Run cool (not cold) water over a hot water burn for 10 to 20 minutes as soon as it happens. This is the single most important step you can take, and it works best when started within the first few minutes of the injury. What you do after cooling depends on how deep the burn is and how much skin it covers.
Cool the Burn Immediately
Hold the burned area under cool running tap water for a full 10 to 20 minutes. The water should feel comfortable, not icy. Cold water or ice can damage already-injured tissue and actually slow healing. If running water isn’t available, a cool, clean wet cloth held against the skin is a reasonable alternative, though less effective.
While cooling the burn, remove any clothing or jewelry near the area before swelling starts. If fabric is stuck to the skin, don’t pull it off. Once you’ve cooled the burn, gently pat the area dry with a clean cloth.
Skip the butter, toothpaste, oil, or any other home remedy you may have heard about. These trap heat in the skin and increase the risk of infection.
How to Tell How Serious It Is
Hot water scalds generally fall into three categories based on how deep the damage goes:
- Superficial (first-degree): Only the top layer of skin is affected. The area looks red (or red-tinged on darker skin tones) and may peel like a sunburn. These hurt but heal on their own.
- Partial-thickness (second-degree): The burn extends into the second layer of skin. You’ll see blisters, color or texture changes beyond simple redness, and noticeable pain. These need more careful wound care.
- Full-thickness (third-degree): All skin layers are destroyed, sometimes reaching the fat underneath. The skin may look white, ashen gray, or charred black. Because the nerve endings are destroyed, full-thickness burns often don’t hurt, which can be misleading. These always need professional treatment.
Most kitchen and bathroom scalds from hot water, coffee, or tea are superficial or partial-thickness. Full-thickness burns from hot water are less common but can happen with prolonged contact, especially in young children or elderly adults who can’t move away quickly.
When the Burn Needs Emergency Care
Not every scald needs a hospital visit, but some do. Get medical help right away if the burn covers a large area. National hospital guidelines flag partial or full-thickness burns covering more than 10% of an adult’s body surface (roughly the size of one arm) or more than 5% of a child’s body surface as needing specialized burn care. A burn covering more than 20% of an adult’s body or 10% of a child’s body is classified as a major burn and a medical emergency.
Location matters too. Burns on the hands, feet, face, groin, or over a joint need professional evaluation regardless of size, because scarring in these areas can limit movement or cause complications. The same goes for burns that wrap all the way around a limb or finger, since swelling beneath tight burned skin can cut off circulation.
Any burn that looks white, gray, or waxy rather than red should be seen by a professional, even if it doesn’t hurt. The absence of pain in a burn is not a good sign.
Caring for a Minor Burn at Home
For small superficial or partial-thickness burns that don’t meet the criteria above, home treatment works well. After cooling and drying the burn, apply a thin layer of an over-the-counter antibiotic ointment. A combination ointment containing bacitracin and polymyxin B (sold as Polysporin) is widely used for minor burns and works on both superficial and some partial-thickness injuries.
Cover the ointment with a non-stick dressing or fine mesh gauze. Regular dry gauze on its own is a poor choice because it promotes scab formation and tends to stick painfully to the wound. Non-stick pads, foam dressings, or hydrogel sheets all work better. Change the dressing once a day, or sooner if it gets wet or dirty, reapplying ointment each time.
What to Do About Blisters
Blisters are common with partial-thickness scalds, and the instinct to pop them is strong. The right approach depends on the blister’s size and location. Small, firm blisters under about 6 millimeters (roughly the size of a pencil eraser) are best left alone. They act as a natural barrier against infection and help control pain.
Large, thin-walled blisters bigger than 6 millimeters are more likely to burst on their own, which raises the infection risk. These are generally better off being carefully drained and the loose skin removed, a process called “deroofing.” Blisters on fingertips, palms, or the soles of the feet can also limit your ability to use the hand or walk, so they may need to be drained for comfort and mobility. If a blister has already ruptured, gently clean the area, remove the loose dead skin, apply antibiotic ointment, and cover it with a fresh non-stick dressing.
If you’re unsure about handling a blister, especially a large one, having it managed at a clinic reduces the chance of introducing bacteria.
Managing Pain
Burns hurt, and the pain often peaks in the first 24 to 48 hours. Over-the-counter pain relievers are effective for minor scalds. Ibuprofen (Advil, Motrin) and naproxen (Aleve) both reduce pain and inflammation, which makes them a good first choice. Acetaminophen (Tylenol) works for pain but doesn’t address swelling. Aspirin is another option for adults, but it should not be given to children under 2 or anyone 18 or younger who has or is recovering from chickenpox or flu. Follow the dosage directions on the package.
Keeping the burn elevated above your heart when possible also helps reduce throbbing. Cool compresses (not ice) can provide short-term relief between dressing changes.
Healing Timeline
Superficial burns typically heal within a week to 10 days without scarring. The skin peels, new skin forms underneath, and the redness gradually fades.
Partial-thickness burns take longer, generally two to three weeks for shallower ones. Deeper partial-thickness burns can take three to six weeks or more and are more likely to leave a scar. Keeping the wound moist with ointment and covered with a proper dressing speeds healing and reduces scar formation compared to letting the burn dry out and scab over.
Full-thickness burns do not heal well on their own because the skin’s regenerative layer has been destroyed. These typically require skin grafting and leave permanent scars.
Watching for Infection
Infection is the main complication to watch for with any burn you’re treating at home. Check the burn daily when you change the dressing. Signs that something is wrong include oozing pus or fluid that looks cloudy or discolored, red streaks spreading outward from the wound, increasing pain after the first couple of days (instead of improving), warmth and swelling that gets worse, and a fever above 103°F (39°C). Any of these warrant a call to your doctor or a trip to urgent care. Caught early, burn infections respond well to treatment. Left alone, they can turn a minor injury into a serious one.
Reducing Long-Term Scarring
Once a partial-thickness burn has fully closed, the scar is still maturing for months. Keeping the new skin moisturized helps it stay soft and flexible. Silicone-based scar sheets or gels, available over the counter, can flatten and soften raised scars when worn consistently over several weeks. Protecting the healed area from sun exposure for at least a year is also important, as new scar tissue burns and discolors easily. A high-SPF sunscreen or clothing coverage works well for this.
For burns on joints or areas that move a lot, gentle stretching as the wound heals helps prevent the scar from tightening and restricting your range of motion. If a scar does become tight or raised despite these measures, options like pressure garments, laser treatment, or physical therapy can help, but starting prevention early gives you the best outcome.
