For a minor burn, the best thing to put on it is a thin layer of petroleum jelly or aloe vera after cooling the area under running water for about 10 minutes. That cooling step comes first and matters more than anything you apply afterward. Once the burn is cool and dry, a simple ointment protects the damaged skin, keeps it moist, and helps it heal faster.
Cool the Burn First
Before you put anything on a burn, run cool water over it for about 10 minutes. This is the single most important step. Use cool water, not cold. Cold water or ice can actually make a burn injury worse by constricting blood flow and further damaging the tissue. Just let a gentle stream of room-temperature or slightly cool tap water flow over the area.
Skip the urge to grab ice cubes, frozen peas, or anything from the freezer. After 10 minutes of cooling, gently pat the area dry with a clean cloth.
What to Apply on a Burn
Once the burn is cooled, apply a thin layer of petroleum jelly (like Vaseline) or pure aloe vera gel. That’s it. The ointment doesn’t need to contain antibiotics. In fact, some antibiotic ointments can trigger allergic reactions and cause more irritation on already damaged skin. A plain, simple barrier ointment is the safest choice.
If a blister has already broken on its own, gently clean the area with water and a little liquid soap, then apply an antibiotic ointment. If you notice a rash developing around the area, stop using the antibiotic ointment and switch to plain petroleum jelly.
After applying ointment, you can loosely cover the burn with a non-stick bandage to protect it from rubbing against clothing or getting dirty. Don’t wrap it tightly. The goal is light protection, not compression.
What Not to Put on a Burn
Several popular home remedies actually slow healing or increase infection risk. Do not apply any of the following:
- Butter or cooking oil: These trap heat in the skin and create a breeding ground for bacteria.
- Ice or cold water: Extreme cold damages tissue further and can worsen the injury.
- Toothpaste: Contains chemicals that irritate raw skin and can introduce infection.
- Egg whites: Carry a risk of bacterial contamination on broken skin.
- Lotions, creams, or cortisone: These are not designed for burn wounds and can interfere with healing.
Leave Blisters Intact
If your burn develops blisters, don’t pop them. Blisters form a natural sterile barrier that protects the raw skin underneath from bacteria. Breaking them deliberately opens the door to infection. If a blister breaks on its own, clean it gently, apply ointment, and cover it with a loose bandage.
How Burns Heal
Knowing what type of burn you have helps you understand what to expect. First-degree burns, like a typical sunburn, affect only the surface layer of skin. They look dry and red, feel painful, and generally heal within a week with basic care.
Second-degree burns go deeper and damage the second layer of skin. These are the ones that blister, weep fluid, and hurt intensely. They typically heal within one to three weeks, though deeper second-degree burns take longer because fewer structures remain to regenerate new skin.
Third-degree burns destroy the full thickness of the skin. They can appear white, black, brown, or deep red, and they feel dry. Surprisingly, they’re often less painful than second-degree burns because the nerve endings in the skin have been destroyed. These burns always need professional medical treatment.
Managing Pain at Home
Minor burns can throb for hours or even days. Over-the-counter anti-inflammatory pain relievers like ibuprofen help reduce both pain and swelling. Taking one shortly after the burn occurs, rather than waiting until the pain becomes severe, tends to keep discomfort more manageable. Keeping the burn moisturized with petroleum jelly also reduces the tight, stinging sensation that develops as damaged skin dries out.
Burns That Need Medical Attention
Not every burn can be managed at home. Seek medical care for burns that are deep, larger than a few inches across, or located on the hands, feet, face, groin, buttocks, or over a major joint. Burns covering more than 10% of the body’s surface area may require transfer to a specialized burn center.
Burns also fall into the category of wounds that can require a tetanus booster. If your last tetanus shot was five or more years ago, or if you’re unsure of your vaccination history, a burn injury is a reason to get one. The CDC classifies burns alongside crush injuries and wounds with dead tissue as higher-risk for tetanus.
Signs of infection to watch for in the days after a burn include increasing pain instead of improving pain, spreading redness beyond the burn’s edges, fever, and any foul-smelling drainage. These warrant a visit to a healthcare provider rather than continued home care.
