Punch elevation works by physically lifting the depressed floor of a boxcar scar flush with the surrounding skin surface, which instantly eliminates the visual depression that creates the characteristic shadowed appearance of the scar. When a dermatologist uses a 1.5–3.5 mm disposable punch tool to elevate the scar tissue, they’re removing the depth differential that makes the scar visible—essentially raising the sunken area so it matches the level of healthy skin around it. This is why punch elevation is considered such an effective and straightforward approach to treating deep boxcar scars.
For someone with a boxcar scar on their chin or cheek, punch elevation can make a visible difference in a single procedure, which is why dermatology practices across the U.S. recognize it as a standard treatment option. This article covers how the technique actually works, the clinical evidence supporting it, when it’s most effective, and how it compares to other scar treatments.

What Makes Boxcar Scars Different and Why They Respond to Punch Elevation
Boxcar scars are defined by their distinctive shape—flat-bottomed, sharp-edged depressions that look like small pox marks or the indentations left by a hole punch on paper. Unlike rolling scars (which have rounded slopes) or icepick scars (which are narrow and deep), boxcar scars have a clearly defined floor that sits well below the skin surface. The visual problem isn’t the scarred tissue itself—it’s the depression. Light hits that depression and creates a shadow, which is what makes the scar noticeable. Punch elevation targets this exact problem.
By lifting the scar floor upward to match the surrounding skin level, the depression disappears, and so does the shadow. The technique works on the principle that depth is the enemy of appearance—flatten the depth, and you flatten the visibility. This is why punch elevation is classified in dermatological literature as efficacious, economical, and relatively safe for treating deep boxcar and icepick scars. However, the technique is most effective for wider and deeper scars, not shallow or narrow indentations. If your boxcar scar is particularly deep or wide, punch elevation becomes an especially attractive option.
How the Punch Elevation Procedure Physically Lifts Scar Tissue
The procedure itself is straightforward. A dermatologist uses a disposable punch tool that comes in sizes from 1.5 mm to 3.5 mm—roughly the diameter of the scar or slightly larger. The punch is essentially a cylindrical blade that the surgeon places over the scar and gently rotates to cut around the perimeter of the scarred tissue. This isolates the depressed scar tissue so it can be elevated.
Once the scar is isolated by the punch, the tissue is then elevated upward until its surface sits flush with the surrounding skin. The elevation is held in place through closure with either Steri-Strips (surgical tape) or sutures, depending on the depth and size of the scar. The goal is simple but effective: raise the floor of the depression until there’s no longer a noticeable depth difference. However, one important limitation is that punch elevation works best on isolated, well-defined scars. If scarring is diffuse or spread across a large area, the technique may need to be combined with other approaches to address the entire region effectively.
What the Clinical Evidence Says About Punch Elevation
Punch elevation isn’t a new technique, and it isn’t experimental—it’s backed by peer-reviewed research in dermatology journals. Evidence-based surgical management guidelines for post-acne scarring have been published in journals like *Skin Research and Technology*, confirming punch elevation as a recognized and effective treatment modality. multiple dermatology centers have documented its success, and the procedure is now a standard offering at dermatology practices across the U.S.
The most exciting recent evidence involves combining punch elevation with other treatments. A 2024 clinical study published in the *Dermato Journal* examined punch elevation paired with Dermapen (a micro-needling device) and found enhanced results compared to either technique alone. The combination approach appears to address scarring at multiple levels—punch elevation handles the structural depression while Dermapen stimulates collagen remodeling in the surrounding tissue, leading to more comprehensive improvement. This combination therapy represents current best practice for patients with moderate to deep boxcar scarring.
When Punch Elevation Is the Right Choice for Your Scars
Punch elevation is most effective for boxcar scars that are either wider or deeper than average. A single scar that’s 2–3 mm across and clearly defined is an ideal candidate. If you have three or four well-separated boxcar scars on your face, punch elevation can address each one individually in a single procedure. However, if your scarring consists of many shallow indentations spread across a large area, punch elevation may not be the most efficient approach—you might benefit more from a resurfacing treatment like laser therapy or chemical peels.
