What is a Y Lift?

Can someone please explain to me how a Y Lift works? Is it a scam?

The Y lift is not a scam. I had it done and can tell you it will certainly lift your cheeks and jawlines, making your face appear fuller. It does what it says it will do, but the results are temporary. It's not cheap and you'll have to return to the doctor at least once a year to maintain your appearance. I also felt like I looked a bit overfilled. Other friends of mine who have it done looked great though. I think it really depends on the skill of the doctor doing it.
