Perfect mix of a powder and liquid foundation. I use Smashbox primer under it and it gives an incredibly smooth appearance. Where as powders dry me out and liquid never lasts, this is the perfect mix of them both without drying out my skin or making it look too dewy. I am very loyal to MAC products and this one is probably my absolute favorite.
I love MAC Studio Tech--it's a fuller coverage makeup that doesn't look greasy or oily after a short time. I have fairly oily skin and don't like to use liquid foundation. I also use Studio Fix sometimes but this offers better coverage and, for me at least, is much easier to apply.
