A dermal piercing sits beneath the skin through a single entry point, while a surface piercing passes through a fold of skin with both an entry and an exit hole. That single structural difference drives nearly everything else people care about when choosing between the two: where you can place them, how long they last, how they heal, and how they come out. Both types carry higher rejection rates than traditional piercings through cartilage or earlobes, but for different mechanical reasons that are worth understanding before you commit.
How a Surface Piercing Works
A surface piercing uses a barbell that enters the skin at one point, travels under the surface for a short distance, and exits at a second point. Both ends of the jewelry sit flush against or slightly above the skin. The barbell used is typically a surface bar, which has a flat or staple-shaped design rather than a straight or curved post. That shape matters because it reduces the constant outward pressure that a curved barbell would exert on the tissue above it.
Because a surface piercing needs enough skin to form a pocket for the bar to travel through, placement is limited to areas where you can pinch up a fold of flat skin. Common locations include the nape of the neck, the chest between the collarbones, the hip bones, and the inner wrist. Areas with a lot of movement, bending, or friction from clothing are riskier because the bar shifts constantly, which accelerates rejection.
How a Dermal Piercing Works
A dermal piercing, sometimes called a microdermal or a dermal anchor, has no exit point. A small anchor plate with holes in it is inserted beneath the skin’s surface, and a single decorative top screws into a post that rises from the anchor. The holes in the plate allow tissue to grow through them over time, which is what holds the piercing in place. This is why dermal anchors have been described as a hybrid of implants and piercings: the anchor sits inside the tissue like an implant, while the visible jewelry sits on the surface like a piercing.1British Journal of Dermatology. Dermal piercings: unregulated high street surgery?
Insertion originally required a scalpel or dermal punch to create a small pocket in the skin, though the technique has evolved. Many piercers now use a standard piercing needle to create a smaller entry point, and anchors inserted this way are sometimes referred to as microdermal anchors.2British Journal of Dermatology. Dermal piercings: unregulated high street surgery? The procedure itself is quick, usually taking just a few seconds once the pocket is made. A dermal punch method removes a tiny circle of tissue, while the needle method displaces tissue rather than removing it. Both approaches leave a wound much smaller than what you would expect from hearing the word “surgery,” but the needle method tends to produce less initial trauma.
Placement Flexibility
The practical advantage of dermal piercings is that they open up areas of the body that surface piercings cannot reach. A surface piercing needs two viable puncture points close together on relatively flat, pinchable skin. A dermal needs only one point of entry. This means you can place a dermal anchor on the cheekbone, the center of the chest, the back of the hand, or near the collarbone, areas where there is not enough loose tissue to thread a bar through. Dermal anchors were originally developed in the United States around 2007 specifically to allow body decoration in spots where surface piercings would not heal well.3British Journal of Dermatology. Dermal piercings: unregulated high street surgery?
That said, placement flexibility does not mean every location is a good idea. High-movement areas like the fingers, the back of the hand, or anywhere a waistband frequently rubs will put stress on either type of piercing. For dermals, any location where clothing catches on the jewelry top increases the risk of the anchor being pulled or torn. Surface piercings fare poorly in the same zones for the same reason, plus the added problem that the bar beneath the skin is constantly being pushed and bent by body movement.
Rejection and Migration
Rejection is the concern that defines both of these piercing types, and it is where the structural difference between them has the most practical impact. When the body treats a piece of jewelry as a foreign object it wants to expel, the tissue slowly pushes it toward the surface. The piercing appears to migrate closer to the top of the skin over weeks or months, and eventually the jewelry sits so shallowly that it falls out or must be removed to avoid a worse scar.
Surface piercings are especially prone to this because the bar sits in a channel of tissue that is under constant low-grade tension. The body essentially treats the bar the way it would treat a splinter: something foreign trapped in the skin that it would prefer to push out. The flatter the area and the less movement it sees, the better the odds of the piercing surviving long term. But even under ideal conditions, many surface piercings eventually migrate. Some last years; others begin visibly moving within months.
Dermal piercings resist rejection through a different mechanism. Because the anchor plate has holes that allow tissue to grow through it, the piercing becomes partially integrated into the surrounding skin once healed. That tissue ingrowth creates a mechanical hold that a smooth-surfaced bar cannot achieve. As a result, dermals tend to be more resistant to slow migration. They are not immune to rejection, but the failure mode is different: a dermal is more likely to be pulled out by a snagging event or become irritated from repeated mechanical trauma than to slowly creep toward the surface on its own. When rejection does occur with a dermal, it usually follows chronic irritation or a poorly placed anchor rather than the body’s general intolerance of the foreign material.
