Most minor burns heal fully within two to three weeks when you cool the skin quickly, keep the wound clean, and protect it from infection. The single most important step you can take right away is running cool water over the burn for at least 20 minutes. Everything after that, from choosing the right dressing to watching for infection, builds on that foundation.
How you care for a burn depends on how deep it goes. Here’s what to know about treating burned skin at each stage of recovery.
Identify How Deep Your Burn Goes
Burns fall into three categories based on how many layers of skin are damaged, and each heals differently.
- First-degree burns damage only the outermost layer of skin. They look dry and red, similar to a sunburn, and they hurt. These typically heal on their own within a week.
- Second-degree burns reach into the deeper layer of skin (the dermis). They’re moist, red, and extremely painful, and they usually blister. Shallow second-degree burns heal in two to three weeks. Deeper ones take longer and often leave scars.
- Third-degree burns destroy the full thickness of skin down into the fat layer. The burned area may appear white, black, brown, or red, and it feels dry rather than moist. Ironically, these burns are less painful because the nerve endings are destroyed. Third-degree burns cannot heal on their own from the center of the wound and always need professional treatment.
If your burn blisters, covers a large area, wraps around a finger or limb, or is on your face, hands, feet, or genitals, get medical care. Any burn that looks white, brown, or black needs emergency attention. For small, superficial burns that stay red and painful, home treatment is usually enough.
Cool the Burn Immediately
As soon as you’re burned, get the area under cool, running water for at least 20 minutes. This isn’t a suggestion you can shorten to a quick rinse. Twenty minutes is the minimum recommended by burn care guidelines, and cooling can continue to help for up to three hours after the injury. The water should be cool, not cold. Room-temperature tap water works well.
Do not use ice, ice water, or anything frozen. Ice restricts blood flow to damaged tissue, which slows healing and can cause additional injury. If the burn is deep, you may not be able to feel when the area becomes dangerously cold, raising your risk of frostnip or even frostbite on top of the burn. Ice can also increase your risk of infection by further damaging tissue. Butter, toothpaste, and other home remedies are equally harmful because they trap heat in the skin and introduce bacteria.
After cooling, gently pat the area dry. Remove any clothing or jewelry near the burn before swelling starts, but don’t pull off anything stuck to the wound.
Keep the Wound Clean and Covered
Once the burn is cooled, apply a thin layer of antibiotic ointment and cover it with a non-stick dressing. Antimicrobial ointments are the most commonly used topical treatment for small to moderate burns at major burn centers in the U.S. and Europe. They’re easy to apply and remove during cleaning, and they work well on sensitive areas like the face and ears.
Change the dressing daily, or whenever it gets wet or dirty. Each time you change it, gently wash the burn with mild soap and water, pat it dry, reapply ointment, and cover with a fresh non-stick bandage. Don’t pop blisters. They act as a natural sterile barrier while new skin forms underneath. If a blister breaks on its own, clean the area gently and re-dress it.
Manage Pain During Recovery
Burns hurt, especially second-degree ones. Over-the-counter pain relievers like ibuprofen, acetaminophen, or naproxen all work for burn pain. Ibuprofen and naproxen also reduce inflammation, which can help with swelling. Follow the dosing instructions on the package. Don’t give aspirin to anyone under 18.
Cool compresses (not ice) can also ease discomfort between pain medication doses. If over-the-counter options aren’t controlling your pain, that’s a signal the burn may be more serious than it looks.
How Burn Skin Heals in Stages
Your body repairs burned skin through three overlapping phases. Understanding these helps you know what’s normal and what’s not.
The first phase is inflammation, lasting from the moment of injury through roughly day four. The area swells, turns red, and feels warm. This is your immune system flooding the site with cells that clear out damaged tissue and fight off bacteria. It looks alarming but it’s a necessary step.
Next comes the proliferative phase, from around day four through weeks two to six. Your body starts building new tissue. Skin cells migrate across the wound surface while deeper cells produce collagen to fill in the gap. You may notice the wound shrinking and new pink skin forming at the edges. This is the most active repair period, and keeping the wound moist and protected matters most during these weeks.
The final phase is remodeling, which can last up to 18 months after the wound closes. During this time, the collagen laid down in the previous phase matures and strengthens. Scars gradually soften, flatten, and fade. The skin may feel tight or itchy as it reorganizes. This is normal and slowly improves.
Watch for Signs of Infection
Infection is the biggest risk during burn healing, and catching it early makes a significant difference. Check your burn daily when changing dressings. Normal healing produces a small amount of clear or slightly yellow fluid. That’s not a concern.
What should concern you is thick, milky, or foul-smelling drainage. Pus from an infected burn can appear white, yellow, green, pink, or brown, and it usually smells bad. Other warning signs include increasing redness spreading outward from the burn, the skin around the wound feeling hotter than the surrounding area, worsening pain after the first few days (when it should be improving), or a fever. If the color or smell of drainage changes, the infection is likely getting worse and needs medical attention promptly.
Eat Enough Protein to Support Repair
Your body needs extra protein to rebuild burned skin. The collagen and new skin cells your body produces during healing are made from protein, and a burn increases your protein requirements well above normal levels. European clinical nutrition guidelines recommend burn patients consume roughly double the normal daily protein intake.
In practical terms, this means eating protein at every meal: eggs, chicken, fish, beans, Greek yogurt, or protein shakes if your appetite is low. Vitamin C also plays a direct role in collagen production, so including fruits and vegetables helps. Staying well-hydrated supports every phase of wound healing. If you have a larger or deeper burn, ask your care team about specific nutritional targets.
Minimize Scarring After the Wound Closes
Once the burn wound has fully closed (no open or weeping areas), you can start scar prevention. Silicone scar sheets are the best-studied option. They work by keeping the scar hydrated, applying gentle pressure, and limiting excessive collagen buildup. Consistent use can reduce the redness, thickness, hardness, and itchiness of raised scars.
For best results, wear silicone sheets 12 to 24 hours a day, replacing them as directed. This process takes weeks to months, so consistency matters more than any single application. Never apply silicone sheets to open, broken, or infected wounds.
Protect healing and newly scarred skin from the sun. New skin is extremely vulnerable to UV damage, which can darken scars permanently. Use a high-SPF sunscreen or keep the area covered for at least a year after the burn. Gentle massage of the scar once it’s fully closed can also help break up collagen fibers and improve flexibility over time.
