Burn Care: the first hours matter most
Correct first aid — cool running water for 20 minutes, no ice, no toothpaste or home remedies — genuinely changes outcomes in the first hour after a burn. Burn depth (superficial, partial, or full thickness) determines healing time and scarring risk, and burns covering a large area, the face, hands, joints, or genitals need specialist assessment regardless of apparent depth.
First aid: what to do in the first 20 minutes
Cool the burn under gently running cool (not ice-cold) water for about 20 minutes as soon as possible — this is genuinely the single most effective thing anyone can do in the first hour, reducing how deep the burn ultimately progresses. Remove any tight clothing or jewellery near the area before swelling starts, but do not attempt to peel off clothing that is stuck to the burn. Cover loosely with a clean, dry, non-fluffy cloth afterward. Never apply ice directly (it can worsen tissue damage), and never apply home remedies like toothpaste, butter, oil, or turmeric — all of these are unproven, can trap heat, and significantly increase infection risk.
Assessing burn depth
Superficial burns (like typical sunburn) affect only the outer skin layer — red, painful, no blistering, and heal within about a week without scarring. Partial-thickness burns involve deeper layers, blister, are very painful, and take 2-3 weeks to heal, sometimes with some pigment change. Full-thickness burns destroy the full skin depth, often appear white, brown, or leathery, and — counterintuitively — can be less painful than more superficial burns because nerve endings have been destroyed; these require specialist treatment and often grafting, and should never be assumed "minor" just because they don't hurt as much.
When a burn needs hospital-level care
Seek urgent medical care for: any burn larger than the affected person's own palm, burns on the face, hands, feet, joints, or genitals regardless of size, any burn that looks white, brown, or leathery, burns in young children or elderly patients, burns from chemicals or electricity, and any burn with signs of infection (increasing pain, spreading redness, pus, fever) during healing. When in doubt, especially with children, it's always safer to have a burn assessed than to wait and see.
Reducing scar risk from day one
How a burn is managed in its first days meaningfully affects final scarring — proper cooling, appropriate dressings that maintain a clean, moist healing environment, and avoiding infection all reduce scar severity. Once healed, sun protection on the new skin (which is more vulnerable to pigmentation) and, where a surgeon recommends it, silicone-based scar treatment and pressure garments for larger burns can further improve the eventual scar. See burn reconstruction for what's done if a scar restricts movement or needs later revision.
Frequently asked questions
Should I put ice on a burn?
No — ice can worsen tissue damage. Cool (not ice-cold) running water for about 20 minutes is the correct first step.
Should I apply toothpaste or oil to a burn?
No — these are common home remedies with no evidence of benefit and real risk of infection or trapped heat. Clean cool water, then appropriate dressing, is correct.
How do I know if a burn needs a doctor?
Any burn larger than the person's palm, on the face/hands/joints/genitals, that looks white or leathery, or in a child or elderly person, should be assessed urgently — even if it doesn't look painful, since full-thickness burns can be less painful due to nerve damage.
