Burns and Scalds First Aid: What to Avoid and Common First-Aid Myths

Why “Home Remedies” (Butter, Oils, Toothpaste, Powders) Make Burns Worse

Many popular home treatments feel soothing at first, but they often trap heat, contaminate the wound, or make medical assessment harder. A fresh burn keeps releasing heat from deeper layers for a while; anything that forms a greasy or pasty layer can slow heat escape and prolong tissue damage.

Butter, cooking oils, petroleum jelly

• Trap heat: Greasy layers act like insulation, keeping heat in the skin.
• Increase infection risk: Food products are not sterile; they can carry bacteria and create a film that is hard to clean off later.
• Complicate dressings: Oily residue can prevent clean coverings from sitting properly and can interfere with clinician evaluation.

Toothpaste

• Irritating ingredients: Flavorings, detergents, and whitening agents can irritate damaged skin.
• False “cooling” sensation: Menthol-like effects can mask worsening pain without improving the injury.
• Hard to remove: Paste can lodge in broken skin or blisters, increasing contamination.

Powders (flour, cornstarch, talc, “burn powders”)

• Clumping and sticking: Powders can form a paste with wound fluid, sticking to tissue and making cleaning painful.
• Contamination: Kitchen powders are not sterile and can introduce debris.
• Obscures the burn: Makes it harder to see blistering, weeping, or color changes that guide next steps.

Plant-based or “natural” remedies (raw egg, honey from the pantry, herbal pastes)

• Not reliably sterile: Even products with antimicrobial properties in lab settings can be contaminated in real-world storage.
• Allergy/irritation risk: Damaged skin absorbs more; reactions can worsen swelling and pain.
• Delays appropriate care: People may keep reapplying instead of monitoring for worsening symptoms.

Ice and Overcooling: When “Colder” Becomes Harmful

Cooling is helpful, but ice and aggressive cooling can cause additional injury. Very cold temperatures can reduce blood flow to already-damaged tissue and may create a cold burn on top of the thermal burn.

What can go wrong with ice

• Frostbite-like damage: Direct ice contact can injure skin cells and small blood vessels.
• Worsened pain after numbness: Numbing can be followed by rebound pain and swelling.
• Overcooling in children and older adults: Prolonged cooling of large areas can contribute to chilling and stress on the body.

Practical “do not” checklist for cooling

• Do not apply ice cubes, ice packs, or frozen food directly to a burn.
• Do not use ice water baths for burned hands/feet.
• Do not keep cooling for so long that the person starts shivering or the skin becomes very pale or numb.

Antiseptics and Creams: When They’re Inappropriate for Fresh Burns

It is tempting to “disinfect” a burn immediately, but some antiseptics and creams can damage fragile tissue, cause chemical irritation, or trap heat if applied too early or too thickly. Fresh burns are not the same as dirty cuts: the priority is to avoid adding irritants and to keep the surface protected with minimal interference.

Common products that can be problematic

• Hydrogen peroxide: Can harm new, healing cells and delay recovery; bubbling does not mean “better cleaning.”
• Rubbing alcohol/spirits: Causes significant stinging, dries tissue, and can worsen irritation.
• Iodine solutions: Can irritate open or blistered skin; may stain and obscure assessment.
• Thick antibiotic ointment layers: Can be messy, trap heat if applied immediately after injury, and may trigger contact dermatitis in some people.
• Topical anesthetics (e.g., benzocaine/lidocaine creams): Can cause allergic reactions; on larger areas they may be unsafe, especially in children.
• “Burn gels” with multiple additives: Some are fine, but others contain fragrances or anesthetics that irritate; if you cannot verify ingredients, keep it simple.

Step-by-step: deciding whether to apply anything at all

1. Ask: Is the skin intact and only mildly red, or is there blistering/open skin?
2. If blistered/open: Avoid harsh antiseptics and avoid “scrubbing.” Prioritize gentle protection with a clean, non-adherent covering.
3. If mild and intact: If you use a product, choose something simple and non-irritating, and apply a thin layer only after the skin is no longer actively hot.
4. Stop immediately if burning/stinging increases, rash appears, or swelling worsens.

Blisters: Why Breaking Them Is Risky

Blisters are not “bad fluid that needs to come out.” A burn blister is a natural protective layer. Opening it turns a protected injury into an open wound, increasing pain and infection risk.

What goes wrong when blisters are popped

• Higher infection risk: The blister roof acts like a biological dressing; removing it exposes raw tissue.
• More pain and slower healing: Exposed nerve endings are more sensitive and prone to drying/cracking.
• Harder to dress: Open, weeping areas stick to gauze and can tear during changes.

Common “blister myths”

• Myth: “Letting the fluid out helps it heal.” Reality: The intact blister often heals more smoothly than a deliberately opened one.
• Myth: “It will burst anyway, so I should do it now.” Reality: If it bursts accidentally, you can protect it; intentionally opening adds contamination and trauma.

If a blister breaks on its own (practical steps)

1. Wash hands.
2. Rinse gently with clean water; do not peel away attached skin.
3. Cover with a clean, non-stick dressing; avoid fluffy cotton that sheds fibers.
4. Change the covering if it becomes wet/dirty, and monitor for increasing redness, warmth, swelling, pus, or worsening pain.

Chemical Burns: The Neutralization Misconception

A dangerous myth is that you should “neutralize” a chemical burn with an opposite chemical (acid vs. base). In real life, this can cause a heat-producing reaction, release harmful fumes, or spread the chemical over a larger area.

Why neutralizing is risky

• Exothermic reactions: Acid-base reactions can generate heat, adding a thermal burn to the chemical injury.
• Unknown concentration: Household and industrial products vary; you cannot reliably calculate safe neutralization.
• Splashes and spread: Mixing liquids can splash into eyes or onto unaffected skin.
• Gas release: Some combinations produce irritating or toxic vapors.

Examples of what to avoid

• Do not put vinegar on an alkali burn (e.g., from strong cleaners).
• Do not put baking soda on an acid burn.
• Do not mix cleaning agents “on the skin” to cancel them out.

Safe Alternatives: What to Do Instead (Quick Reference)

Use this list as a replacement for common myths. It aligns with the course’s earlier priorities: reduce ongoing damage, avoid contamination, and keep the injury easy to assess and protect.

Practical “myth-busting” scripts (what to say in the moment)

• “Put butter on it.” → “Grease can trap heat and make it worse. Let’s keep it clean and protected.”
• “Ice it.” → “Ice can damage the skin. We’ll cool it safely without freezing the tissue.”
• “Pop the blister.” → “The blister is a natural dressing. Opening it raises infection risk.”
• “Neutralize the chemical.” → “Mixing chemicals can create heat and fumes. We won’t do that.”
