Alcohol Or Hydrogen Peroxide: Which Heals Cuts Better?

When it comes to treating cuts and scrapes, it's important to know which products to use to effectively clean and heal the wound. While hydrogen peroxide and rubbing alcohol are commonly used to disinfect household surfaces, they are no longer recommended for use on wounds as they can damage healthy tissue, delay healing, and irritate the wound. So, what should you use to clean your cuts and scrapes?

Should I put alcohol or hydrogen peroxide on a cut?

Hydrogen peroxide and alcohol can damage healthy tissue

Although hydrogen peroxide and alcohol can be used to clean wounds, they are no longer recommended for this purpose. This is because they can damage healthy skin cells and immune cells, slowing down the healing process.

Both substances are extremely harsh on the skin. Hydrogen peroxide, for example, contains an extra oxygen molecule, which causes oxidation and destroys cell walls. This means it doesn't just kill bacteria, but also attacks healthy tissue, including skin and immune cells. It also slows blood vessel formation, which is crucial for wound healing.

Similarly, rubbing alcohol can damage the skin, especially at high concentrations. It also kills cells indiscriminately, preventing wounds from healing.

Instead of using hydrogen peroxide or alcohol, experts recommend cleaning wounds with mild soap and water. This is a much gentler way to remove dirt, debris, and bacteria from wounds without causing further damage or irritation.

If you have a more serious wound that is large, deep, or bleeding nonstop, you should seek professional medical treatment.

The best way to clean a cut is with soap and water

While cleaning a wound with hydrogen peroxide or alcohol may remove debris and bacteria, these substances can harm healthy tissue, delay healing, and kill cells indiscriminately. Instead, experts advise cleaning cuts and scrapes with mild soap and water. This method effectively removes dirt, debris, and bacteria from the wound, reducing the risk of infection.

To clean a cut or scrape, start by assessing the seriousness of the wound. If it is a deep wound or is bleeding nonstop, seek professional medical attention. If it is a minor wound, you can treat it at home.

First, wash your hands thoroughly to minimize the risk of bacteria transferring to the wound and causing an infection. Then, use a clean and sterile cloth or gauze to gently apply pressure around the wound until the bleeding stops. If there is any debris in the wound, such as small pebbles or splinters, remove it gently with clean tweezers.

Next, irrigate the wound by gently rinsing it with clear, warm, running water for at least five minutes. Use a washcloth, mild soap, and warm water to clean around the wound. Finally, apply a thin layer of Vaseline or petroleum jelly to the wound and cover it with a bandage to keep it moist and protect it from dirt and bacteria.

Alcohol works faster at killing germs but can damage surfaces

While both alcohol and hydrogen peroxide can be used to clean wounds, experts now advise against it. This is because both substances can damage healthy tissue, slowing down the healing process.

Rubbing alcohol, or isopropyl, is a faster-acting disinfectant compared to hydrogen peroxide. It can be used on many surfaces, but it may damage porous materials such as wood or granite and strip protective coatings from others. It is also harsh on the skin, especially at high concentrations.

Hydrogen peroxide is a powerful disinfectant due to its extra oxygen molecule, which causes oxidation and breaks down substances into less harmful components. It is suitable for use on many household surfaces, including wooden cutting boards, but it should be rinsed off after application. It also has a bleaching effect, so it should be used with caution on fabrics.

For these reasons, it is recommended to clean wounds with mild soap and water, as this is a gentler method that does not irritate the wound or impede the healing process.

Hydrogen peroxide is more effective against certain bacteria

While it is no longer advised to use hydrogen peroxide on wounds, it is still a commonly used antiseptic that is effective against bacteria, viruses, and protozoa. Hydrogen peroxide is a pro-radical that acts as a stable hydroxyl radical distributor. The extra oxygen molecule in hydrogen peroxide causes oxidation, which destroys cell walls and causes substances to break down into less harmful components.

In addition, hydrogen peroxide has been shown to have antifungal activity against many microorganisms. For instance, it has been demonstrated to be effective against P. expansum and Candida albicans and Streptococcus mutans.

However, it is important to note that hydrogen peroxide can be detrimental to wound healing. Its reactive power is not specific to germs, and it also kills normal cells within the wound, including healthy skin cells and immune cells, and slows blood vessel formation, all of which are important for wound healing.

Cuts heal faster when kept moist and covered

While small cuts and scrapes can be left uncovered, moisture is usually needed to help speed up the healing process. Air dries out the wound and promotes cell death, while a moist environment encourages faster replication of epithelial cells and faster wound healing.

It is important to keep wounds moist by dabbing them with petroleum jelly or Vaseline when changing the bandage each day. A dry bandage will keep dirt and bacteria away, and petroleum jelly will help keep the wound moist. Leaving a wound uncovered can slow down the healing process and makes the wound more likely to be painful.

Cuts and scrapes should be cleaned with mild soap and water. While hydrogen peroxide or rubbing alcohol can be used to initially rinse away debris and bacteria, they should not be used after the first cleaning as they can slow down wound healing by killing healthy cells.

Covering the wound with a sterile bandage promotes faster healing, keeps out bacteria and other contaminants, and reduces pain. It is recommended to change the bandage daily or more often if the cut reopens or begins bleeding again.
