When you can get plastic surgery depends on your age, your health, and what procedure you’re considering. Some surgeries are safe as early as age five, while others require you to be at least 18 or even 22. Beyond age, surgeons evaluate your weight stability, nicotine use, recent illnesses, and mental health before clearing you for an elective procedure.
Age Requirements by Procedure
In the United States, anyone under 18 needs parental consent for plastic surgery, and some states restrict certain procedures until age 21. But legal permission is only part of the picture. The real question is whether your body has finished growing in the area being operated on.
Ear reshaping (otoplasty) has the lowest age threshold. Because ears are fully developed by age five, this procedure can safely be performed on young children. Nose reshaping (rhinoplasty) is typically safe once the facial bones have stopped growing, which happens between ages 14 and 15 for females and 16 to 17 for males. Breast augmentation is a different story: the American Society of Plastic Surgeons recommends waiting until at least age 18, and the FDA prohibits silicone breast implants for augmentation in anyone under 22.
Weight and BMI Thresholds
Most plastic surgeons set a BMI limit for elective procedures. A BMI of 30 or below is the most common cutoff, though some surgeons will operate on patients with a BMI up to 35 or even 40. Very few will perform surgery on anyone with a BMI above 40, as the risk of complications during and after the procedure rises significantly at that level. These limits apply to both general and local anesthesia, with occasional exceptions for body types where BMI doesn’t reflect actual risk accurately.
If you’ve recently lost a significant amount of weight, whether through bariatric surgery or on your own, your surgeon will want to see that your weight has been stable for an extended period before performing body contouring procedures like skin removal. There’s no single number of months that every surgeon requires, but the key principle is that your body needs time to acclimate to its new weight, especially if you’re still adjusting to a post-bariatric diet. Losing or gaining weight after a contouring procedure can compromise the results.
Timing After Pregnancy
If you’re considering a tummy tuck or mommy makeover after having a baby, plan on waiting at least 6 to 12 months after delivery. Your body needs that time to recover, and your weight needs to stabilize before a surgeon can plan the procedure effectively.
Breastfeeding adds another layer. You cannot undergo a tummy tuck or breast surgery while breastfeeding because anesthesia medications can pass to your infant. For breast procedures specifically, the recommendation is to wait at least six months after you’ve fully stopped breastfeeding.
Nicotine and Smoking
Nicotine constricts blood vessels, which starves healing tissue of oxygen. This dramatically increases the risk of wound complications, infections, and poor scarring. Most surgeons require you to be completely nicotine-free for at least four weeks before surgery. That includes cigarettes, vaping, patches, and nicotine gum. You’ll also need to stay nicotine-free during recovery, so expect a total abstinence window of several weeks on either side of your procedure.
Diabetes and Blood Sugar Control
If you have diabetes, your surgeon will check your HbA1c level, a blood test that reflects your average blood sugar over the past two to three months. There’s no universal cutoff, but an HbA1c above 8% is widely considered to increase the risk of surgical complications. Some guidelines recommend postponing elective surgery if HbA1c exceeds 9%, since patients in that range are vulnerable to serious metabolic problems during and after the operation. Getting your blood sugar well controlled before scheduling a procedure is one of the most important things you can do to ensure a smooth recovery.
Recent Illness
Being sick in the weeks before your surgery date can force a postponement. For COVID-19, expert guidelines recommend waiting at least seven weeks after infection before proceeding with elective surgery, because the virus can increase complication risk even after you feel better. If you test positive within 10 days of your scheduled procedure, it will almost certainly be postponed. For common colds or respiratory infections, surgeons generally want you fully recovered before going under anesthesia, since even mild congestion can complicate airway management.
Mental Health Screening
Plastic surgeons are increasingly aware that some patients seeking cosmetic procedures have body dysmorphic disorder, a condition where someone fixates on perceived flaws in their appearance that others can barely see or can’t see at all. Among patients seeking rhinoplasty, roughly 21% meet the criteria for this condition. Among cosmetic dermatology patients, the rate is about 14%.
The challenge is that surgeons aren’t great at catching it on their own. In one survey of 265 plastic surgeons, 84% said they had unknowingly operated on a patient with body dysmorphic disorder. When tested against standardized screening tools, surgeons correctly identified the condition less than 5% of the time. This matters because people with this condition rarely feel satisfied after surgery and often seek repeated procedures. A responsible surgeon will ask about your expectations, your history with appearance-related anxiety, and whether you’ve sought surgery for the same concern before. If you find yourself constantly preoccupied with a feature that others don’t notice, spending significant time checking mirrors or comparing yourself to others, it’s worth exploring that with a therapist before committing to a procedure.
Putting It All Together
The timeline for getting plastic surgery is rarely just about picking a date. Your surgeon will evaluate several factors at once: whether you’re old enough for the specific procedure, whether your weight is stable, whether you’re free of nicotine, whether any chronic conditions like diabetes are well managed, and whether you’ve recovered from recent pregnancies or illnesses. Addressing these factors ahead of time, sometimes months in advance, is the fastest way to get cleared and scheduled. If you’re told to wait, it’s almost always because the delay meaningfully reduces your risk of a complication or improves your final result.
