Just a quick link in case you missed it elsewhere: if you're interested in the chemistry of makeup, like I am, you should be sure to read this piece about lipstick formulas on Motherboard. (I'm really fascinated by this stuff.)
Also, while I'm at it, I should mention what I discovered when I went to Sally Beauty to use my $5 coupon that I got for renewing my Sally card, and that's that all Seche topcoat & basecoat was buy one, get one free. (Also all of the red-tag stuff that's usually by the door at my Sally's was an additional 50% off the marked price!) I said I wasn't going to buy any more Seche Vite unless I found it on sale, but it was, so I did. I should be good for a while now.
