I can't get two of my favourites - Benefit Erase Paste (now Boing brightening concealer) in shade 3 or the Armani Master Corrector. They appear to have been discontinued.
Please tell me about your best under eye correctors.
I have tended to favour a corrector over a concealer as the concealer needs to be quite full coverage to give me the look I want whereas a little bit of corrector really hides them for me.
