Wow- this does remind me of that 10 years younger programme.
Slightly off-topic (sorry) but I used to watch that too.
They used to get someone's perceived age down by 10 years (I know: "The clue's in the name, LaMar's") but slightly sneakily, imo.
The initial age estimate was done at a distance; the subject (without makeup, bad hair, old clothes) stood in the street and people were asked, out of the subject's earshor, how old they thought they looked.
Then, after the fillers, dental work, hair styling etc, people were brought up to the (nicely made up and fashionably dressed) subject and asked to estimate their age while standing right by them and talking to them.
Yes, they looked better after the procedures, but you could tell the people asked were often knocking off a further 5 years or so in order not to cause hurt feelings.
Just as another by the by, I think that not automatically cutting and perming hair and letting it go grey helps a lot. Imagine the photo of Nigella with a grey perm and she'd easily look 60. Despite the work she's had done.
But she's a very heavy smoker too.
