I really dont think it is realistic to only use 1 product line. I personally cannot use the MAC foundation, it is way to yellow for me, and I LOOOOVVVEEE Boujious waterproof Nightclubbing mascara! Smashbox also has great silicone base primer and lip exfoliator that is actually nummy! I also like a brand of mascara by another makeup artist it is called "Mally" and oh, oh also Inglot!!! So many choices and looove their pallettes! Oh yeah, also Eve Pearl Salmon concealer!!! She's won 5 Grammys for a reason!
