If you want proper liquid eyeliner (rather than a pencil/felt tip), I can highly recommend Bourjois Ligne Precis (or something like that) - it says it lasts 16h and it really does. No flake, no disappearing into your face. It's a nice dark brown but most definitely not black. Haven't work black mascara/eyeliner for years - it looks horrid on me.
Well I have gone out and bought facecloths and a load of stuff from REN (because they sell it in M&S and I had a 20% off voucher plus £5 off a £30 spend plus some other money off things so it didn't financially cripple me as much as it could have).
I shall report back. If I don't glow, I'm going to be bloody cross
