Just three months ago we talked to Stamford, Conn., dermatologist Omar Ibrahimi about Kybella, an injectable zapping chin fat approved by the U.S. Food and Drug Administration in April, and already another option is hitting doctor’s offices to do away with double chins. Zeltiq Aesthetics, the company behind CoolSculpting, a non-surgical procedure that destroys fat by freezing it, has introduced an applicator called the CoolSculpting Mini to target small pockets of fat, including the ones that intractably cling to your craw. If you’re confused by the surplus of choices, you’re not alone. It’s great that there’s a growing repertoire of fat-busting solutions for those of us who don’t want to go under the knife, but the pace of innovation puts iPhone updates to shame. To clear up any confusion, we called up Ibrahimi again, and he generously took the time to set the record straight on the duo of double chin busters.
