Luvly app - face yoga - any good?

[1stWorldProblems]

My newsfeed keeps advertising an app called Luvly that promises facial exercises to improve your facial & neck tone. I'm very happy with my 52 year old body apart from my saggy second chin / neck and would like to get rid of it.

So has anyone used it? Does it work?

I was toying with face yoga last week (would not pay for an app though, just anything on YouTube etc). During that pondering I came across this article which basically killed off the idea for me, there are mild benefits but you need to put in a lot of consistent work.
