Dermabond Prineo is a two-part skin closure system that pairs a liquid tissue adhesive with a self-adhering mesh strip, replacing or supplementing traditional sutures and staples for closing surgical incisions. It was developed by Ethicon (a Johnson & Johnson subsidiary) and has become increasingly common in orthopedic, plastic, and general surgery settings. The device offers a genuinely faster wound closure and acts as a microbial barrier, though it comes with trade-offs that patients and surgeons should understand before assuming it is the right choice for every procedure.
How Prineo Works
The system has two components. The first is 2-octyl cyanoacrylate, a medical-grade version of the “super glue” family of adhesives. A thin layer of this liquid adhesive is applied directly over the approximated skin edges of an incision. The second component is a flexible, self-adhering polyester mesh that is pressed on top of the adhesive while it is still tacky. The mesh distributes tension evenly across the wound, while the cyanoacrylate bonds to the skin surface and holds the mesh in place. Together, the two layers create a watertight seal over the incision.1Wiley Online Library (Case Reports in Medicine).

In many procedures, Prineo is used on top of deep absorbable sutures that hold the tissue layers together beneath the skin. The adhesive-mesh combination then handles the outermost layer, eliminating the need for a running subcuticular (just-under-the-skin) suture or for staples. In some contexts, it can serve as the sole skin closure. Because it forms a seal rather than puncturing the skin the way staples do, there are no suture marks or staple tracks to potentially scar.
The Speed Advantage
The most consistently documented benefit of Prineo is how much time it saves during wound closure. Applying the adhesive and pressing down the mesh strip takes a fraction of the time a surgeon would spend on a meticulous subcuticular suture line, and the difference is substantial. A systematic review and meta-analysis found that every study reporting on closure time showed Prineo reduced it compared with traditional methods.2PubMed. Dermabond Prineo: a systematic review and meta-analysis
In one randomized trial of breast reduction patients, Prineo closure was roughly seven times faster than subcuticular suture, saving about six and a half minutes per incision.3Plastic & Reconstructive Surgery. In Search of an Ideal Closure Method: A Randomized, Controlled Trial of Octyl-2-Cyanoacrylate and Adhesive Mesh versus Subcuticular Suture in Reduction Mammaplasty A separate study of incisions in breast procedures found that Prineo closure averaged about two and a half minutes, compared with more than sixteen minutes for intradermal sutures.4Annals of Plastic Surgery. Evaluation of a New Skin Closure Device in Surgical Incisions Associated With Breast Procedures Those minutes add up. In a busy operating room, saving even five to ten minutes per case can translate to meaningful reductions in anesthesia time and room turnover.
The speed advantage is not universal across every comparison, though. In a trial following total shoulder replacement, one surgeon closed faster with Prineo than with standard tissue adhesive alone, while a second surgeon was actually faster using staples than Prineo.5PubMed.

Scar Quality and Cosmetic Outcomes
For many patients, the question that matters most is whether the scar will look better. The evidence here is encouraging in the short term but levels out over time. In randomized breast reduction trials where one breast was closed with Prineo and the other with subcuticular sutures, blinded evaluators scored the Prineo side significantly better on scar scales at the two-week mark.6Plastic & Reconstructive Surgery. In Search of an Ideal Closure Method: A Randomized, Controlled Trial of Octyl-2-Cyanoacrylate and Adhesive Mesh versus Subcuticular Suture in Reduction Mammaplasty By later follow-ups, though, the two methods looked essentially the same on standardized scar assessment scales.7PubMed Central. Octyl-2-Cyanoacrylate and Adhesive Mesh Closure System Versus Subcuticular Suture Closure in Reduction Mammoplasty: A Randomized, Controlled Trial
A study comparing scar quality at one, three, and six months after surgery found no significant differences in total scar scores between the Prineo group and the suture group at any time point.8PubMed Central. Research on Postoperative Scar Quality of Sutures and Skin Surface Adhesives The practical takeaway is that Prineo does not produce a worse scar than careful suturing, and it may look better during the early healing phase when patients are most anxious about their incision. Over the long haul, your body’s own healing biology is the dominant factor in how a scar matures, not which closure method sits on top.
Patient-reported outcomes tell a slightly more interesting story. In an abdominoplasty trial, patients who had Prineo closure reported significantly less pain, thickness, and irregularity at their scars twelve months out compared with patients closed by traditional methods.9PubMed. Use of 2-octyl cyanoacrylate together with a self-adhering mesh (Dermabond Prineo) for skin closure following abdominoplasty: an open, prospective, controlled, randomized, clinical study That is a subjective measure, but patient comfort and satisfaction with their own scar matters in practice, even if a blinded evaluator might not see a dramatic difference.
Wound Complications and Infection Risk
One of Prineo’s claimed benefits is acting as a microbial barrier, meaning bacteria on the skin surface cannot easily migrate through the sealed mesh into the wound. The cyanoacrylate adhesive layer effectively forms a waterproof film, which in principle should help protect against superficial surgical site infections during the critical early healing window. Lab testing of a similar adhesive closure system has confirmed that the sealed barrier blocks common pathogens for up to three weeks.10PubMed.

