Oh god, there are so many!
YSL Touche Eclat Highlighter (insipid pink crap) - use Collection 2000 conc instead
EL Doublewear Light (orange crap) - use Collection 2000 long wear fndtn or Revlon Colourstay instead
Sisley Oil Free Foundation (£60 of orange crap) - use Bobbi Brown Long Wear instead
Sisley Flower Mask (£70 a tube, feted by Lisa Eldridge DID NOTHING) - try Eucerin Face Moisturiser instead
EL Advanced Night Repair (did nothing) - try Melvita Extraordinary Water instead
EL DW Powder Foundation (orange powdery crap), Lancome Powder Foundation (white powdery crap) and Stila Powder Foundation (beige powdery crap) all a waste of money - try Body Shop One Step powder foundation instead, a much better product
Any Smashbox primer - (none did a thing on me) - try Bioderma Pore Refiner instead (brilliant product)
Bobbi Brown Tinted Oil Free Moisturiser (slimy orange crap) - try Skin79 BB cream instead
Any pricy eyeshadow pallettes - try MUA pallettes at £4 a pop, fantastic
Armani Matte Lipstick (no, I do not want lips that are shiny around the edge and matte in the middle thanks) - use instead Rimmel Matte lipsticks
Urban Decay Pore minimising products (useless) - Bioderma Pore Refiner or Boots Matte Makeup Base
La Prarie Anti-Aging Foundation (worst foundation I've EVER used, £60) - MUA Matte Foundation at £2 is a massively superior product but without SPF
Very sobering when I think how much money I've spent on upmarket products that have turned out to be poor-performing compared to cheaper alternatives that provide a superior result. The french pharmacy brands (Eucerin, Bioderma, La Roche Posay) are such good value for money and seem to perform better than the big high st names, dominated by EL and Lancome houses. Hmmm.
