I think she is talking about the make up counters brushes being dirty..
Although when I've gone to makeup counter they never use brushes on me. I guessing because they don't clean them therefore they don't use them. They usually use those wedges.
Thank you for clearing that up Moonlight, I didn't know. I actually just got the makeover done today and they did use brushes (and sponges and her fingers haha), and I bet they were dirty because the lady just sprayed a bit of water on them before she put it on my skin. Gross!! I bought a blush and lip gloss, but for me the makeup was way too heavy feeling. I hardly wear makeup and I'm not into the whole face look.
My gf uses it and it hasn't broke her out. P.S. You look like like the girl I saw in a video adult chat a couple of nights ago! Was it you?
Edit: The background on your avatar is also very similar!
I tried the makeup out today, and it was way too heavy for my skin. And no, I was definitely not the girl in the video chat.
