Boxcar Acne Scars Explained
Boxcar scars are a common type of acne scar that many people struggle with after dealing with severe acne. Understanding what they are and how they form can help you make informed decisions about treatment options.
What Are Boxcar Scars?
Boxcar scars are indented marks on the skin that look like small depressions or craters. They get their name because they resemble the shape of a boxcar on a train. These scars have sharp, well-defined edges and a broad base, which makes them stand out from other types of acne scars. The edges drop down into the skin like a small crater, and they can be either shallow or deep. Most boxcar scars appear on the cheeks and temple regions of the face, though they can also show up on the lower cheeks and jawline.
How Do Boxcar Scars Form?
Boxcar scars develop when severe inflammatory acne damages the skin’s deeper layers. When you have cystic acne or other intense inflammatory breakouts, the inflammation can destroy collagen in a specific area. Collagen is the protein that gives your skin its structure and support. When the body tries to heal the damaged area, it doesn’t always produce enough collagen to fill in the gap properly. This lack of underlying tissue support causes the skin to sink down, creating the characteristic depressed appearance of a boxcar scar.
The severity of the acne and how long the inflammation lasts both play a role in how deep the scar becomes. Additionally, picking or squeezing pimples can significantly increase the likelihood of scarring, making proper care essential to minimize long-term skin damage.
Why Some People Get Boxcar Scars More Than Others
Several factors influence whether someone will develop boxcar scars after acne. Genetics play an important role, as some people have a genetic predisposition to developing severe inflammatory acne and scarring. If your parents or siblings experienced severe acne and scarring, you may be more likely to have similar issues. Your skin type also matters, as different skin types respond differently to inflammation and healing.
The depth and severity of the acne inflammation, combined with how your body produces collagen during healing, determines whether you’ll end up with noticeable scars. Some people’s bodies produce too little collagen during the healing process, while others may produce too much, leading to different types of scars.
How Boxcar Scars Differ From Other Acne Scars
There are several types of acne scars, and boxcar scars have distinct characteristics that set them apart. Rolling scars, for example, are caused by fibrous bands beneath the skin that pull the surface downward, creating soft, wave-like depressions with gradual slopes. Ice pick scars are much deeper and narrower, resembling small puncture marks that penetrate deep into the skin. Hypertrophic scars are raised and firm, sitting above the skin surface rather than below it.
Boxcar scars fall into a category called atrophic scars, which means they involve a loss of tissue. What makes boxcar scars unique is their sharp, clearly defined edges and their broad, punched-out appearance. This distinguishes them from rolling scars, which have softer, more gradual slopes.
Treatment Options for Boxcar Scars
Treating boxcar scars is typically a multi-step process that requires precise diagnosis and commitment. Several treatment options are available, and the best choice depends on the depth and characteristics of your specific scars.
Subcision is one of the most common treatments for boxcar scars. This procedure involves using a special needle to break up the fibrous tissue beneath the scar, allowing the skin to rise and creating a smoother appearance. Subcision is often combined with fillers to provide additional volume and improve the scar’s appearance.
Laser resurfacing treatments, particularly fractional CO2 lasers, can be effective for boxcar scars. These lasers work by removing the outer layers of skin and stimulating collagen production in the deeper layers. This helps to fill in the depression and smooth out the scar.
Dermal fillers are another option that can temporarily improve the appearance of boxcar scars by adding volume beneath the scar, making it less noticeable. However, fillers are temporary and require repeated treatments to maintain results.
Microneedling with radiofrequency is another treatment approach that combines the benefits of microneedling with radiofrequency energy to stimulate collagen production and improve skin texture.
TCA Cross, which stands for chemical reconstruction of skin scars, uses trichloroacetic acid to treat atrophic acne scars. This treatment is often used for boxcar scars and can help improve their appearance over time.
Why Professional Treatment Matters
Because boxcar scars have distinct structural characteristics, they require different treatment approaches than other types of acne scars. A trained dermatologist can examine your skin closely and determine exactly what type of scars you have, ensuring that your treatment plan is tailored to your unique scar pattern and structure. Not all scars respond the same way to treatments, and what works for one type may be ineffective for another.
The key to successful treatment is accurate diagnosis followed by a comprehensive approach that may involve multiple treatments. Many people see the best results when combining different treatment methods rather than relying on a single approach.
Prevention and Moving Forward
While treating existing boxcar scars requires professional help, preventing new scars from forming is something you can control. Proper acne care, avoiding picking or squeezing pimples, and treating inflammatory acne promptly can all help minimize the risk of developing new scars. If you have a family history of severe acne scarring, being proactive about acne treatment becomes even more important.
If you’re concerned about boxcar scars on your face, consulting with a dermatologist is the best first step. They can assess your scars, discuss your treatment options, and create a plan tailored to your specific needs and goals.
