How have I never seen this thread before???
I have amazing skin so I don't use foundation or concealer but I am a HUGE eye makeup and lip gloss junkie.
I'd been using different brands of liquid eyeliner ever since I started wearing makeup (I think I was like 12 or 13) up until recently when I got a free Sephora eyeliner pencil, and omg. I love it! They're all I use now and they're about a dollar each. About a month before I got the free pencil I bought a set of Urban Decay pencils (one of their 24/7 sets, I think it was HiFi) and those were really good as well. The only thing I had a problem with is the black eyeliner didn't "glide" as well as the rest of them, so it didn't look as good, and that kinda sucked.
I have since moved on to gel eyeliner, my favorite is Urban Decay's Ink for Eyes, and a good cheap gel eyeliner is Maybelline's product (I forget the exact name). It looks just as good but it doesn't last as long.
And now mascara
I have nonexistent eyelashes and I have spent sooo much money trying to find a good mascara. I've tried pretty much everything from drugstore brands to higher end brands of mascara, and I didn't find anything satisfactory until January when I went on a little makeup spree and found Lash Injection by Too Faced. It's awesome because it builds little tubes around each lash and those tubes stay until you wash them off and the look is so dramatic and pretty. They almost look like false lashes, but not really.
As far as eyeshadow goes, my favorite brand by far is Maybelline's Eyestudio line. My current favorite pallet is called Ivy, and it has the most gorgeous colors ever. I also love Loreal's HIP loose pigments.
Ah, and lipgloss. I am currently in love with Stila's lip glazes and this one VS Beauty Rush gloss, but my favorites are the CO Bigelow Mentha Lip Shines and Carmex
Yay makeup!!
