Skin necrosis after a facelift occurs when portions of the repositioned skin flap lose their blood supply and die, leaving an open wound that heals slowly and can scar visibly. It is one of the most distressing complications of facial rejuvenation surgery for both patients and surgeons, yet it remains relatively uncommon in the hands of experienced practitioners. The risk is not evenly distributed, though. Certain habits, anatomical features, and surgical choices make some patients far more vulnerable than others, and recognizing the early signs can mean the difference between a small wound and a significant cosmetic problem.
Where Necrosis Typically Appears
During a facelift, the surgeon undermines and repositions a broad flap of facial skin. The areas most likely to lose blood supply are the ones farthest from the flap’s base, where circulation has to travel the greatest distance through tissue that has been separated from its original blood vessels. In practice, this means the preauricular zone (just in front of the ear) and the postauricular zone (behind the ear) are the most vulnerable locations.1Facial Plastic Surgery Clinics of North America. Avoidance and Management of Complications in Facelift Surgery These distal tips of the flap receive the least robust blood flow after surgery, so any additional compromise to circulation, whether from tension, swelling, or a patient’s underlying vascular health, shows up there first.
That location matters practically. Necrosis behind the ear is easier to hide with hair, while necrosis in front of the ear can produce visible scarring along one of the most noticeable parts of the facelift incision. Surgeons often pay extra attention to flap color and capillary refill in these zones during the first few postoperative days precisely because they are the canary in the coal mine for circulation problems.
Why Blood Supply Fails
The fundamental issue is always vascular compromise. A facelift skin flap depends on a network of tiny blood vessels in the subdermal layer to keep it alive. When the flap is elevated, some of those vessels are necessarily cut, and the remaining ones have to pick up the slack. If they cannot deliver enough oxygenated blood or cannot drain deoxygenated blood away efficiently, the tissue starts to suffer. Two distinct problems can arise: arterial insufficiency, where fresh blood cannot reach the tissue, and venous congestion, where blood enters the flap but cannot drain out. Both lead to tissue death if not corrected, but they look different early on and call for different responses.
Venous congestion tends to produce a swollen, purplish flap that bleeds readily when pricked. Arterial insufficiency produces a pale, cool flap that does not bleed. Venous congestion is generally more salvageable if caught early, because the tissue is still receiving some oxygen. One study using laser Doppler measurements found that flaps with venous congestion showed a microcirculation index that climbed more than half above its preoperative level within a week, alongside a reduced overall density of the vascular network on imaging.2Plastic Surgery and Aesthetic Medicine. Bimodal diagnosis of venous congestion in skin flaps after facelift: data of laser Doppler flowmetry and optical coherence tomography angiography That kind of monitoring is increasingly being explored as a way to catch trouble before necrosis becomes irreversible.
Smoking Is the Single Biggest Modifiable Risk
If you take away one fact from this article, it should be that smoking and facelifts are a dangerous combination. Nicotine constricts small blood vessels and carbon monoxide from cigarette smoke reduces the blood’s oxygen-carrying capacity. Together, these effects choke off the already-tenuous blood supply to a freshly elevated skin flap. A systematic review of facial procedures found that active smoking raised the risk of wound-healing complications anywhere from roughly two-fold to twelve-fold, with flap necrosis, infection, and wound breakdown being the most commonly reported problems.3PubMed Central. Review on the impact of smoking on wound healing following facial procedures
A separate meta-analysis looking specifically at aesthetic procedures, including facelifts, confirmed that smoking predisposes patients to surgical site infections, delayed wound healing, and skin necrosis.4PubMed. Current evidence on the role of smoking in plastic surgery elective procedures: A systematic review and meta-analysis The picture gets slightly nuanced in the statistical details. That same analysis found the overall complication rate after facelifts in smokers versus nonsmokers did not quite reach traditional statistical significance, likely because studies lump many complication types together and sample sizes for facelifts specifically are smaller than for procedures like abdominoplasty. But the direction of the effect is consistent and the biological mechanism is clear, which is why virtually all plastic surgeons require patients to stop smoking well before and after surgery. Most recommend at least four to six weeks of cessation before the procedure and the same afterward.
