I adore Benefit. I think their packaging is designed to appeal to a different age group than me, but think they have some wonderful products. I swear by They're Real mascara. Hoola is by far the best bronzer I have ever tried on my fair skin. The Boi-ing concealer is perfect for red blemish scars. Any Oxygen wow is my second favorite foundation (behind makeup forever ultra HD) and the one I use the most when it's really humid and sticky out. I've tried a few Benefit products that I wouldn't buy again, but the ones I mentioned are all repeat purchases for me. (Except Hoola, which lasts forever so I haven't needed to buy a new one yet.)
I'm going to try their new air patrol eye primer soon. The Kat Von D primer I have is great, but too yellow for fair skin. Urban Decay's is good, but I like trying new products.