Another consideration is the scar floor itself. Punch elevation works best when the scar floor is relatively smooth and firm, allowing for clean elevation and closure. If the scar tissue is soft or irregular, or if there’s significant fibrosis (thickened scar tissue), your dermatologist may recommend combining punch elevation with other techniques or trying a different approach first. A consultation with a board-certified dermatologist is essential to determine whether punch elevation is appropriate for your specific scarring pattern and skin type.
Realistic Expectations and Recovery Considerations
After punch elevation, the scar area will have some redness and mild swelling for a few days, similar to any minor surgical procedure. The Steri-Strips or sutures will remain in place for about a week, after which they’re removed and the tissue begins to heal. Most people can return to normal activities within a few days, though strenuous exercise should be avoided for about a week.
One important warning: punch elevation works on depth, not on color. If your boxcar scar is still red or purple (indicating active inflammation), punch elevation alone won’t eliminate that discoloration—you’ll need to address the redness separately with treatments like laser therapy or intense pulsed light (IPL). Additionally, punch elevation is not a solution for atrophic or keloid scars, which require different approaches. Make sure your dermatologist has evaluated whether your scar is truly a boxcar scar and whether it’s appropriate for this specific technique before proceeding.
The Combined Approach: Punch Elevation with Dermapen
When dermatologists pair punch elevation with Dermapen micro-needling, they’re creating a comprehensive scar treatment strategy. Punch elevation immediately addresses the structural depression by lifting the scar floor, while Dermapen stimulates the production of new collagen in the surrounding tissue over the following weeks and months.
This two-pronged approach appears to produce more dramatic and longer-lasting improvements than either technique alone. The timing of this combination varies by dermatologist—some perform both procedures on the same day, while others space them out to allow for initial healing from the punch elevation before adding micro-needling. According to the 2024 *Dermato Journal* study, the combination approach showed statistically significant improvements in scar appearance that persisted at follow-up visits, making it an evidence-supported option for anyone with moderate to deep boxcar scars who wants the best possible outcome.
Where Punch Elevation Fits in the Modern Treatment Landscape
Punch elevation has become more popular in recent years as dermatologists have moved away from relying solely on laser treatments and chemical peels for scar management. These resurfacing treatments can help with shallow scars and color issues, but they don’t address the mechanical depth of a true boxcar scar the way punch elevation does. That’s why dermatology centers now recognize punch elevation as a foundational technique—often the first choice for well-defined, depressed scarring.
As scar treatment continues to evolve, the trend is toward combination therapy rather than single-modality approaches. Punch elevation often serves as the structural foundation, whether combined with Dermapen, laser therapy for residual redness, or chemical peels for skin texture. This layered approach reflects an understanding that boxcar scars have multiple components (depth, redness, texture), and addressing all of them produces better cosmetic results. If you have boxcar scars, asking your dermatologist specifically about punch elevation should be part of any comprehensive treatment consultation.
Conclusion
Punch elevation lifts boxcar scars because it directly addresses the source of their visibility—the depression. By physically elevating the scar floor flush with surrounding skin, the procedure eliminates the depth differential that creates shadow and makes the scar noticeable. The technique is backed by clinical evidence, recognized as a standard treatment option at dermatology practices, and can be used alone or combined with other treatments like Dermapen for enhanced results.
It’s particularly effective for wider and deeper boxcar scars that are clearly defined and isolated. If you’re considering treatment for boxcar scars, punch elevation deserves serious discussion with a board-certified dermatologist. The procedure is economical, relatively safe, and offers straightforward mechanics—no complex technology required, just direct mechanical correction of the structural problem. A dermatologist can evaluate your specific scarring pattern and determine whether punch elevation is the right choice for you, or whether a combination approach would produce better results.
