my skin has got really bad recently and my normal concealer isnt cutting it.

i usually use a boots 17 one as its cheap and one of the few i can find that so yellower bases, as i am fair skinned and have yellow undertones to my skin, so most makeup is too white or too pink based for me.

i find it hard to match my skintone so that rules out a lot, plus i dont want to make my skin worse, but dont want to go out with it all red and spotty! i've trried a few thicker concealers but they didnt blend or stank of chemicals :(

i was wondering if anyone knows of any long lasting ones that might be any good and come in a range of shades?

and hopefully dont cost the earth! i'd love to try bobbi brown as she bases all her makeup on yellow tones, but her concealers ar£15 upwards which is way too expensive for me
