I have never met anyone who agrees with me on this topic, but I love Covergirl. I use their foundation and their mascara made for blue eyes - they both work great. Also, I agree with many of you about Mac. I love their eye shadows!!
I have no favorite makeup brand. Although, here in my country there are good brands, but not so well known (like Elmiplant, Gerovital), I prefer buying L'Oreal, Maybelline or Avon products. As foundation I use Colorstay, from Revlon, because it's very good for my skin.
i have tried everything from cover girl, bare minerals and l'oreal but i always go back to Maybelline. I use a Maybelline foundation and a cover girl powder and it works great on me i love it
