What Should You NOT Put on a Cut?

Common First Aid Mistakes to Avoid

You've heard it before: not everything in your medicine cabinet belongs on a cut. Some of the most commonly used household remedies can actually work against your skin's appearance during first aid recovery.

When a minor cut or scrape happens, the instinct is to reach for whatever is nearby. But the wrong product, or the wrong approach, can irritate skin, leave it looking worse, or simply fail to protect against the kind of microbial exposure that matters in those first minutes after an injury.

Below, we break down the most common first aid mistakes and explain what the better alternatives actually look like.

1. Hydrogen Peroxide

Why people use it: The bubbling action feels like it's working — and for a long time, hydrogen peroxide was a household staple for wound care.

The problem: Hydrogen peroxide is a strong oxidizing agent. While it does kill some bacteria on contact, it is broadly disruptive to skin cells and is generally considered too harsh for direct wound application by most dermatologists and first aid guidelines today.

Better option: A first aid antiseptic product formulated with an FDA monograph-approved ingredient like benzalkonium chloride, such as NOxyDERM™ antiseptic foam, helps protect against infection in minor cuts, scrapes, and burns without the harsh oxidizing effect. Read More

2. Rubbing Alcohol (Isopropyl Alcohol)

Why people use it: It's widely available, fast-drying, and associated with sanitization — which feels appropriate for a wound.

The problem: Alcohol is known to be extremely drying and irritating when applied directly to broken skin. It can cause a burning sensation and may affect the skin's surface appearance during recovery. Like hydrogen peroxide, it has largely been replaced by gentler antiseptic options in current first aid best practices.

Better option: Save the rubbing alcohol for sanitizing tools and surfaces. For minor skin wounds, use a purpose-formulated first aid antiseptic foam or spray.

3. Iodine or Betadine in Concentrated Forms

Why people use it: Iodine has a long history in wound care and the brown staining is often perceived as evidence that it's working.

The problem: Full-strength iodine solutions can be harsh on skin and may cause staining and irritation. The discoloration can also make it harder to monitor the appearance of the wound area over time. Current first aid guidance generally favors gentler, skin-compatible antiseptic options.

Better option: A non-staining, non-irritating antiseptic foam formulated for everyday first aid use provides protection support without the side effects that make monitoring more difficult.

4. Toothpaste, Butter, or Home Remedy Pastes

Why people use it: Home remedies are often passed down through families. Toothpaste is said to "cool" burns; butter is applied to minor scalds in many households.

The problem: These products were not formulated for use on broken skin and introduce unnecessary substances into an already disrupted area. They can affect skin appearance and are not substitutes for first aid antiseptics.

Better option: For minor burns, cool the area with running water (not ice), then apply a first aid antiseptic designed for burns. Keep a proper first aid kit stocked so you always have the right product on hand. Read More 

5. Nothing at All (Skipping Antiseptic Protection)

Why people skip it: The cut looks small, it will "take care of itself," or the antiseptic is not within easy reach.

The problem: All breaks in the skin, even minor ones, introduce the possibility of microbial exposure from everyday surfaces. Skipping antiseptic protection after a minor wound means foregoing a simple, recommended step in proper first aid..

Better option: Keep a first aid antiseptic product readily accessible at home, in your car, and in travel and sports bags. NOxyDERM™ antiseptic foam is ideal for home, travel, sports, and first aid kits, designed for everyday injuries and easy to apply with one hand.

What You SHOULD Use on a Minor Cut

The simple, effective first aid routine:

  • Rinse the wound gently with clean water

  • Apply a first aid antiseptic with an FDA monograph-approved ingredient (like benzalkonium chloride) to help protect against infection

  • Cover with an appropriate bandage

  • Keep it clean and dry; change the bandage daily or when it gets wet

NOxyDERM™ is a first aid antiseptic foam for minor cuts, scrapes, and burns. It contains benzalkonium chloride to help protect against infection, and nitric oxide to support healthier-looking skin during routine first aid, making it a thoughtful choice for everyday first aid kits.

When to See a Doctor

First aid antiseptics are for minor cuts, scrapes, and burns only. Seek professional medical care if:

  • The wound is deep, gaping, or won't stop bleeding with gentle pressure

  • You see significant spreading redness, warmth, swelling, or discharge beyond the initial wound area

  • You develop a fever

  • The wound involves an animal bite, puncture from a rusty object, or any other situation your instinct says warrants professional attention
