What Is an Abrasion? A Simple Guide to This Common Skin Injury

Accidentally scraped your knee or brushed your skin against a rough surface? Chances are, you’ve experienced an abrasion—a very common but often misunderstood type of skin injury. While usually minor, an abrasion wound still needs proper care to prevent infection and help your skin heal smoothly.

In this easy-to-understand guide, we’ll break down everything you need to know about abrasive skin injuries, from what they are to how to treat them the right way.

What Is an Abrasion?

When the skin’s epidermis is scraped off by friction or rubbing against a rough surface, it results in an abrasion, a type of wound.  Unlike cuts or lacerations, abrasions usually don’t go very deep, but they can still sting, bleed a little, and become infected if not properly cleaned.

Common Causes of Skin Abrasions:

• Falling on pavement or gravel 
• Sports injuries (especially in cycling, football, or skateboarding) 
• Rubbing against hard or rough objects 
• Accidental brushes against walls or carpets (especially in children) 

Types of Abrasions

Not all skin abrasions are the same. Doctors usually classify them into these three types:

1. Superficial Abrasion

• Only affects the outermost layer of skin (epidermis) 
• Mild pain, redness, and possible light bleeding 
• Heals within a few days 

2. Deep Abrasion

• Goes deeper into the skin layers 
• Can cause more bleeding and scabbing 
• Takes longer to heal 

3. Road Rash (Traumatic Abrasion)

• Often caused by skidding on a rough surface like pavement 
• Can cover a large area of skin 
• May have dirt or debris embedded, requiring careful cleaning 

What Does an Abrasion Look Like?

A fresh abrasion wound may look like:

• Red or pink raw skin 
• Slight bleeding or oozing 
• A rough, scraped texture 
• In some cases, a thin scab forming after a day or two 

Example: Think of a “rug burn” or the scrape you get from falling off a bike—that’s a typical skin abrasion.

How to Treat an Abrasion at Home

The majority of small abrasive skin injuries are safe to treat at home.  Here’s a simple step-by-step guide:

1. Clean the Wound

• Gently rinse with clean water or saline. 
• Use mild soap to remove dirt. Avoid using hydrogen peroxide or alcohol—it can irritate the skin. 

2. Apply an Antibiotic Ointment

• Use an over-the-counter antibiotic cream (like Neosporin) to prevent infection and keep the wound moist. 

3. Cover with a Clean Bandage

• Use a sterile dressing or adhesive bandage to protect the wound from germs. 
• Change the dressing daily or if it gets dirty or wet. 

4. Watch for Signs of Infection

• Redness, swelling, pus, or increased pain may signal an infection. 
• If symptoms get worse, seek medical help. 

When to See a Doctor

You should visit a healthcare provider if:

• The abrasion is large, deep, or covers a sensitive area (like the face or joints) 
• There is dirt or gravel embedded that you can’t remove 
• Infection symptoms include fever, bad odor, and edema occur. 
• It has been five to ten years since you were last vaccinated against tetanus. 

Final Thoughts

While abrasions are usually minor injuries, they still need proper care to heal well. Whether it’s a scraped knee or a nasty road rash, knowing how to clean and protect a skin abrasion can help you avoid complications and discomfort.

Stay safe, wear the right gear when needed, and treat wounds quickly. Your skin will thank you!
