What Does a Healed Bullet Wound Look Like?

A fully healed bullet wound on the skin typically appears as a round or oval scar, often slightly depressed or puckered, ranging from a few millimeters to several centimeters across depending on whether it was an entry wound, an exit wound, or a surgically repaired site. The scar tissue is usually paler or darker than the surrounding skin, sometimes with a shiny or waxy texture. But that surface-level description only captures part of the picture, because what a healed gunshot wound looks like depends heavily on where the bullet hit, what it passed through, how it was treated, and how the individual’s body heals.

Entry Scars Versus Exit Scars

When a bullet passes completely through the body, it leaves two wounds, and these heal into distinctly different scars. The entry wound is almost always smaller and neater. In fresh injuries, entry wounds are characterized by a round defect with an abrasion ring, which is the scraping of skin as the bullet pushes inward. Once healed, that entry scar tends to be a relatively compact, roughly circular mark. It may appear slightly indented because the tissue was punched inward.

Exit wounds are a different story. As a bullet exits, it is often tumbling, deformed, or fragmented, and it pushes tissue outward rather than compressing it inward. The resulting wound is frequently larger, more irregular, and more ragged. The healed exit scar reflects this: it tends to be bigger, with more uneven edges, and often has a more prominent or raised texture compared to the entry scar. If significant tissue was torn away on exit, the healed scar may sit in a visible depression where muscle or fat was lost.

Not every gunshot produces both. Bullets that lodge inside the body leave only an entry scar. And in some cases, the exit wound is barely larger than the entry wound, especially with high-velocity, non-deforming rounds that pass cleanly through soft tissue without hitting bone. Still, for most healed through-and-through wounds, you can distinguish the two: the smaller, rounder scar marks where the bullet went in, and the larger, more irregular one marks where it came out.

Why No Two Healed Bullet Wounds Look the Same

The appearance of a healed gunshot scar varies enormously from person to person. Several factors drive that variation, and understanding them explains why one person’s healed wound is a small pale dot while another’s is a wide, discolored, irregular patch.

Bullet type and velocity: A low-velocity handgun round that passes through soft tissue without fragmenting leaves a relatively clean wound channel. A high-velocity rifle round or a hollow-point bullet that expands on impact creates far more tissue destruction, leading to a larger, more complex scar.
Anatomical location: A wound through the fleshy part of the arm heals very differently from one that crosses the abdomen, the face, or a joint. Areas with more underlying muscle tend to fill in better. Wounds over bony prominences or through joints often heal with more noticeable deformity.
Bone involvement: When a bullet strikes bone, it can shatter into fragments and send bone splinters into surrounding tissue, creating a much wider zone of damage. Research on gunshot trauma to long bones has documented multiple fracture types including comminuted fractures (bone broken into several pieces) and butterfly fractures, as well as indirect fractures caused not by the bullet itself but by the shockwave it sends through nearby tissue.¹ A healed wound where bone was shattered will often show surface irregularity, a visible dent, or asymmetry in the affected limb.
Skin tone and genetics: People with darker skin tones are more prone to keloid and hypertrophic scarring, which means the healed wound may be raised and thickened rather than flat. Individual wound-healing biology varies widely regardless of ethnicity.
Medical treatment: A wound that was surgically cleaned, repaired, and closed heals differently from one that was left to close on its own. Skin grafts, flap repairs, and staged reconstructive surgeries all leave their own distinctive scar patterns layered on top of the original wound.

Because of all these variables, asking what a healed bullet wound looks like is a bit like asking what a healed car accident looks like. The range runs from a faint mark you might mistake for a minor burn to dramatic scarring and visible deformity.

Discoloration and Embedded Particles

One feature that often surprises people is the skin discoloration that can persist around a healed gunshot wound. This goes beyond the normal pale or pink color of scar tissue. At close range, gunpowder residue, soot, and tiny fragments of metal or other combustion products can be driven deep into the skin at the moment of injury. This creates what is sometimes called a traumatic tattoo: a permanent grayish, bluish, or dark speckling of the skin surrounding the entry wound.

