According to the American Society for Aesthetic Plastic Surgery (ASAPS), plastic surgeons performed a total of almost two million surgical procedures in 2015, up seven percent from the year before. And the plastic surgery craze shows no sign of slowing down: The number of cosmetic procedures women undergo has increased by over 500 percent since 1997, when the ASAPS began tracking this data.

But with the boom in people going under the knife, are there any that plastic surgeons would actually recommend against? ASAPS talked with plastic surgeons to get their opinions on the types of surgeries they’d advise patients to pass on.
