I loathe the thickening mascaras which are advertised all over the place. I tried one which consisted of white undercoat (to thicken) and black mascara to put on top. It makes my eyelashes look like pertrified spiders. It is horrible and takes an age to take off, and is all fibrous and yucky. I now resort to cheap and cheerful plain non-thickening or lengthening mascara - is so much better.
Also have tried Loreal Minerals powder - it is useless. Goes on patchy and strangely coloured.
What make up do you hate?
