No sunscreen every day? And never over SPF 20 ever???
No red meat or dairy?
You only get what you pay for with skincare and you need to be spending £40.00 - £60.00 if you want a decent cleanser???? 
Really???
I'm sorry, but that's just rubbish. Liz Earle Cleanse and Polish and Avene Extremely Gentle cleanser are two of the best at only £12.00 each. And as for no sunscreen...
This woman is not a dermatologist. She's a 'beautician' who's worked in the industry for a long time (and clearly has a lot of contacts.) She has no medical qualifications as far as I know and some of her advice would have a decent derm tearing their hair out.
