Jeunesse, that someone mentioned above, reminds me of a friend of a friend on Facebook. I don't know this person, but they are related to someone I know. I only see their posts when my friend comments on them.
This person used to do teeth whitening, but has no qualifications, it was some sort of franchise thing. Then that stopped suddenly, and they were pushing jeunesse, using their relatives for photos of before and after.
They then said that they had a new product coming out, Zen bodi, and they showed a photo of someone who had used it and lost three stone in five weeks! This was quite a while ago, and it was when I started reading about MLMs on MN. I realised that it was an MLM, and this person was saying boss babe all the time, which I had not seen before.
All of a sudden, all these posts were deleted from their Facebook page, and this person was going to train to be an airline pilot. Nothing seems to have happened there. Their page is full of fake it until you make it - there are posts of new luxury cars, and then friends commenting that it's not actually their car. Photos of lovely hotels, and then comments from others asking what the hotel was like, and this person says that they didn't actually stay there.
Now, they are starting Maëlle. 
I feel sorry for this person, moving from one useless scheme to another, but thinking that they are hugely successful.