In orthopedic surgery, where wound complications after joint replacement can be devastating, the comparison with staples is revealing. A large study of hip and knee replacement patients found that staple closure carried nearly twice the odds of wound complications compared with topical adhesive closure methods.11The Journal of Arthroplasty. Complications – Other Wound Complications Are Affected by Different Skin Closure Methods in Primary Hip and Knee Arthroplasty That does not mean Prineo eliminates wound problems altogether. A retrospective study of 250 breast reduction patients closed with Prineo found major complications in about seven percent of cases and minor complications in about a third, with wound separation being the most common event.12Aesthetic Surgery Journal Open Forum. Wound Dressing and Postoperative Complications Following Breast Reduction: A Retrospective Study of 250 Patients Breast reduction is a procedure with naturally high tension on the skin closure, so these rates are not surprising regardless of method, but they serve as a reminder that no closure device is a magic bullet.
Allergic Reactions
The most distinctive risk of Prineo is allergic contact dermatitis, a skin reaction to the cyanoacrylate adhesive or possibly the polyester mesh. When it happens, patients develop a red, itchy, sometimes blistered rash along the incision line, typically appearing a week or two after surgery. The reaction can look alarming and is sometimes initially mistaken for a wound infection, which can lead to unnecessary antibiotic treatment before the real cause is identified.
A retrospective review at one large orthopedic center identified 29 confirmed cases of allergic contact dermatitis among roughly 6,000 uses of Prineo, putting the estimated incidence at about half a percent. Most of these reactions were moderate or severe, and the average time from surgery to diagnosis was nearly twelve days.13PubMed. Characterizing the Diagnosis and Treatment of Allergic Contact Dermatitis to 2-Octyl Cyanoacrylate Used for Skin Closure in Elective Orthopedic Surgery A separate case series in breast reduction patients found a rate of about 1.8 percent, and noted that the inframammary fold, where moisture and friction are present, may not be ideal for this product.14PubMed Central.

Treatment for mild to moderate reactions typically involves topical steroids and antihistamines. In one reported spine surgery case, the rash resolved with hydrocortisone cream and diphenhydramine.15PubMed Central.

Two pediatric patients developed allergic dermatitis specifically on their second exposure to Prineo after knee arthroscopy, with both cases appearing within two weeks of that repeat surgery.16PubMed Central.

Removal and Postoperative Care
One of the practical advantages patients notice is that Prineo is easy to live with during recovery. Because the adhesive layer is waterproof, you can typically shower without worrying about getting the incision wet, unlike some traditional dressings that need to be kept dry. The mesh strip stays in place for roughly two weeks, then begins to peel at the edges on its own as the skin beneath it turns over and the adhesive bond weakens. At a follow-up visit, the surgeon or a nurse peels it off, which is generally painless.17Journal of Neurosurgery: Pediatrics. Wound closure with a mesh and liquid tissue adhesive (Dermabond Prineo) system in pediatric spine surgery: a prospective single-center cohort study incorporating parent-reported outcome measures Surgeons working with body-contouring patients, where incision lines can be extremely long, have highlighted painless removal as a notable advantage.18PubMed.

