Cool running water is the single best first response for a burn, and it works best when applied within three hours of the injury. After cooling, what you put on the burn depends on its severity, but most minor burns heal well with a simple moisture barrier like petroleum jelly or aloe vera and a non-stick bandage. Here’s a step-by-step guide to treating burned skin at home and knowing when you need professional care.
Cool Running Water First
Before you put anything on a burn, hold it under cool (not cold) running water for a full 20 minutes. This isn’t just about pain relief. Twenty minutes of cool water reduces cell damage, improves wound healing, and decreases scar formation. The key details: the water should be cool, not icy, and you have a three-hour window from the time of injury for this to be effective. Even if you can’t start immediately, cooling within that window still helps.
Ice, ice water, and very cold water can actually make the injury worse by constricting blood vessels and deepening tissue damage. Stick with comfortable, cool tap water.
Know Your Burn’s Severity
What you should put on the burn depends on how deep it goes.
- First-degree burns affect only the outermost layer of skin. They look red (or show color changes on darker skin) and hurt, similar to a sunburn. These are fully treatable at home.
- Second-degree burns go deeper into the second layer of skin. They cause swelling, blistering, and intense pain. The skin may look red, white, or splotchy. Shallow second-degree burns can be managed at home, but deeper ones can scar and may need medical attention.
- Third-degree burns destroy all layers of skin and sometimes the fat and muscle beneath. The skin may look black, brown, white, or leathery. Because nerves are destroyed, these burns can be surprisingly painless. They always require emergency medical care.
The advice below applies to first-degree burns and minor second-degree burns smaller than about three inches across.
Best Topicals for Minor Burns
Once you’ve cooled the burn for 20 minutes and gently patted it dry, you want to keep the area moist. Dry, exposed burns heal more slowly and scar more easily. You have several good options.
Petroleum jelly is one of the simplest and most effective choices. It protects the damaged area, locks in moisture, doesn’t irritate or sensitize the skin, and won’t stick to bandages. Apply a thin layer and cover with a non-stick bandage. Reapply when you change the dressing.
Aloe vera has genuine anti-inflammatory properties. Its active compounds reduce inflammation at the cellular level and have been shown in animal studies to shorten wound healing time. Pure aloe vera gel (not the bright green kind loaded with fragrances and alcohol) applied directly to a first-degree burn soothes pain and supports healing. You can reapply several times a day.
Medical-grade honey is a lesser-known option with solid clinical evidence behind it. A meta-analysis of randomized trials found that honey dressings were significantly better at clearing bacteria from burn wounds within the first week compared to standard clinical treatments. Patients using honey also reported earlier pain relief, with over a third being pain-free by day five compared to just 4% in the comparison group. If you try this, use medical-grade honey (sold in pharmacies), not regular grocery-store honey, and apply it under a sterile bandage.
Over-the-counter antibiotic ointments are sometimes recommended, but the evidence is mixed. Current guidelines note there’s no consensus on which topical agent is best for preventing infection in minor burns. For a clean, superficial burn, petroleum jelly alone performs well. If the burn has broken skin and you’re concerned about contamination, a thin layer of an antibiotic ointment is reasonable, but it isn’t strictly necessary for every minor burn.
What Not to Put on a Burn
Several home remedies that people reach for instinctively will make things worse. Butter, cooking oil, and toothpaste trap heat in the skin, cause irritation, and can deepen the injury. They also introduce bacteria directly into damaged tissue.
Ice and ice-cold water constrict blood flow to an area that desperately needs it for healing. Stick with cool water only. Egg whites, vinegar, and other folk remedies carry infection risk and have no evidence supporting their use.
Covering and Protecting the Burn
After applying your chosen topical, cover the burn with a non-stick bandage or gauze pad. Regular adhesive bandages can stick to the wound and tear healing skin when removed. Non-adherent pads (available at any pharmacy) sit over the wound without bonding to it. Secure the pad with medical tape on the surrounding healthy skin or wrap loosely with rolled gauze.
Change the dressing once or twice a day. Each time, gently clean the area with mild soap and water, pat dry, reapply your topical, and cover with a fresh bandage. If a blister forms, leave it intact. It acts as a natural sterile dressing. Popping it opens the door to infection.
Managing Pain
Burns hurt, and over-the-counter pain relievers help significantly. Ibuprofen reduces both pain and inflammation and can be taken at 400 mg every eight hours. Acetaminophen works well for pain alone at 1,000 mg every six hours, but don’t exceed 4,000 mg in a 24-hour period. Taking both together (they work through different mechanisms) provides stronger relief than either one alone for moderate burn pain.
Signs of Infection to Watch For
Most minor burns heal without complications in one to three weeks, but infection is the main risk to monitor. Watch for increasing redness spreading beyond the burn’s edges, warmth and tenderness in the surrounding skin, swelling that gets worse instead of better, or any pus or foul-smelling drainage. A burn that seemed to be healing but then gets deeper or more painful may be converting from a partial-thickness to a full-thickness injury, which is a sign of infection that needs medical evaluation.
Fever, rapid heart rate, and feeling generally unwell alongside a worsening burn wound suggest the infection may be spreading beyond the skin.
Long-Term Skin Protection
New skin that forms over a healed burn is highly vulnerable to sun damage. UV exposure on healing burn tissue can cause permanent pigment changes, leaving the area noticeably darker or lighter than the surrounding skin. Use a broad-spectrum sunscreen with SPF 30 or higher on the healed area whenever it’s exposed to sunlight, and keep this up for at least one year after the injury. Reapply frequently, especially after sweating or getting wet. Covering the area with clothing is even more reliable than sunscreen when possible.
