"My favorite beauty product of all time is Dior Addict Lipstick in Diablotine -- it's the perfect your-lips-but-better shade. The formula plumps lips (without the peppermint sting) with a unique shiny finish. It has 25 percent less wax in the formula than most other lipsticks, which cuts down on the dated, dry look some lipsticks impart. I personally hate the sticky, wet feeling of lipgloss, but definitely love the sheen of it. This lipstick is the perfect combination of pigment and a glossy finish, without the goopy gloss feeling." --Kelly Searle
"Most people would look at this purple eyeliner and think it's a color for a night out, but it's an everyday staple for me. With dark eyes and dark hair, black eyeliner has never looked daytime appropriate on me, and I just haven't found a brown eyeliner I like. This purple shade is the perfect pop of color to make my eyes stand out without making me look like a raccoon. The unusual color always draws compliments and I never have to worry about it smudging down my face. Even after swimming, the product still stays on until I scrub it off." --Hayley Mason
"If I could only hold on to one thing from my makeup bag, it would be this liquid lip color, hands down. It has everything that's great about a lipstick and a lip gloss all in one tube. The lip color end is super pigmented, goes on creamy, and once it hits your lips, takes on the finish of a matte lipstick. Sometimes I'll stop there, but for the perfect red lip, I'll use the gloss end, which really seals in the color and has an amazing shine. The most impressive part is that this stuff does not budge or fade. At. All. By the end of the night, I have to resort to makeup remover wipes. And, one tube of Aqua Rouge has lasted me over a year because I never have to reapply!" --Erica Smith
"This little pencil went missing recently and I just about lost my mind. That's when I knew it was officially 'beauty product love.' The long-wearing pencil can draw fine lines where my brows are sparse, and the spool brush on the tip has perfect blending power to soften the edges and make me look natural. At this point I really should buy a backup. Or three. A daily must-wear for me." --Beth Mayall-Traglia
"I don't wear a full face of makeup every day. But with BareMinerals, even when I apply it in a way that gives me full coverage, I feel as if I'm not wearing any makeup at all. This is my can't-leave-the-house-without product, whether I'm going to work or out for drinks. It's so light and natural-looking, I almost forget I'm wearing it. Even without other makeup -- mascara, eyeliner, or lipstick -- I feel confident sweeping a little of this powder onto my face and walking out the door. It's the one product that I stockpile, so I never run out." --Tiffanie Petett
At TotalBeauty.com, we're (surprise!) total beauty-hoarding junkies. While this means we're constantly running out of counter space (and under-the-sink space, and medicine cabinet space, and pretty much every other space our roommates and significant others allow us), it also means we know what we like. And when we really like something, we find it hard to live without it. Case in point: One member of our editorial team recently bought an entire case of mascara on eBay after she found out it had been discontinued. Turns out, we all have a product we'd secretly like to stockpile in a beauty fallout shelter. Do you have a product you can't live without? Let us know in the comments below, and click ahead to see the one product we just won't give up.
