Run your hand under cool water immediately and keep it there for at least 20 minutes. That single step does more to limit damage and reduce pain than anything else you can do at home. The sooner you start cooling, the better: cool running water is effective when applied within the first three hours after a scald, but the first few minutes matter most. Here’s everything else you need to know to treat the burn properly and heal without complications.
Cool the Burn Right Away
Turn on the tap to a comfortable cool temperature, around 15°C (59°F), and hold your hand under the stream for a full 20 minutes. This feels like a long time, especially once the initial panic fades, but shorter cooling leaves residual heat trapped in deeper skin layers, which continues causing damage even after the hot water is gone. Use a timer on your phone so you don’t cut it short.
While your hand is under the water, gently remove any rings, bracelets, or watches. Burned skin swells quickly, and jewelry can become painfully tight or cut off circulation if you wait too long.
What Not to Put on a Burn
Skip ice, ice water, butter, toothpaste, and any greasy home remedy. Ice is harsh enough to damage already-injured skin, making the burn worse. Butter and other greasy substances trap heat against the skin, slowing the release of warmth and deepening the injury. Toothpaste can introduce irritants and bacteria into an open wound. Stick with plain cool running water.
Figure Out How Serious It Is
Once you’ve cooled the burn, take a close look at the skin. What you see tells you whether you can manage this at home or need medical care.
A first-degree burn affects only the outermost layer of skin. It looks red (or shows a color change on darker skin tones), feels painful, and has no blisters. Think of a mild sunburn. These heal on their own in 3 to 6 days.
A second-degree burn goes deeper and damages the second layer of skin. You’ll likely see blisters forming, and the skin may look wet or moist with red, white, or splotchy patches. Pain can be intense. These burns typically heal in 1 to 3 weeks but need careful wound care to avoid infection and scarring.
A third-degree burn reaches through all skin layers and sometimes into the fat or muscle beneath. The skin may appear white, waxy, leathery, brown, or black, and it can feel stiff. Because nerve endings are destroyed, there may be surprisingly little pain. This always requires emergency medical treatment.
When You Need Medical Attention
Not every scald needs a trip to the emergency room, but certain burns do. Get medical help if:
- The burn covers an area larger than your palm
- Blisters are large or widespread
- The skin looks white, waxy, leathery, or charred
- The burn wraps around your fingers or crosses a joint like the wrist or knuckles
- You’re under 10 or over 50 years old, as skin in these age groups is more vulnerable
Burns on the hands are taken more seriously than burns on, say, the forearm, because the complex tendons and joints in your hand are at higher risk of scarring that limits movement. If you have any doubt, err on the side of getting it checked.
Treating a Minor Burn at Home
After cooling, gently pat the area dry with a clean cloth. Apply a thin layer of petroleum jelly to the burned skin. This keeps the wound moist, which speeds healing and helps prevent thick or raised scars. Don’t use antibiotic ointments unless a doctor recommends one, as they can cause allergic reactions in some people.
Cover the burn with a non-stick bandage or gauze pad. Regular adhesive bandages can stick to the damaged skin and tear it when removed. Silicone-coated dressings (Mepitel is one common brand) are designed to lift off painlessly. Change the dressing daily or whenever it gets wet or dirty, reapplying petroleum jelly each time.
If you have blisters, leave them intact. They act as a natural sterile bandage protecting the raw skin underneath. A popped blister is an open door for bacteria.
Managing Pain
Scald burns hurt, especially second-degree ones. Over-the-counter pain relievers like ibuprofen (Advil, Motrin) or acetaminophen (Tylenol) are effective. Ibuprofen has the added benefit of reducing inflammation and swelling, which can help with comfort in the first few days. Follow the dosing instructions on the label. Don’t give aspirin to anyone under 18.
Keeping the burn elevated above your heart when you’re resting also reduces throbbing. Prop your hand on a pillow while sitting or sleeping.
Watch for Signs of Infection
Even well-cared-for burns can get infected, and catching it early makes a big difference. Over the next several days, check the wound each time you change the dressing. Warning signs include:
- Increasing redness, warmth, or swelling spreading beyond the edges of the original burn
- Worsening pain or new tenderness after the burn had been improving
- Cloudy or foul-smelling discharge
- Discoloration of the wound turning dark brown, blue, or black
- Fever or chills
Any of these signs warrant a call to your doctor or a visit to urgent care. Burn infections can progress quickly because the skin’s protective barrier is already compromised.
Helping Your Skin Heal With Less Scarring
First-degree burns rarely scar. Second-degree burns can leave marks, but proper aftercare makes a noticeable difference. Continue applying petroleum jelly to the healing skin until it has fully closed over. Wounds that dry out and form scabs take longer to heal and produce thicker scars.
Once the skin has sealed, switch your focus to sun protection. New skin is especially sensitive to UV light, and sun exposure can darken the scar and slow fading. Apply a broad-spectrum sunscreen with SPF 30 or higher to the area whenever it will be exposed to sunlight. This is worth doing for at least a year after the burn, since the scar tissue continues remodeling during that time.
Keeping the new skin moisturized also helps. Healed burn skin tends to be dry and tight, and regular moisturizer improves flexibility and comfort as the area matures. If your scar feels raised, itchy, or restricts the movement of your fingers, a doctor can discuss options like silicone sheets or pressure garments that help flatten scar tissue over time.
