Best: 

maybeline dream matte mouse.  Perfect for my skin all other foundations peel of after a few hours. 

Worst: 

Rimmel London's Sexy Curves masscara.  Absolute rubbish, didn't even make my lashes look like they were curled -.- 

also the brush was very poor.

I really REALLY love Avon's Anti-acne face scrub. I don't remember the exact name of it, but it is a grainy green scrub that comes in a white tube. It's so strong that you're only supposed to use it twice a week, but I love it. It really works and it has a cool tingly sensation afterwards. :)

One Avon product I DIDN'T like was their colored mascara (again, I can't remember the name, but I'll try to update later with the names). They had two color options, green and purple, but that honestly didn't matter 'cuz you couldn't tell either way!! And I don't think it lengthened very well either, but that might be because I have really long eyelashes to begin with.

i LOVE Wet n Wild's Megalast nail polish...it has a flat and wide brush so it covers a larger area in each stroke and it covers with only one coat! i only have it in color so far but i will get more...the color i got was 'I Need a Refresh-mint" oh and it dries pretty fast!