Vaping and nicotine patches are not a free pass. It is the nicotine itself, not just the smoke, that constricts blood vessels. Patients who switch to nicotine replacement products without telling their surgeon are still at elevated risk.
How Surgical Technique Influences Risk
Not all facelifts carry the same odds of skin necrosis. The extent of tissue dissection matters enormously. Broadly, facelift approaches fall into categories based on how much of the deeper muscular layer (the SMAS) is manipulated. Techniques that involve lifting a combined skin-and-SMAS flap require more dissection and produce a thinner skin layer that depends more heavily on random-pattern blood supply. A meta-analysis comparing different facelift techniques found that the SMAS flap approach had a skin necrosis rate of about 1.6%, with roughly double the odds of necrosis compared with other approaches.5PubMed. A Meta-Analysis of Complication Rates Among Different SMAS Facelift Techniques
Less aggressive techniques, such as SMAS plication or limited SMAS procedures, tend to leave the skin flap thicker and better perfused. The trade-off is that more conservative approaches may produce less dramatic or less long-lasting lifting. This is one of the conversations a surgeon weighs carefully: how much structural change the patient wants versus how much vascular risk they can tolerate given their health profile. For a nonsmoking patient with good circulation, the added risk of a more extensive technique may be perfectly acceptable. For someone with borderline risk factors, a more conservative approach can avoid disaster.
Combining a facelift with other procedures also factors in. A study examining facelifts performed simultaneously with fractional laser resurfacing found no cases of skin flap loss in a group of 86 patients, suggesting the combination can be safe when the skin flaps are handled carefully and the laser settings are appropriate.6PubMed. Facelift combined with simultaneous fractional laser resurfacing: Outcomes and complications The key variable is always how much blood supply the flap retains after everything is done.
Underlying Medical Conditions That Raise the Risk
Beyond smoking and technique, certain medical conditions can quietly increase a patient’s vulnerability to flap necrosis. Any disorder that affects small blood vessels or blood clotting can compromise flap survival. One documented case involved a patient who developed retroauricular flap necrosis after a facelift and was subsequently found to have antiphospholipid antibodies, a condition that promotes abnormal clotting in small vessels.7PubMed Central. Retroauricular Flap Necrosis Following Facelift in a Patient with Antiphospholipid Antibodies: A Possible Microvascular Thrombotic Complication This is an unusual scenario, but it illustrates why thorough preoperative screening matters.
Diabetes, autoimmune vasculitis, and connective tissue disorders can all impair the microvascular healing that a facelift flap depends on. Patients on blood thinners face a different kind of risk: not necrosis from poor supply, but hematoma from excessive bleeding, which can compress the flap and secondarily cut off its blood flow. A hematoma that is not drained promptly can cause the same downstream tissue death as direct vascular insufficiency. This is why most surgeons are meticulous about blood pressure control in the first 24 hours after surgery, since even a modest spike can trigger bleeding under the flap.
Recognizing the Early Warning Signs
Skin necrosis does not happen instantly. In the first day or two after surgery, compromised skin typically goes through a progression. The earliest sign is often a change in flap color: the skin may look darker, more purple, or unusually pale compared with surrounding tissue. Blistering can appear next, followed by a firm, dark eschar (a dry, leathery patch) over the affected area. If only the very superficial layers are involved, the damage may be limited to a small scab that eventually peels off and heals on its own with minimal scarring. If the damage extends through the full thickness of the skin, the consequences are more serious.
Temperature matters too. A flap that feels cool to the touch compared with surrounding skin is not getting adequate arterial flow. A flap that feels warm and tense, with a purplish hue, is likely congested with venous blood that cannot drain. The capillary refill test, pressing on the skin and seeing how quickly color returns, gives a rough bedside read. Slow or absent refill suggests arterial problems; instant refill with persistent purple discoloration suggests venous congestion.
