Overall, I think Benefit is an okay brand. Some things are amazing, while other things are pretty bad. I'll do a quick review on stuff that I have.
Hoola - Hoola is a great bronzer! It's matte and it's great for contouring as well.
Dandelion - This may be because I've got a medium skin tone, but I couldn't really get this to show up on me. It's probably a great blush for people with fair skin (pinkiecharm from youtube loves this blush), but it just doesn't work for me. I just use it to blend out blush if I've applied too much, or just to go over cream blush to set it.
Some Kind-A Gorgeous - This wasn't too bad for me. A good way to apply it is with a damp sponge. That way you don't get too much of it.
Get Even - This pressed powder is basically a mattying powder. It works fine, but I just love the way the compact looks.
Creaseless Cream Shadow/Liner - I have two. One in Get Figgy and one in Tattle Tale. They are great cream shadows for bases, and they really don't crease at all. They remind me a lot of MAC Paint Pots.
Benetint - While I really liked this buildable stain on my cheek, it didn't do so great on my lips. It settled into my fine lines, and by midday it looked like my lips were cracked and bleeding. Which, let me tell you, is not an attractive look. Another thing is that when you use the brush to apply it to your lips, it tickles, and the colour payoff on the lips isn't wonderful.
Posietint - I found that this was so much better than Benetint. It's thicker, more gel-like, so it's nicer to apply onto the cheeks. And it gives a nice baby pink glow. It's really pretty.
California Kissin' - This was expensive for blue lipgloss. While it smelled really nice (like peppermint), I didn't think it did anything for my smile. I think I've used this like ..maybe once.
Gabbi Bag - I really like this bag for carrying some stuff when I go to a sleepover or I'm doing a friend's makeup really quick and easy. There are brush holders, and it's really roomy for other items as well.
Discontinued items:
Mr. Frosty - Oh Mr. Frosty, how I hated you. It was so waxy and just a pain in the butt to sharpen and use.
F.Y.Eye - Didn't really like this one either. It didn't do anything for my lids.
Powder Eye Shadow - I only bought one colour (Blushing Bride), and it's a baby pink. The shadow was really chalky and difficult to work with.
Her Glossiness - I had one of these in Who Are You Wearing?, and while it was a really pretty colour, it smelled really bad. And I just did not like using it.
Smoooch - This is kind of like lip conditioner. I really liked it because it made my lips really smooth, but really, it was expensive for lip balm.
Sheer Cream Blush - This stuff came in a really small tube. The good thing about it is that you didn't need a lot for colour.
I'm pretty sure that's all I have. I'll update if I find that I have something else.