Healing Timelines
Surface piercings typically take anywhere from three to nine months to heal fully, depending on placement and aftercare. The nape and chest tend to be on the longer end of that range, while areas with less movement may settle down sooner. During healing, the channel of tissue around the bar is fragile and susceptible to irritation from snagging, sleeping on it, or tight clothing.
Dermal piercings generally have a shorter initial healing window, often in the range of one to three months for the surface wound to close and the tissue to begin growing into the anchor. That shorter timeline partly reflects the smaller wound: a single puncture versus two. But “healed” for a dermal is a bit misleading. The skin above may look settled while the anchor is still integrating below. Full tissue ingrowth can take several additional months, and during that period the anchor is easier to dislodge than it will be once fully established. The practical takeaway is that dermals feel healed before they truly are, and this is when people get careless about protecting them from being caught on towels, seatbelts, or clothing.
Longevity and Lifespan
Neither type of piercing is considered permanent in the way a traditional lobe or cartilage piercing can be. Both are sometimes called semi-permanent, and the honest expectation is that most surface piercings and many dermal piercings will need to be retired at some point. Surface piercings are the less durable of the two on average: many begin migrating within the first year or two, and long-term retention beyond a few years is the exception rather than the rule. Some people keep surface piercings for much longer, but they tend to be in lower-stress placements with diligent care.
Dermal piercings have a better track record for longevity because the tissue integration gives them a physical anchor that surface bars lack. Five or more years is achievable with a well-placed dermal in a low-movement area. But they are still subject to gradual loosening over time, especially if the top gets bumped repeatedly. Once a dermal anchor begins to loosen, the jewelry starts sitting at an angle or becomes easy to wiggle, and at that point removal is the safer choice to avoid scarring from a slow partial rejection.
How Removal Differs
Removing a surface piercing is straightforward. The barbell is slid out through one of the two holes, much like removing any other barbell piercing. Once the jewelry is out, the entry and exit wounds close on their own, sometimes leaving minor scars where each puncture was.
Removing a dermal piercing is more involved because the anchor is designed to stay put. The tissue that has grown into and around the anchor plate must be separated before the anchor can be extracted. In emergency departments, a common approach has been to grip the base with hemostats and rock the anchor until it can be pulled through the skin, but this brute-force method can cause unnecessary damage, increase infection risk, and produce a worse scar.4Cureus. Step-by-Step Guide to the Punch Removal Technique for Dermal Piercing: A Surgical Pearl There is limited published guidance on best practices for dermal removal, which contributes to the problem. A punch removal technique has been described in the dermatologic literature as a way to extract the anchor and the scar tissue surrounding it in a cleaner, more controlled way, resulting in a more cosmetically appealing outcome.5Cureus. Step-by-Step Guide to the Punch Removal Technique for Dermal Piercing: A Surgical Pearl
Experienced piercers can also remove dermals, often by making a small incision alongside the anchor and loosening the tissue with a needle before sliding the plate out. But the important point for anyone considering a dermal piercing is that removal is a minor procedure, not simply pulling out a piece of jewelry. If the anchor has been in place for years and is well-integrated, the removal may require local anesthesia and a scalpel. You should factor in the exit plan, not just the installation.
Complications Shared by Both Types
Both surface and dermal piercings carry the same broad category of risks associated with any body piercing. Allergic contact dermatitis, often triggered by nickel content in lower-quality jewelry, is one of the more common issues. Bleeding, scarring, and keloid formation are possible with any puncture wound, and nerve damage is a concern in areas with superficial nerve branches.6PubMed. Body piercing: complications and prevention of health risks Infection is a risk during healing for both types, though the risk profile is slightly different: a surface piercing has two open wound sites during the healing period, while a dermal has one.
Scarring deserves special attention with these piercing types because rejection itself produces scarring. If you wait too long to remove a migrating surface piercing, the bar sits so close to the skin’s surface that the resulting scar is wider and more visible than it would have been if you had retired the piercing earlier. With dermals, scarring depends heavily on how the anchor is removed. The hemostat-and-rocking approach used in many emergency rooms tends to tear surrounding tissue, leaving a more obvious mark than a controlled removal performed by a dermatologist or experienced piercer.7Cureus.

