I have a concealer brush from the body shop but it doesn't really help apply concealer very well and I saw someone the other day apply it with a thicker brush. What is the best way to apply it? I use Bobbi Brown [[http://www.bobbibrown.co.uk/product/2335/15905/Makeup/Face/Correctors-Concealers/Corrector/New-Shades/index.tmpl corrector]] and [[http://www.bobbibrown.co.uk/product/2335/15950/Makeup/Face/Correctors-Concealers/Creamy-Concealer-Kit/Award-Winner/index.tmpl concealer]]
