I use one of Avon's. Pretty cheap and does the job. I mainly use it to cover up redness from blemishes, it's a green one. I'm not sure it'd work for undereye though, I think for those you have to go skin coloured concealer.
i use a laura mercier foundation stick to cover up blemishes and set it with my trish mineral powder. undereyes i also used trish. its more natural on me then mac. problem is i thinki put too much becuase it catches in my crease.
Thank you guys! I need more makeup as I get older, to look like I'm wearing less! I ordered some Armani last night after reading lots of reviews-will let you all know!
