There’s a new cosmetic procedure in town. Kybella, previously known as ATX-101, reduces upper neck fat without surgery; it’s been heralded as the end of the double chin with expectations running high for its manufacturer, Kythera Biopharmaceuticals, Inc.

While Kybella is the first product to specifically tackle the double chin, it’s not the first beauty product to be touted as the Next Big Thing. Thanks to headlines that claim miracle fixes, it’s easy to place high expectations on new elective cosmetic procedures only to have them fall short once they hit the market.

Take Zerona, for example. This fat-busting technology uses low-level lasers to disrupt fat cells — an exciting innovation that, after the FDA gave it the thumbs up in 2010, got a whole lot of buzz.

“It makes me feel like I will fit into my bikini this summer!” one woman wrote for Huffington Post UK. Another told the New York Times that she lost 11 inches off her waist, hips, and thighs after $3,400 worth of treatments. Unfortunately, that level of success doesn’t seem to be the norm. On RealSelf, Zerona’s Worth It Rating has hit a four-year low with interest in the product decreasing by 36 percent between 2013 and 2014.

But for all the methods that fall short once the hype wears off, there’s an option like Botox — a product that has steadily gained in customer satisfaction. It’s gone from a Worth It Rating of 60 percent in December 2009 to 78 percent five years later. Even more telling, consumers stay consistently happy with the treatment in the months following their trip to the doctor’s with the product currently sitting at 80 percent satisfaction.

Below are how other highly anticipated treatments have fared. See how customer satisfaction — as determined by the consumer Worth It Rating on RealSelf — changes over time as additional consumers rate and review the specific procedure.

There’s no way to know which way Kybella will go. Will it live up to the hype, or will inflated hopes only leave people disappointed?