Histological analysis of tissue with embedded combustible particles has shown that these fragments can sit in the deep layers of the skin and even in the fat layer beneath it.² Because the particles are physically lodged in tissue rather than staining the surface, they do not fade over time the way a bruise would. The discoloration is permanent unless treated. Removal techniques exist but can themselves leave some changes to skin pigmentation, including temporary lightening of the treated area with minimal additional scarring.²

Even without embedded particles, healed gunshot scars frequently show pigment changes. The scar itself may be noticeably lighter (hypopigmented) or darker (hyperpigmented) than the surrounding skin. These color differences tend to be more pronounced and more persistent in people with medium to dark skin tones. Over years, the contrast may soften somewhat, but it rarely disappears entirely.

How Surgery Reshapes the Final Scar

The surgical treatment a gunshot wound receives has an enormous influence on what the healed result looks like, sometimes more than the injury itself. A wound that is cleaned, debrided (meaning dead and damaged tissue is cut away), and closed promptly tends to heal into a tighter, more linear scar. In contrast, wounds left to heal by secondary intention, where the body fills in the gap with new tissue on its own, typically produce broader, more irregular scars.

For gunshot wounds to the face, where cosmetic and functional outcomes are especially important, the approach to debridement matters a great deal. Research on facial gunshot wound repair found that aggressive removal of non-viable tissue followed by immediate wound closure dramatically reduced infection and wound breakdown, dropping complications by roughly tenfold compared to more conservative approaches.³ About 15% of those patients went on to need additional plastic surgery procedures using local or distant tissue flaps to improve the final result.³

For wounds involving limb amputations from gunshot trauma, research has tracked the healing timeline closely. With appropriate surgical debridement techniques, complete resolution of inflammation and formation of a fully epithelialized connective tissue scar was observed by about day 12 after surgery.⁴ That is the basic healing timeline under controlled surgical conditions. In practice, many gunshot wounds take weeks or months to fully mature, and the scar continues to remodel for a year or more after closure.

Major reconstructive procedures can add their own visual signatures. Skin grafts look distinctly different from surrounding skin: they often have a slightly different texture, color, and thickness. Tissue flaps borrowed from another body region may be noticeably different in hair pattern, thickness, or skin tone. A person who has undergone extensive reconstruction of a gunshot wound may have a final result that looks less like a bullet wound scar and more like a patchwork of surgical scars.

Pathological Scarring

Not all gunshot wound scars settle into flat, stable tissue. Some develop pathological scarring, where the body overproduces collagen during repair and the scar grows beyond what is needed. The two main types are hypertrophic scars, which stay within the boundaries of the original wound but are raised and thickened, and keloids, which expand beyond the original wound margins and can continue growing over time. Both can be itchy, tight, or painful.

Gunshot wounds carry a higher risk of pathological scarring than clean surgical incisions because of the greater tissue destruction, contamination, and inflammation involved. Research on wound-healing interventions for gunshot injuries has found that treatments aimed at improving collagen metabolism can cut the incidence of pathological scarring roughly in half.⁵ That same research documented faster epithelialization, fewer complications, and shorter hospital stays in treated patients.⁵ But even with optimal treatment, some individuals are genetically predisposed to form keloids, and a gunshot wound gives that tendency a strong trigger.

Keloid scars from bullet wounds can be visually dramatic: firm, shiny, raised ridges or dome-shaped masses of scar tissue, sometimes much larger than the original wound. They are more common in younger people, in wounds on the chest, shoulders, or earlobes, and in people of African, Asian, or Hispanic descent. If you see a healed gunshot wound that looks much larger or more prominent than you would expect given the original injury, keloid formation is often the explanation.

Retained Bullet Fragments and What They Mean Years Later

Many gunshot wounds heal with pieces of the bullet still inside the body. When a bullet is not easily accessible or is in a location where surgical removal would cause more harm than leaving it in place, doctors typically leave it alone. In most cases, the body walls off the fragment in fibrous tissue, and the person carries it without obvious problems. You can sometimes feel a retained bullet as a hard lump under the skin, or it may show up incidentally on imaging done for an unrelated reason.

But retained fragments are not always inert. A systematic review of retained bullets and lead toxicity found that several factors increase the risk of developing lead poisoning over time, including where the fragment is located, whether it sits near a fracture site, the number of fragments, and how long the bullet has been in the body.⁶ Fragments lodged inside a joint space, where they are bathed in synovial fluid, appear to carry a substantially higher risk because the fluid dissolves lead from the bullet’s surface more readily.⁶

The timeline for these problems can be astonishingly long. One case report described a patient who developed severe anemia and critically elevated blood lead levels from a bullet retained in the knee joint, 27 years after the original gunshot wound.⁷ The diagnosis was initially missed because doctors were not thinking about a decades-old injury as a source of current symptoms. Lead poisoning from retained bullets can produce the same constellation of symptoms as lead exposure from any other source: fatigue, abdominal pain, anemia, cognitive difficulties, and in severe cases neurological damage. The key difference is that the exposure is continuous and ongoing as long as the fragment remains.

