Have you ever heard the term "turkey neck"?

It's an unflattering term for the loose skin that forms underneath the chin with age.

And according to skin experts, it can add years — and even the illusion of excess pounds — onto a person's appearance (even if they otherwise look youthful and slim).

But what if you could reduce that flabby extra skin, quickly and easily, by making one small change to your daily routine? (And no, we're not talking about surgery or injections.)

For months, rumors have been circulating about a mysterious do-it-yourself method that helps tighten the appearance of sagging skin, on the neck, face, and anywhere else it forms.

But exciting as this sounded, it was impossible to confirm, because — while numerous people claimed to know how it was done — no one seemed willing to share the details.

That is, until last week, when a world-famous plastic surgeon posted this video on the internet.

In it, he explains the rumored "skin-sculpting" secret from beginning to end (complete with instructions), allowing women everywhere to finally try it for themselves.

The verdict? Believe it or not, this skin firming technique is no joke. For one, it's so easy anyone can do it in a few seconds a day... and it also works on any type of drooping skin (whether it's your neck, cheeks, under-eyes, or even flabby upper arms).

If you'd like to try this innovative "tighter skin" technique at home, you can view the instructional video in its entirety below. It's a fascinating presentation (even if you don't have sagging skin).