If the mesh starts lifting at the edges before your follow-up, you do not need to panic. It naturally loosens as the adhesive degrades. Avoid picking at it or pulling it off forcefully, since the skin underneath may still be fragile. If a large section comes off well before two weeks, contact your surgeon’s office for guidance on whether a replacement dressing is needed.
Where Prineo Performs Best
The device shines in situations where long, clean incisions need to be closed efficiently. Body-contouring procedures after massive weight loss, abdominoplasties, and breast reductions all involve lengthy incision lines where a running subcuticular suture would take a surgeon many minutes. Prineo can cover those long incisions in a fraction of the time.19PubMed. Effective wound closure with a new two-component wound closure device (Prineo) in excisional body-contouring surgery: experience in over 200 procedures Joint replacement surgery is another major use case, where the predictable wound protection and reduced complication rates compared with staples have driven adoption.
The device is less suited to areas with a lot of moisture, friction, or movement. The manufacturer’s own labeling cautions against use in those zones, and the higher reaction rates seen in the inframammary fold support that warning.20PubMed Central. Rash with DERMABOND PRINEO Skin Closure System Use in Bilateral Reduction Mammoplasty: A Case Series Wound edges that cannot be well-approximated before applying the adhesive are also poor candidates, since Prineo holds skin edges together rather than pulling them into alignment the way deep sutures do. It is a surface closure, not a structural one.
Cost Considerations
A single Prineo kit costs meaningfully more than a package of sutures or staples. One economic evaluation estimated the unit cost at around $79, which is a significant premium over traditional closure supplies.21Journal of Orthopaedic Experience & Innovation. The Cost-Effectiveness of Wound Dressings for Infection Prophylaxis in Total Joint Arthroplasty: An Economic Evaluation However, hospitals do not evaluate cost in isolation. They factor in operating room time, postoperative visits, and wound complication rates.
A budget impact analysis modeled what would happen if a hospital performing 500 joint replacements per year switched to Prineo. Despite the higher material cost, the analysis predicted net savings of roughly $57 to $80 per patient, driven primarily by reduced postoperative healthcare visits and fewer dressing changes. Across a full year, that translated to estimated savings of about $28,000 to $40,000 for the hospital.22PubMed Central. A US hospital budget impact analysis of a skin closure system compared with standard of care in hip and knee arthroplasty Whether your hospital or surgical center has done this math and passed the decision along to your surgeon varies widely. From a patient’s perspective, you are unlikely to see a separate line item for the closure device on your bill, since it falls under the general surgical supply cost bundled into the procedure.
Prineo in Pediatric Surgery
Children present a unique challenge for wound closure. They tend to be less cooperative with dressing changes, more likely to pick at sutures, and more distressed by staple removal. Prineo sidesteps several of these issues. A study of pediatric spine surgery patients found that the mesh peeled off on its own or was removed painlessly at a routine follow-up about two weeks after the operation, with parents reporting positive experiences.23Journal of Neurosurgery: Pediatrics. Wound closure with a mesh and liquid tissue adhesive (Dermabond Prineo) system in pediatric spine surgery: a prospective single-center cohort study incorporating parent-reported outcome measures The waterproof barrier also means fewer restrictions on bathing, which matters a great deal to families managing a child’s recovery.
The allergic reaction concern applies to children too. The two reported pediatric cases of allergic contact dermatitis both occurred on re-exposure, suggesting that if a child had Prineo used in one surgery and then needs another procedure, the surgical team should be told about the prior exposure so they can watch for or avoid a repeat reaction.24PubMed Central.

Questions to Ask Your Surgeon
If you are scheduled for a procedure and want to know whether Prineo will be used, or whether it should be, a few practical questions are worth raising. First, ask whether you have any known sensitivity to cyanoacrylate adhesives or whether you have had a skin reaction to any surgical adhesive in the past. A prior reaction to standard Dermabond (which uses the same adhesive without the mesh) is a meaningful red flag.
Second, ask where the incision will be and whether it falls in a high-moisture or high-friction area. If so, your surgeon may prefer a different closure approach. Third, ask about the plan for dressing changes and removal. One of the practical perks of Prineo is that it typically stays in place without needing to be changed, and patients can shower over it. If your surgeon uses Prineo, you may have fewer wound care tasks to manage at home compared with a traditional dressing that needs regular replacement.
Finally, if you are having a revision surgery or a second procedure in the same area where Prineo was previously used, make sure your surgical team knows. The sensitization risk with repeat exposure is real, and your surgeon may opt for sutures or a different adhesive product the second time around to avoid an unnecessary allergic reaction during your recovery.
