In 2016, U.S. consumers spent more than $16 billion on cosmetic plastic surgeries, according to the American Society of Plastic Surgeons. Breast augmentation procedures, usually breast implants, accounted for the largest number of cosmetic surgeries that year: nearly 300,000.

Despite the high cost of such procedures, many consumers fail to do their due diligence in finding the right physician for their operation. In recent years, a growing number of doctors who aren’t board-certified in plastic surgery have started doing cosmetic procedures, and many of them are good at marketing.
