Best Concealer out of these?

Go with clinique, I use it and its a real miracle worker. I used to have horrible acne but then I started going to a dermatologist, but unfortunately I was left with blemishes. I went to the mall and bought clinique because a friend said it was great and OMG she was right! I wouldn't really use Mac on a daily basis because in the long run Mac will cause you problems, as for bobbi brown I'm not sure, I have never used it. Try clinique I'm sure you will like it. Good luck!
