I never dismissed any scientific opinion, but there is severe selective editing by the BBC.
Whilst I assume that Professor Regan knows more about skin than me, she is
Clinical Professor
Division of Surgery, Oncology, Reproductive Biology and Anaesthetics
Perhaps I'm being dim, but why, exactly was she brought in to a programme on skin ?
There are many skin experts in this country, why her ?
Not surprising she doesn't have a conflict of interest is it ?
The legitimate suspicion is that although an eminent scientists, she was chosen because her views happened to be the one the arts graduates had scripted.
Not saying for a second that she's dishonest, but that the art of pseudo-science programmes is to pick the one with the sexiest view.
I could have told you that a cheap cosmetic would have come out well without consulting a professor of anything. Indeed with no knowledge of skin in any way.
There is absolutely no chance that a BBC programme of any kind, let alone Horizon is going to say "actually the 117 quid a bottle stuff is the dog's bollocks".
It makes "better TV" to have the "surprise" that the cheap stuff does better than the expensive one.
You don't even have to lie, just be very selective on what you test.
Then find an academic who is articulate and shares the conclusion you reached before you shot one frame of film.
