauze.
Leave Blisters Alone
If your burn develops blisters, don’t pop them. The fluid inside a blister acts as a natural sterile barrier that protects the raw skin underneath from bacteria. Popping a blister opens the door to infection and slows healing. If a blister breaks on its own, gently clean the area with water and apply petroleum jelly before re-bandaging.
Managing Burn Pain
Burns hurt, and the pain from a second-degree burn can be intense for the first few days. Over-the-counter pain relievers help significantly. Ibuprofen works well because it reduces both pain and inflammation. Acetaminophen is an alternative if you can’t take ibuprofen. Taking them on a regular schedule rather than waiting for pain to spike keeps discomfort more manageable.
Cool compresses (not ice) applied over the bandage can also provide short-term relief between doses.
What Not to Put on a Burn
Some of the most common home remedies for burns actually make things worse. Butter, cooking oil, coconut oil, and toothpaste all trap heat in the skin, increase irritation, and raise infection risk. The Mayo Clinic specifically warns against all of these. Egg whites, honey (unless medical-grade, which is different from what’s in your pantry), and essential oils also don’t belong on a fresh burn.
Skip the ice. Skip the cotton balls. And don’t apply adhesive bandages directly to burned skin.
Signs of Infection to Watch For
Even with good care, burns can get infected. Watch for these changes in the days after your injury: increasing redness that spreads beyond the burn’s edges, green or yellow discharge, worsening pain after the first 48 hours (when it should be improving), swelling that gets worse rather than better, or a fever. A burn that hasn’t shown clear signs of healing within two weeks also needs professional evaluation.
Keeping the wound clean, changing dressings daily, and resisting the urge to touch the burn with unwashed hands are the simplest ways to prevent infection from setting in.
