• As product reviewers, we get to try a lot of fun, new beauty products. 
• So, if we use something down to the last drop, it's a sign we think that product is pretty great. 
• I asked my teammates to tell me about their empties — the makeup products they love so much, they've used up the whole container. You can find these fan favorites, and why we love them so much, below.

As a style and beauty reporter, I am constantly trying new skincare and makeup products for the sake of reviews. This means that I rarely get to finish an entire product before I'm onto the next one. So, when I use a product to its entirety, you can be sure it's one I really love. 

I reached out to my teammates and fellow product reviewers to learn about the beauty products they've actually used the whole container of. Collectively, these count as some of our favorite products around. From splurge-worthy to budget beauty buys, this list covers it all.

Stila Kitten Eyeshadow Compact

Stila Kitten Eyeshadow Compact, available at Ulta, $18

I love multifunctional makeup and for that reason, Stila Kitten has earned my product loyalty. For something so compact and small, it's surprisingly versatile, standing as its own eyeshadow or blending well with different matte colors. As a neutral brown, it's universal and perfect for everyday wear, but features just enough shimmer for when you want to up the ante. It also duals as a sheen highlighter, which I like to apply on my cheekbones, nose bridge, and cupid's bow. — Dominique McIntee, former Insider Reviews editorial fellow

Chanel Ultrawear Foundation Compact

Chanel Ultrawear Foundation Compact, available at Nordstrom, $60

I own a ridiculous number of makeup and skincare products, so I rarely use the last bit of any product before starting to experiment with something new. But this is one of the few things that I shell out for on a regular basis, and have for probably seven or eight years now.

A good powder foundation is hard to find, and Chanel's gives you full coverage that's easy to apply and makes your skin look airbrushed. I'm always impressed by how fresh it still looks at the end of the day. I've tried to switch because of the price tag, but I always go back, and I'm almost instantly met with questions about what foundation I'm using. — Ashley Phillips, Insider Reviews editor

Covergirl Full Lash Bloom Mascara

Covergirl Full Lash Bloom Mascara, available at Walmart, $6.17

I'm generally someone who will use whatever is on sale when it comes to makeup. Oh this blush is cheaper? Sure, I'll try that. I have a coupon for this eyeliner. Cool, we're using this now. But one of the few makeup products I use religiously is the Lash Bloom mascara.

I love this product because it lengthens and volumizes using just one single classic "petal-shaped" brush. Its mousse formula is made with natural beeswax and designed to provide full lashes without that hard, crunchy feel. Plus, after about a month of use you'll really start to appreciate that waxy ingredient — no more flakey, spider lashes. The only thing I would say is if your lashes lack curvature, using a simple eyelash curler before application makes all the difference. — Francesca Rea, Insider Reviews producer
