So I had just gotten paid & decided to visit the Ulta in the shopping center that I work in. I asked one of the ladies there if there was a good full-coverage concealer she could recommend for hiding under eye circles & she immediately suggested Boi-Ing... I asked her to apply it on me so that I could see what it looks like. I was impressed by how much it covered my dark circles/bags under my eyes.. I am so glad that I decided to spend the $20 on this... I have tried sooo many drugstore concealers & none of them could fully hide my dark circles or bags. I am really impressed with this concealer. The only con is it's quite dry,, so you have to moisturize first then apply it, or rub really hard with your finger to get a lot out of the jar. But that's okay, I'll deal with it because this stuff is worth the price & moisturizing first in order to get the best result. I usually apply 2-4 coats of this just to ensure the coverage. I wear True Match by Loreal as my foundation, which adds to the coverage. I would recommend this concealer if you don't mind the $20 price. I usually don't buy expensive makeup but I have two jobs now so I could afford to splurge a bit :) Btw, I don't get why someone said they do not recommend for under eye because it works SO WELL for me and I have horrible dark circles, but you'd never know with this stuff on!!! Well yeah, this stuff works really well!! I love Benefit !