This means that for someone living with a retained bullet, the visible scar on the surface is not the whole story. The fragment inside may be quietly leaching lead, and any new unexplained symptoms years or decades later deserve evaluation with that history in mind.

Nerve Damage and Chronic Pain

A healed gunshot wound may look calm on the surface while causing significant ongoing pain underneath. Chronic pain is one of the most common long-term consequences of ballistic injuries, and the pain often has a neuropathic component, meaning it arises from nerve damage rather than ongoing tissue inflammation. Research on gunshot wound survivors has found that screening tools consistently point to neuropathic pain in these patients, and psychological distress including acute stress reactions is almost universal during the initial recovery period.⁸

Part of the reason for persistent pain is the formation of neuromas, which are tangled knots of nerve tissue that develop when a severed nerve tries to regrow but cannot reconnect properly. A study of patients with neuropathic pain in the ulnar nerve after gunshot wounds found neuromas in 40% of cases, and another 20% had shrapnel physically embedded within the nerve itself.⁹ A neuroma can cause burning, shooting, or electric-shock sensations in the area supplied by that nerve, sometimes triggered by light touch or pressure on the scar.

So when you look at a healed gunshot wound that appears to be nothing more than a small patch of scar tissue, the person living with it may experience that area very differently. They may feel constant burning or tingling. The scar area may be hypersensitive, meaning even clothing brushing against it is uncomfortable. Or they may have numbness in the skin around the scar if sensory nerves were destroyed rather than left partially intact. The visible scar and the felt experience of the wound are often wildly out of proportion.

Vascular Complications That Appear Later

Another category of hidden consequences involves blood vessels. When a bullet passes near or through a major artery or vein, it can create damage that does not become apparent until months or years after the wound has healed on the surface. One of the more serious delayed complications is an arteriovenous fistula, an abnormal connection between an artery and a vein that forms at the site of vascular injury. These fistulas can gradually enlarge over time, potentially causing swelling, pain, and strain on the heart as blood is shunted through the abnormal pathway.

Case reports have documented arteriovenous fistulas developing after gunshot wounds in the pelvis, the legs, and the abdomen.¹⁰ A related problem is a pseudoaneurysm, where the wall of an artery is damaged and blood collects in a pocket outside the vessel, held in place only by surrounding tissue rather than a true vessel wall. Both conditions can present with a pulsating mass near the old wound site, unusual swelling, or a buzzing sensation that a doctor can hear with a stethoscope. The diagnosis of these vascular injuries is often delayed significantly because neither the patient nor their doctors connect new symptoms to an old healed wound.¹¹

Imaging plays a role here. CT scans can trace old bullet tracks through the body, revealing the path the projectile took and identifying retained fragments, vascular abnormalities, or organ damage that might not be obvious from the surface scar alone.¹² For someone with a healed gunshot wound who develops new or unusual symptoms near the old injury site, advanced imaging is often the tool that connects the dots.

When Old Scars Turn Dangerous

There is one rare but serious long-term risk that deserves mention because it is easy to miss: the development of cancer within a chronic scar. This is known as a Marjolin’s ulcer, and it most commonly takes the form of squamous cell carcinoma arising in old scar tissue from burns, chronic wounds, or traumatic injuries, including gunshot wounds.¹³ The latency period is typically long, often decades between the original injury and the appearance of cancer.

The mechanism is thought to involve chronic irritation and repeated cycles of breakdown and repair in unstable scar tissue, which can eventually push cells toward malignant transformation. The warning signs are a scar that had been stable for years suddenly developing a non-healing ulcer, new growth, or a change in texture or appearance. Marjolin’s ulcers tend to be aggressive and can metastasize, so any change in a long-standing gunshot scar, particularly ulceration or a nodule that does not resolve, warrants prompt medical evaluation. This is not a common outcome, but it is one that both patients and their doctors should keep in the back of their minds when an old war wound or gunshot scar starts behaving differently after years of stability.
