The single most important step for a burn is to cool it quickly with cool running water — this limits the damage. Never put toothpaste, butter, oil or ice on a burn.

Step-by-step

When to see a doctor urgently

Cool water first — home remedies harm. Cooling for 20 minutes genuinely reduces burn depth. Traditional remedies like toothpaste or butter trap heat and cause infection. This is not a substitute for medical care. In an emergency, call your local emergency number.

Frequently asked questions

How long should I cool a burn?

At least 20 minutes under cool running water, ideally within the first 3 hours of the burn. This limits the damage and eases pain.

Should I put toothpaste or butter on a burn?

No — never. They trap heat, raise infection risk and must be cleaned off later, causing more pain. Use only cool running water.

When does a burn need a doctor?

For burns larger than a coin, deep or white/charred burns, burns to the face, hands, feet, genitals or joints, chemical/electrical burns, or any burn in a child.
