Cool running water is the single best thing to put on a hot water burn, and you should apply it immediately for at least 15 minutes. After cooling, a thin layer of petroleum jelly or aloe vera protects the skin while it heals. What you do in those first minutes matters more than any ointment you apply later, so getting the sequence right is important.
Cool the Burn First
Hold the burned area under cool (not cold) running water for a minimum of 15 minutes. Keep going longer if the pain hasn’t eased. If you don’t have access to a tap, cool bottled water works. This step does two things: it pulls heat out of the deeper layers of skin that are still cooking even after the hot water is gone, and it reduces swelling that leads to further tissue damage.
While you’re cooling the burn, gently remove any clothing or jewelry near the area before swelling starts. If fabric is stuck to the skin, leave it in place and cool around it.
Avoid ice, ice water, or anything extremely cold. These can cause additional skin and tissue damage on top of the burn itself. Cool water is effective. Cold water makes things worse.
What to Apply After Cooling
Once the burn has been thoroughly cooled, apply a thin layer of petroleum jelly or aloe vera. That’s it. The ointment keeps the skin moist, which helps new cells grow and prevents the wound from cracking as it heals. You don’t need an antibiotic ointment for a minor burn. Some antibiotic creams can actually trigger an allergic reaction on damaged skin.
Do not apply cream, lotion, oil, cortisone, butter, or egg white. These are all common instincts that interfere with healing.
Cover It With the Right Dressing
After applying ointment, cover the burn with a nonstick dressing or bandage. Regular gauze can bond to the raw skin underneath as it dries, which tears new tissue off every time you change it. Look for gauze pads that come pre-coated with petroleum jelly, or apply your ointment to the pad before placing it on the burn, ointment-side down. Many pharmacies carry nonprescription burn dressings designed for this purpose.
Change the dressing daily, or whenever it gets wet or dirty. Each time, gently clean the area, reapply a thin layer of petroleum jelly or aloe vera, and cover with a fresh nonstick pad.
Managing Pain
Minor hot water burns hurt, sometimes intensely for the first day or two. Over-the-counter pain relievers like ibuprofen and acetaminophen are effective for superficial burns. Ibuprofen has the added benefit of reducing inflammation, which can help with swelling around the burned area. Follow the dosing instructions on the package.
Home Remedies That Make Burns Worse
Butter, toothpaste, milk, flour, and eggs are among the most commonly suggested home remedies for burns, and all of them are harmful. Butter and oil trap heat in the skin. Toothpaste contains detergents, abrasives, and sugar-based ingredients that irritate open wounds and promote bacterial growth. Mint-flavored toothpaste intensifies the burning sensation. Flour and egg whites introduce bacteria directly into damaged tissue.
How to Tell if Your Burn Needs Medical Care
Not all hot water burns are the same, and recognizing the severity helps you decide what to do next.
A first-degree burn looks like a sunburn: dry, red, and painful. The damage stays in the outermost layer of skin. These heal on their own with the cooling, ointment, and dressing steps above.
A second-degree burn goes deeper. The skin looks wet and red, blisters form, and the pain is more intense. Shallow second-degree burns can often be managed at home if they’re small, but deeper ones (where the skin looks less moist and the pain is oddly reduced) need professional treatment. Don’t pop blisters. They’re a natural sterile barrier protecting the raw skin underneath.
A third-degree burn destroys the full thickness of the skin. It may look white, brown, black, or waxy, and the area can feel surprisingly painless because the nerves are destroyed. This always requires emergency care.
Regardless of the degree, seek medical attention if the burn covers a large area (more than about 10% of an adult’s body, or 5% of a child’s), or if it’s on the hands, feet, face, joints, or groin. Burns that wrap all the way around an arm, leg, or finger also need urgent care because swelling can cut off circulation. For children and older adults, err on the side of getting burns evaluated, since their skin is thinner and more vulnerable to deeper damage.
Signs of Infection During Healing
As your burn heals over the coming days, watch for increasing redness spreading outward from the edges, green or foul-smelling discharge, increasing pain after the first couple of days (when pain should be decreasing), or fever. Any of these suggest the wound has become infected and needs medical treatment. Keeping the burn clean, covered, and moisturized with petroleum jelly is the most reliable way to prevent infection in the first place.
