Roughly 2% to 6% of cosmetic procedures result in a medical complication, depending on whether you count per procedure or per patient. That range comes from large outcome studies tracking thousands of surgeries performed by board-certified plastic surgeons. Most of these complications are minor and treatable, but “going wrong” means different things to different people, from a life-threatening emergency to simply being unhappy with the results.
Overall Complication Rates
A review of more than 7,100 cosmetic procedures found a complication rate of 2.2% per procedure and 6.2% per patient. The per-patient number is higher because many people have multiple procedures done at once, and more procedures mean more chances for something to go sideways. These figures are consistent with other large studies from accredited U.S. surgical centers.
The vast majority of complications fall into predictable categories: fluid collections under the skin (seromas), bruising that requires drainage (hematomas), minor infections, and scarring issues. Serious complications like blood clots, organ damage, or anesthesia reactions are far less common.
Infection Risk Is Lower Than You’d Expect
Surgical site infections are one of the complications people worry about most, but the actual numbers are reassuringly low for procedures done in proper settings. A large U.S. study covering more than 5.5 million office-based plastic surgeries found an infection rate of just 0.06%. Even in studies with smaller sample sizes, the rate rarely exceeds 1% to 2% for straightforward cosmetic procedures. Complex surgeries carry higher risk, with one study finding a 1.42% infection rate for complex closures compared to 0.06% for simpler ones.
Complication Rates by Procedure
Liposuction
Liposuction carries a higher overall complication rate than many other cosmetic procedures. A systematic review and meta-analysis found a 12% complication rate when liposuction was performed on its own. The most common issues were contour irregularities (uneven or lumpy results) at about 2%, fluid collections at 2%, infections at 1%, and skin discoloration at 1%. Most of these problems are correctable, but they can require additional procedures or extended recovery time.
Rhinoplasty
Nose jobs have an inherent revision rate of about 9%, meaning roughly one in eleven patients ends up going back for a second surgery. That number is worth unpacking, though. Only about 10% of those revisions are for functional problems like difficulty breathing. The remaining 90% are driven by cosmetic preferences, where the patient wants a different look than what they got. The most common revision is scar correction, accounting for over half of all secondary procedures. So while the “redo” rate sounds high, most of these aren’t emergencies or medical failures.
Breast Augmentation
Breast implants are not lifetime devices, and the longer they stay in, the more likely problems become. At the 10-year mark, silicone implant rupture rates range from about 9% to 18% depending on the implant type and whether the surgery was a first-time augmentation or a revision. Capsular contracture, where scar tissue tightens around the implant and causes hardening or pain, is even more common. Studies have found that contracture and calcification rates approach nearly 100% in implants that have been in place for more than a decade. This doesn’t always require treatment, but it’s a near certainty that implant patients will eventually need additional surgery.
Brazilian Butt Lift
The Brazilian Butt Lift has the highest mortality rate of any cosmetic procedure, primarily because of the risk of fat entering the bloodstream and blocking blood flow to the lungs. South Florida alone recorded 25 deaths from this complication between 2010 and 2022. Safety guidelines introduced in 2018 and 2019 required surgeons to inject fat only into the layer just beneath the skin rather than deeper into muscle, where the risk of fat embolism is greatest. By 2019, the estimated mortality rate had dropped to about 1 in 15,000 procedures. That’s still higher than other common cosmetic surgeries, and notably, 14 of those 25 Florida deaths occurred after the new safety rules were published, suggesting compliance has been uneven.
When Results Disappoint Without a Medical Complication
For many people searching this question, “going wrong” doesn’t mean a surgical emergency. It means waking up and not liking what they see. Research consistently shows that most cosmetic surgery patients are satisfied with their results, but a meaningful minority are not, even when the surgery went exactly as planned from a technical standpoint.
Certain factors make dissatisfaction more likely: being young, being male, having minimal physical deformity to begin with, pursuing surgery to fix a relationship, having unrealistic expectations, or having a history of depression or anxiety. People with body dysmorphic disorder (BDD), a condition involving intense preoccupation with perceived flaws that others can barely see, fare particularly poorly. In one study, 76% of BDD patients were dissatisfied after cosmetic procedures. Surgeons who operated on BDD patients reported that in 43% of cases, the patient’s fixation on the perceived defect actually got worse after surgery. Only 1% were considered free of symptoms afterward.
This is one of the most important and overlooked ways plastic surgery “goes wrong.” The operation succeeds, the healing is normal, and the patient is still unhappy. In some cases, the experience triggers new psychological distress rather than relieving it.
What Drives the Risk Up
The single biggest factor in complication risk is who performs the surgery and where. Board certification in plastic surgery, an accredited operating facility, and proper anesthesia monitoring are the baseline requirements that keep complication rates in the 2% to 6% range cited in major studies. When any of those elements are missing, risk climbs sharply.
Combining multiple procedures in one session also increases risk. Having a tummy tuck, liposuction, and breast augmentation all at once means longer time under anesthesia, more tissue trauma, and a harder recovery. Each added procedure compounds the chance that something will need medical attention afterward.
Medical tourism is another variable. While one large study of a Joint Commission-accredited facility abroad found complication rates comparable to U.S. benchmarks, this is not representative of the broader medical tourism landscape. The CDC has documented clusters of deaths among U.S. citizens traveling abroad for cosmetic surgery, particularly to the Dominican Republic, without reliable data to even calculate a death rate because the total number of procedures performed is unknown. The problem isn’t that surgery abroad is inherently dangerous. It’s that patients often can’t verify credentials, facility standards, or emergency protocols the way they can at home, and follow-up care after returning is fragmented.
Putting the Numbers in Context
A 2% to 6% overall complication rate means that the large majority of cosmetic procedures go smoothly from a medical standpoint. But “smoothly” and “perfectly” are not the same thing. If you include revision surgeries, implant replacements, and patients who are simply unhappy with how they look, the percentage of people whose experience doesn’t go as hoped climbs considerably higher. For a procedure like rhinoplasty, nearly 1 in 10 patients will go back for a second surgery. For breast implants, the question isn’t whether you’ll need another procedure, but when.
The risks are real but quantifiable, and most of them are manageable when surgery is performed by a qualified surgeon in a proper facility. The complications that tend to cause lasting harm, like fat embolism during a BBL or severe capsular contracture years after implant placement, are procedure-specific. Understanding which risks apply to the specific surgery you’re considering matters far more than looking at a single overall number.