Technology is beginning to supplement these clinical observations. Laser Doppler flowmetry and optical coherence tomography angiography can quantify blood flow in the flap and detect congestion patterns that the naked eye might miss.8Plastic Surgery and Aesthetic Medicine. Bimodal diagnosis of venous congestion in skin flaps after facelift: data of laser Doppler flowmetry and optical coherence tomography angiography These tools are not yet standard in every practice, but they represent a shift toward catching problems earlier rather than waiting for visible tissue death.
Treatment When Necrosis Develops
Once skin necrosis has occurred, the approach depends on the depth and extent of the damage. Superficial necrosis affecting only the outer skin layers is usually managed conservatively: the dead tissue is kept clean and moist, sometimes debrided gently, and allowed to re-epithelialize over weeks. The body is remarkably good at regrowing skin from the wound edges and from hair follicle remnants within the wound bed, so many small areas of superficial necrosis heal without requiring a skin graft.
For deeper or larger areas, several adjunctive therapies have shown promise. Hyperbaric oxygen therapy, which involves breathing pure oxygen in a pressurized chamber, has been studied specifically in facelift patients. A case-control study found that patients who received hyperbaric oxygen therapy after facelift surgery healed in an average of about 13 days, compared with roughly 37 days in a control group, a statistically significant difference.9PubMed Central. Assessing the Efficacy of Hyperbaric Oxygen Therapy on Facelift Outcomes: A Case-Control Study Comparing Outcomes in Patients With and Without Hyperbaric Oxygen Therapy The treatment typically involves sessions lasting about an hour to 90 minutes at around twice normal atmospheric pressure. Availability is a practical barrier, since not every community has a hyperbaric facility, and the cost can be substantial.
When venous congestion is the culprit and the flap has not yet progressed to full necrosis, medicinal leeches offer a surprisingly effective intervention. Leeches are FDA-approved for treating venous congestion in grafted tissue.10PubMed Central. A Comprehensive Review of Medicinal Leeches in Plastic and Reconstructive Surgery They work through a combination of direct blood removal and the injection of natural anticoagulants in their saliva, which keeps the bite wound oozing for hours after the leech detaches. This passive drainage can relieve the pressure of trapped venous blood and buy time for the flap’s own veins to recover. Timing is critical, though. Research on failing flaps has shown that survival drops sharply if venous congestion is not relieved within a few hours, making early recognition and intervention essential.11PubMed. The failing flap in facial plastic and reconstructive surgery: role of the medicinal leech
Newer wound-care approaches have also been explored. One study reported treating post-facelift flap necrosis with charged polystyrene microspheres applied to the wound bed, observing accelerated granulation tissue formation and rapid skin regrowth with no complications.12PubMed Central. Post-facelift flap necrosis treatment using charged polystyrene microspheres This is a niche intervention, but it reflects the broader push toward finding treatments that speed healing and minimize scarring once necrosis has already set in.
Platelet-Rich Plasma and Regenerative Approaches
Platelet-rich plasma, better known as PRP, has attracted attention as a potential treatment for skin at risk of necrosis. PRP is made from a patient’s own blood: a sample is drawn, spun in a centrifuge to concentrate the platelets, and then injected into the affected area. The platelets release growth factors that promote new blood vessel formation and tissue repair. A case report documented a patient with vascular compromise and impending skin necrosis after a fat transfer procedure who was treated with PRP injections over ten days, with progressive healing and prevention of full necrosis.13Clinical Case Reports. Platelet‐Rich Plasma as a Promising Treatment for Skin Necrosis and Vascular Compromise Following Fat Transfer: A Case Report and Comprehensive Literature Review
Animal research supports the biological rationale. A study in diabetic rats showed that preconditioning skin flaps with PRP injections significantly increased blood vessel growth, growth factor levels, and flap survival compared with untreated controls. Strikingly, the PRP-treated diabetic rats achieved flap viability comparable to nondiabetic rats that also received PRP.14PubMed Central. Preconditioning Local Injection of Activated Platelet-Rich Plasma Increases Angiogenesis, VEGF Levels, and Viability of Modified McFarlane Flap in Diabetes-Induced Rats Whether PRP injected at the time of a facelift could prevent necrosis in high-risk patients is an open question, and large human trials have not yet been done. But the direction of the evidence is encouraging enough that some surgeons have begun incorporating PRP into their practices, particularly for patients with risk factors for poor healing.