Choosing the Right Jewelry Material
Material choice matters more for surface and dermal piercings than for traditional piercings because the jewelry is in prolonged contact with tissue that is more reactive than a fully healed fistula. Implant-grade titanium is the most widely recommended material for both types. It is lightweight, highly biocompatible, and does not contain nickel. Surgical steel is also used but does contain trace nickel, which is a problem for anyone with a nickel sensitivity. Nickel allergy is one of the most frequently reported complications across all piercing types.8PubMed. Body piercing: complications and prevention of health risks
For dermal anchors specifically, the base plate material is the critical piece because it sits embedded in tissue indefinitely. A titanium base with a titanium or gemstone top is the standard choice among reputable piercers. Some cheaper anchors use mystery-metal alloy bases that may corrode or provoke a chronic inflammatory response, leading to the anchor loosening prematurely. If you are paying for a dermal piercing and the piercer cannot tell you exactly what the anchor is made of, that is a red flag.
Aftercare Differences
The general aftercare principles for both types are similar: keep the area clean with saline, avoid submerging it in standing water during healing, and do not touch it with unwashed hands. But each type has its own practical nuances. For surface piercings, the main enemy during healing is pressure. Sleeping on a healing surface piercing on the nape or chest compresses the bar against the tissue above it, accelerating migration. Using a travel pillow to keep pressure off a nape piercing, or taping a small bandage over a chest piercing before putting on a seatbelt, can meaningfully extend the piercing’s lifespan.
For dermals, the main enemy is snagging. The decorative top sits proud of the skin and catches on everything: towels, hairbrushes, necklines, bra straps. During the healing period, many piercers recommend covering the top with a small adhesive bandage whenever you change clothes or sleep. Once fully healed, snagging is still the most common reason dermals fail, because a hard enough catch can partially dislodge the anchor from the tissue that has grown into it. Once that bond is broken, it rarely re-forms as securely.
The Regulatory Gray Area
One quirk of dermal piercings that surprises many people is their ambiguous legal status. Because insertion involves cutting into the skin with a scalpel or dermal punch to create a pocket for an implanted object, the procedure arguably crosses the line from piercing into minor surgery. The British Journal of Dermatology flagged dermal anchors as “unregulated high street surgery,” noting that the procedure involves incision and the placement of a device that becomes embedded in tissue, yet is routinely performed in body piercing studios rather than clinical settings.9British Journal of Dermatology. Dermal piercings: unregulated high street surgery?
Regulations vary widely. In some jurisdictions, dermal piercing falls under the same licensing framework as standard piercing and tattooing. In others, the use of a dermal punch or scalpel technically requires a medical license. In practice, enforcement is inconsistent, and the vast majority of dermal piercings are performed by body piercers rather than doctors. This is not necessarily a problem if the piercer is well-trained, uses sterile technique, and works with high-quality jewelry. But it does mean that the person inserting what is essentially a small implant into your skin may have no standardized training or oversight. Asking about a piercer’s specific experience with dermals, their sterilization protocols, and their preferred removal method is more important here than it would be for a standard earlobe piercing.
When a Surface Piercing Makes More Sense
Despite their higher rejection rate, surface piercings have genuine advantages in certain situations. If you want a piercing that you can remove easily and cleanly on your own, a surface piercing wins. There is no embedded hardware, no tissue ingrowth, and no minor procedure to get it out. For someone who wants the look for a specific period of time, perhaps a few years, and values a simple exit, a surface piercing with a properly shaped surface bar is the more practical option.
Surface piercings also allow for paired or symmetrical placements more easily, since the two visible ends of the bar create two visible points of jewelry from a single piercing. Achieving the same look with dermals requires two separate anchor insertions, two healing wounds, and two eventual removals. In placements where the anatomy supports a surface bar well, such as the nape or the flat area of the upper chest, the simpler approach is sometimes the smarter one.
Dermals earn their place when placement demands it, specifically in locations where there is no way to create a viable channel for a surface bar. A single gem on the cheekbone, the sternum, or the back of the neck works as a dermal and would fail as a surface piercing. The trade-off is a more permanent commitment to a more complicated piece of jewelry. For many people that trade-off is worthwhile, but it should be a deliberate choice rather than a default one.
