A second-degree burn damages the top layer of skin and the layer beneath it. You can treat many of these burns at home, but some need medical care. The right approach depends on the size, location, and depth of the burn. Cool the burn immediately, keep it clean, and watch for signs of infection.
What Is a Second-Degree Burn?
A second-degree burn, also called a partial-thickness burn, goes through the epidermis and into the dermis. The dermis contains blood vessels, nerve endings, and hair follicles. This is why these burns hurt more than first-degree burns.
You will see redness, swelling, and blistering. The skin often looks wet or shiny. Blisters may form within minutes or hours. The area is painful and sensitive to touch and air.
First-degree burns only affect the top layer of skin. They are red and painful but do not blister. Third-degree burns go through all layers of skin and may look white, black, or leathery. They can be less painful because nerve damage has occurred.
How To Treat 2nd Degree Burn Immediately
The first minutes matter. Run cool — not cold — water over the burn for 10 to 15 minutes. Cool water lowers the skin temperature and stops the burning process from continuing into deeper tissue.
Do not use ice. Ice can damage the skin further and cause frostbite on top of the burn. Do not use butter, oils, or toothpaste. These home remedies trap heat and increase the risk of infection.
Remove tight items like rings or bracelets near the burn. The area may swell quickly, and removing these later is harder. Do not pop blisters. Blisters protect the raw skin underneath and reduce infection risk.
After cooling, gently pat the area dry with a clean cloth. Apply a thin layer of antibiotic ointment or petroleum jelly. Cover with a sterile, non-stick gauze bandage. Change the dressing daily or whenever it becomes wet or dirty.
When To See a Doctor for a Second-Degree Burn
Some second-degree burns need professional care. See a doctor if the burn is larger than about 3 inches in diameter. Burns on the face, hands, feet, genitals, or major joints also need medical evaluation.
Burns that cross a joint — like the elbow or knee — can limit movement as they heal. A doctor may recommend physical therapy or a special dressing. Burns on the face can affect breathing if there was smoke inhalation. Burns on the hands or feet can cause long-term function problems if not treated properly.
Seek immediate emergency care if the burn looks charred or has white or brown patches. This suggests a deeper burn. Also get emergency help if the person has trouble breathing, seems confused, or the burn came from electricity or chemicals.
People with diabetes, weakened immune systems, or poor circulation should see a doctor for any second-degree burn. These conditions slow healing and raise infection risk.
How Long Does a Second-Degree Burn Take To Heal?
Most second-degree burns heal within 2 to 3 weeks. The timeline depends on the depth of the burn and your overall health. Superficial second-degree burns that only slightly enter the dermis heal faster than deep ones.
New skin forms from the edges of the burn and from hair follicles in the dermis. You may notice the area looks pink or red for months after the burn closes. This is normal. The color gradually fades over time.
Pain usually decreases after the first few days. Over-the-counter pain relievers like acetaminophen or ibuprofen can help. Take them as directed on the package. If the burn becomes more painful instead of less, that is a warning sign of infection.
Scarring is possible with any second-degree burn. Deeper burns scar more. Keep the healing skin moisturized with fragrance-free lotion once the wound has closed. Protect the area from sun exposure for at least a year — healing skin burns easily and scars more noticeably.
What Not To Do When Treating a Second-Degree Burn
Several common practices make burns worse. Popping blisters tops the list. An intact blister is a natural sterile dressing. Once popped, the wound is exposed to bacteria.
Do not use ice or ice water for more than a few minutes. Ice causes blood vessels to constrict, which reduces blood flow to the area and can increase tissue damage. Cold water is fine; ice is not.
Avoid cotton balls or fluffy bandages directly on the wound. Fibers stick to the burn and pull off new skin when removed. Use sterile non-stick pads instead.
Do not apply alcohol, hydrogen peroxide, or iodine to a second-degree burn. These products damage new tissue cells and slow healing. Plain soap and water is enough for cleaning.
Do not ignore signs of infection. Redness spreading beyond the burn edge, increasing pain, pus, or fever all require medical attention. An infected burn can progress to a serious condition affecting the whole body.
How To Care for a Second-Degree Burn as It Heals
Daily care keeps the burn clean and supports healing. Wash your hands before touching the burn. Gently clean the area with mild soap and lukewarm water. Rinse well and pat dry.
Apply a fresh layer of antibiotic ointment or petroleum jelly. This keeps the wound moist, which speeds healing. A moist wound heals faster than a dry one. Cover with a fresh non-stick dressing.
Watch for signs the burn is healing. New pink tissue appearing around the edges is a good sign. The wound should gradually shrink. If it does not, or if the area looks worse after a week, see a doctor.
Keep the burn elevated if it is on an arm or leg. Elevation reduces swelling. Swelling slows blood flow and delays healing.
Eat normally and stay hydrated. Healing burns require extra energy and protein. Most people heal fine with a regular diet. There is no evidence that supplements speed burn healing.
When a Second-Degree Burn Becomes a Medical Emergency
Some situations require immediate emergency care. These are not optional. Call emergency services or go to an emergency room if any of these apply:
- The burn covers a large area or is deep
- The burn is on the face, hands, feet, or genitals
- Breathing is difficult or the person inhaled smoke
- The burn came from electricity, chemicals, or an explosion
- The person is confused, dizzy, or losing consciousness
- Signs of infection appear — spreading redness, pus, fever, or worsening pain
Large burns can cause dehydration because damaged skin loses fluid. This can lead to shock. Emergency care includes IV fluids and specialized burn treatment.
Chemical burns need different first aid. Brush off dry chemicals first, then flush with water for at least 20 minutes. Do not use water on some chemicals, like certain metals, that react with it. Call poison control for specific guidance.
Electrical burns may look small on the surface but can damage tissue deep inside. These always need medical evaluation.
Frequently Asked Questions
Can I put butter or oil on a second-degree burn?
No. Butter, oil, and toothpaste trap heat and increase infection risk. Use cool running water and a sterile dressing instead.
Should I pop the blisters on a second-degree burn?
No. Leave blisters intact. They protect the raw skin underneath and reduce the chance of infection.
Is it okay to use ice on a second-degree burn?
No. Ice can damage skin tissue and cause frostbite. Use cool running water for 10 to 15 minutes.
How do I know if my second-degree burn is infected?
See a doctor if you notice spreading redness, increased pain, pus, or fever. These are signs of infection that need treatment.
Treating a second-degree burn at home is possible for small burns. Cool the area, protect it with a clean dressing, and watch for infection. Larger burns, burns in sensitive areas, and burns in people with health conditions need medical care. When in doubt, have a doctor look at it.
