First Aid for Burns: Essential Steps to Treat and Heal Burn Injuries

Second-degree burns and all burn injuries need the right first aid fast. This guide covers exactly how to treat first, second, and third-degree burns at home, when to see a doctor, and when to call 911.

When to Call 911

In some cases, burn injuries require immediate medical attention. Call 911 if:

• The burn penetrates all layers of the skin

• The skin appears leathery or charred, with white, brown, or black patches

• The person is an infant or a senior

• Severe burns of certain areas such as the face, hands, and genitals will require emergency medical evaluation

Initial Steps for All Burns

1. Stop the Burning Process: Put out the fire or stop the person's contact with hot liquid, steam, or other material. If clothing is on fire, help the person "stop, drop, and roll" to smother the flames. Remove smoldering material and hot or burned clothing. If clothing sticks to the skin, cut or tear around it.

2. Remove Constrictive Clothing: Take off jewelry, belts, and tight clothing immediately, as burns can swell quickly.

First-Degree Burns (Affecting Top Layer of Skin)

1. Cool the Burn: Hold the burned skin under cool (not cold) running water or immerse in cool water until the pain subsides. Use compresses if running water isn't available.

2. Protect the Burn: Cover the burn with a sterile, non-adhesive bandage or clean cloth. Avoid applying butter, oil, lotions, or creams, especially if they contain fragrance. Apply a petroleum-based ointment two to three times per day.

3. Treat Pain: Give over-the-counter pain relievers such as acetaminophen, ibuprofen, or naproxen.

4. When to See a Doctor: Seek medical help if you notice signs of infection (increased pain, redness, swelling, fever, or oozing), the person needs a tetanus or booster shot, the burn blister is larger than two inches or oozes, redness and pain last more than a few hours, the pain worsens, or the hands, feet, face, or genitals are burned.

5. Follow Up: The doctor will examine the burn and may prescribe antibiotics and pain medication.

Second-Degree Burns: Symptoms and Treatment

Second degree burns damage the top two layers of skin (the epidermis and dermis), causing deep redness, swelling, blistering, and intense pain. They often look wet or shiny. Here's how to treat a second degree burn:

1. Cool the Burn: Immerse the burn in cool water for 10 to 15 minutes. Use compresses if running water isn't available. Don't apply ice, as it can lower body temperature and cause further pain and damage. Avoid breaking blisters or applying butter or ointments, which can lead to infection.

2. Protect the Burn: Cover the burn loosely with a sterile, nonstick bandage and secure it in place with gauze or tape.

3. Prevent Shock: Unless the person has a head, neck, or leg injury, or it would cause discomfort, lay the person flat, elevate their feet about 12 inches, and elevate the burn area above heart level, if possible. Cover the person with a coat or blanket.

4. See a Doctor: The doctor can assess burn severity, prescribe antibiotics and pain medications, and administer a tetanus shot, if needed.

How to Treat a Burn at Home: What You Need to Know

Most minor burns — including small first-degree burns and some superficial second-degree burns — can be safely managed at home with the right steps. Here's what our doctors recommend for effective burn treatment at home.

Cool it quickly. Run cool (not cold) water over the burned area for 10–20 minutes as soon as possible after the injury. This reduces tissue damage and relieves pain. Never use ice, ice water, or frozen items — extreme cold can damage skin further and cause the burn to deepen.

Keep it clean. Gently clean the burned area once or twice a day with mild soap and water. Pat dry with a clean cloth. Avoid scrubbing. Keeping the wound clean is the single most important thing you can do to prevent infection during healing.

Protect the wound. Cover the burn with a sterile non-stick bandage or clean dressing. Change it daily or whenever it becomes wet or dirty. For second degree burns with intact blisters, leave blisters alone — they form a natural barrier against infection. If a blister breaks on its own, clean the area and apply a thin layer of antibiotic ointment before re-covering.

Manage pain. Over-the-counter pain relievers like ibuprofen or acetaminophen can help control burn pain and reduce inflammation. Take them as directed on the label. Keeping the burn elevated above heart level when possible also helps reduce swelling and throbbing pain.

Watch for signs of infection. A healing burn should gradually become less painful and red over several days. See a doctor right away if you notice increasing pain, expanding redness, yellow or green discharge, a foul odor, fever, or swollen lymph nodes near the burn. These are signs of infection that need prompt treatment.

Support healing with moisture. Once the initial wound has closed (usually after a few days), applying a fragrance-free moisturizer or aloe vera gel can help keep the skin hydrated and reduce itching as it heals. Sun protection is also important — healing burn skin is extra sensitive to UV damage and can darken or scar more easily with sun exposure.

Know when home treatment isn't enough. Burns larger than 3 inches, burns on the face, hands, feet, genitals, or joints, and any burn that doesn't improve within two weeks need professional evaluation. Our AI doctor can help you assess whether your burn needs in-person care — get a fast, free evaluation any time.

Third-Degree Burns

1. Call 911

2. Protect the Burn Area: Cover the burn loosely with a sterile, nonstick bandage or, for large areas, a sheet or other material that won't leave lint in the wound. Separate burned toes and fingers with dry, sterile dressings. Do not soak the burn in water or apply ointments or butter, as this can cause infection.

3. Prevent Shock: Unless the person has a head, neck, or leg injury, or it would cause discomfort, lay the person flat, elevate their feet about 12 inches, and elevate the burn area above heart level, if possible. Cover the person with a coat or blanket. For an airway burn, do not place a pillow under the person's head when lying down, as this can close the airway. Have a person with a facial burn sit up. Check pulse and breathing to monitor for shock until emergency help arrives.

4. See a Doctor: Doctors will provide oxygen and fluid, if needed, and treat the burn.

Remember, prevention is key when it comes to burn injuries. Always exercise caution when handling hot objects, liquids, or chemicals, and keep a well-stocked first aid kit on hand. If you're unsure about the severity of a burn or how to treat it, don't hesitate to seek professional medical advice from a healthcare provider or burn specialist.

The Bottom Line

The golden rule for thermal injuries is immediate water cooling for 10-15 minutes while removing constrictive items before swelling occurs. Recognize when emergency care is needed—burns covering large areas, electrical injuries, or those affecting critical body parts require professional medical attention.
