Since they no longer make Studio Seamless, I bought this.  It is a lighter coverage, but covers nicely and leaves a smooth, soft finish with just a tiny bit of radiance.  Color has always been a challenge for me, but the Fair F1 works well on my almost colorless skin.  The finish is pretty flawless as far as pores go, liquid formula spreads easily and is truly buildable if you want to go heavier.  I've had it on now for 9 hours and my skin still looks nice, and unlike the Studio Seamless, I do not look or feel like I am wearing foundation, but the coverage is perfect for me.  My skin is normal and no blemishes, a few extremely fine lines; it looks like my skin, only better.  I'm not even wearing blush (which I hate) since my natural pink cheeks are not obliterated by the foundation.  Dare I say, HG???  Too soon for that!
