For most minor burns, cool running water is the single most important treatment, and it works best when applied immediately. Run cool (not cold) water over the burn for at least 20 minutes. After that, the right topical treatment depends on how deep the burn is, but a simple layer of petroleum-based ointment or aloe vera gel and a non-stick bandage will handle the majority of everyday kitchen and household burns.
Cool Water First, Everything Else Second
The 20-minute rule matters more than any ointment you apply afterward. As soon as a burn happens, hold the affected area under cool, running water for a full 20 minutes. This reduces the temperature of damaged tissue, limits how deep the injury spreads, and significantly cuts down on pain. The water should feel comfortable, not cold. Ice, ice water, and frozen packs can actually increase tissue damage by constricting blood flow to skin that’s already injured.
If you can’t get to a faucet, a cool wet cloth can substitute temporarily, but running water is more effective because it continuously draws heat away. Don’t skip or shorten this step. Twenty minutes sounds long when you’re in pain, but cooling is the single intervention with the strongest evidence behind it for reducing burn severity.
How to Tell What You’re Dealing With
What you put on a burn depends on its depth. Most burns you’ll treat at home fall into the first two categories below.
First-degree burns damage only the outermost layer of skin. They look like a sunburn: dry, red, painful, no blisters. These typically heal within two weeks without scarring.
Superficial second-degree burns reach into the deeper layers of skin. They’re moist, red, extremely painful, and form blisters. These also heal on their own, though more slowly. Deep second-degree burns are less painful (because nerve endings are damaged), less moist, and slower to heal. They often scar.
Third-degree burns destroy the full thickness of skin and may appear white, black, brown, or red. They can feel less painful than you’d expect because the nerves are destroyed. These always require professional medical care.
What to Apply After Cooling
Once you’ve cooled the burn for 20 minutes, gently pat the area dry with a clean cloth. For first-degree burns and small superficial second-degree burns, you have a few good options:
- Petroleum jelly (Vaseline): A thin layer keeps the wound moist, which is the environment skin needs to rebuild itself. It doesn’t contain irritating additives and is inexpensive. Reapply when you change your bandage.
- Aloe vera gel: Pure aloe vera gel has clinical support for speeding up healing. In one study, second-degree burns treated with aloe vera reached full skin regrowth in 11 days compared to the typical 14 days. Apply a thin layer and reapply with each dressing change. Look for products with minimal added fragrances or alcohol, which can sting.
- Antibiotic ointment: A thin layer of over-the-counter antibiotic ointment can help prevent infection on small burns. This is especially useful if the burn is in a spot prone to friction or dirt exposure.
There is no single “best” topical agent for burns. Even in clinical settings, experts haven’t reached consensus on which product is optimal. For minor burns at home, keeping the wound clean and moist is what matters most.
How to Bandage a Burn
After applying your chosen ointment, cover the burn with a non-stick dressing. Standard gauze can adhere to a healing wound and tear new skin when you remove it. Non-stick options include fine mesh gauze, silicone-coated pads, or foam dressings, all available at pharmacies. Secure the dressing loosely with medical tape or a rolled bandage.
Change the dressing based on how much fluid the wound produces. A burn that’s oozing may need a new dressing once or twice a day. A drier burn can go longer between changes. The goal is to manage moisture without pulling off the new skin growing underneath. Each time you change the dressing, gently wash the burn with mild soap and water, pat dry, and reapply ointment before covering it again.
Managing Pain
Burns hurt, and first-degree and superficial second-degree burns are often the most painful because the nerve endings are intact and exposed to irritation. Over-the-counter pain relievers like ibuprofen or acetaminophen, taken by mouth, are your first line for managing that pain.
For topical relief, look for products containing lidocaine or pramoxine, both of which are FDA-approved numbing agents for minor burns. These come in creams, sprays, and gels, and can be applied up to three or four times a day. One caution: avoid using numbing products on large areas of skin, blistered burns, or raw open wounds, as too much absorption can cause side effects.
What Not to Put on a Burn
Several popular home remedies actively make burns worse. Toothpaste is one of the most common mistakes. It contains sodium fluoride, which irritates damaged skin, along with compounds like glycerol that can actually serve as a growth medium for bacteria. Mint-based toothpaste adds insult to injury by intensifying the burning sensation. Butter and cooking oils trap heat in the skin and create a breeding ground for infection. Egg whites, flour, and milk carry the same contamination risk.
Ice and ice water are also harmful. While the instinct to cool a burn with something very cold makes sense, temperatures below cool can constrict blood vessels and cause additional tissue damage on top of the thermal injury. Stick with comfortable, cool running water.
When a Burn Needs Medical Attention
Not every burn can be safely managed at home. The American Burn Association recommends immediate medical evaluation for any full-thickness (third-degree) burn, any partial-thickness burn covering roughly 10% or more of your body surface, and any deep burn involving the face, hands, feet, genitalia, or skin over a joint. Burns with other injuries, poorly controlled pain, or burns in someone with chronic health conditions also warrant professional care.
Even a small burn that initially seems minor can develop an infection. Watch for these warning signs in the days after the injury: pain that gets significantly worse instead of better, pus or cloudy fluid leaking from the wound, skin redness or discoloration spreading beyond the edges of the burn, and a foul smell coming from the burn site. Any of these signals that bacteria have taken hold and you need medical treatment.
Burns are also classified as “dirty wounds” for tetanus purposes. If your last tetanus booster was five or more years ago, or if you’re unsure of your vaccination history, a burn is a good reason to get one.
A Simple At-Home Routine
For a typical minor burn (a cooking splash, a curling iron contact, a small scald), the full routine looks like this: cool under running water for 20 minutes, gently dry, apply a thin layer of petroleum jelly or aloe vera, cover with a non-stick bandage, and take ibuprofen or acetaminophen if the pain is bothersome. Change the dressing once or twice daily, washing gently each time. Most first-degree burns heal within two weeks. Superficial second-degree burns take longer but follow the same basic care pattern.
Leave blisters intact when possible. They’re a natural sterile bandage protecting the new skin forming underneath. If a blister breaks on its own, clean the area, apply ointment, and cover it with a fresh dressing.
