First post! lol...
Anyways figured I would add in my 2 cents into this since I picked up this foundation last Friday...
They matched me in the store to a NW20, and I also picked up the pressed blot powder (since I normally needed to fix up my foundation during the day using my old pressed powder (haven't had to make any touchups with SFLiquid)), although I might try out the loose powder as well.
Couple of things I have noticed while using this for the last 4 days...
Less is More... I've been getting used to liquid application since it's been forever since I've used a liquid foundation. I found that I've been having better luck placing just a little dot in my mixing pan that my brush completely absords, rather than enough to have foundation remaining in the tray after the first pass.
This way I can get a very fine(thin) layer on my face (I was having trouble with the, "mask effect" that liquids tend to give, and I hate looking like I'm wearing foundation). By keeping the amount of SFLiquid on my brush very light, I've been able to eliminate looking like I'm wearing foundation, but I'm still getting complete coverage.
This also eliminated the "darkness" I was getting while initially using the product. When I was matched in the store, i looked great, but when I did it myself for the first few times, I thought that my NW20 was a shade or two too dark for my skin. Once i figured out how to apply less foundation, the color of my NW20 lightened up (it matches my skin now). Plus the blot powder lightens the foundation as well.
I'm also using a 187 to apply this foundation.
So thats my expierence... So far i'm loving it, haven't had to touchup my foundation at all while I've been at work. I think with anything, application is key. Since with a liquid, it's a lot easier to apply too much. Go for less, since you can always apply more.