What the Scars Look Like After Recovery
Even with good treatment, skin necrosis almost always leaves some visible mark. The question is how noticeable it will be. Superficial necrosis that heals by secondary intention often produces a patch of skin that is slightly lighter or slightly pinker than surrounding tissue for months, eventually blending reasonably well. Deeper necrosis, particularly when it requires excisional debridement, tends to leave wider and more hypopigmented scars. One study documented patients who healed with hypopigmented, widened scars in the affected regions after debridement and prolonged wound care.15Aesthetic Surgery Journal. Local Tranexamic Acid in Facelift Surgery Is Not Associated With Wound Healing Complications: A Matched, Single-Surgeon Cohort Study
For many patients, the emotional impact of necrosis is as significant as the physical scar. A facelift is pursued for cosmetic improvement, and watching part of the result break down can be deeply demoralizing. Patient-reported outcome tools like the FACE-Q Aesthetic questionnaire have been used to measure satisfaction after facelift surgery, covering areas like scar appearance, overall facial appearance, and psychological well-being.16PubMed Central. The Use of the FACE-Q Aesthetic: A Narrative Review These instruments help researchers quantify what patients actually care about, and unsurprisingly, scarring in visible locations scores poorly even when the overall lift result is good.
Scar revision surgery is an option once healing is complete, typically after six months to a year. Techniques include direct excision of the scar, dermabrasion, laser resurfacing, and sometimes small local flaps to redistribute tension. The postauricular area is generally more forgiving for revision because hair can camouflage the result. Preauricular scars are trickier, but modern scar-management protocols, including silicone sheeting, steroid injections, and carefully timed laser treatments, can improve the outcome substantially over time.
Reducing Your Risk Before Surgery
The most effective strategy for avoiding skin necrosis is risk modification before you ever enter the operating room. If you smoke, stop completely, not just cut back, for at least a month before surgery and a month afterward. Nicotine gum and patches count. Be honest with your surgeon about your smoking history, because the physiological effects on blood vessels persist for weeks even after you stop, and your surgeon needs accurate information to plan the right approach.
Make sure your surgeon knows your full medical history, including any bleeding or clotting disorders, autoimmune conditions, diabetes, and all medications and supplements you take. Several common supplements, including fish oil, vitamin E, and ginkgo biloba, affect clotting and are typically stopped before surgery. Blood pressure control in the perioperative period is critical; uncontrolled hypertension is a leading contributor to post-facelift hematomas, which can cascade into skin necrosis.
Choosing an experienced, board-certified surgeon matters. Surgeon skill in managing flap thickness, minimizing tension on the closure, and selecting the right technique for a given patient’s anatomy and risk profile is probably the single most important variable that does not show up in studies because it is hard to quantify. Ask about your surgeon’s complication rates, what technique they plan to use and why, and what their protocol is if early signs of flap compromise appear. A surgeon who has a clear plan for monitoring and early intervention is one who takes the risk seriously. The postoperative period is equally important: follow your surgeon’s instructions about head elevation, activity restriction, and follow-up visit timing. Those first 48 to 72 hours are when most salvageable problems declare themselves, and being in close communication with your surgical team during that window gives you the best chance of catching and treating any issues before they become permanent.
