I am obsessed with things that sparkle and shine so, natch, one of my favorite beauty products is highlighter. As a beauty editor, I was lucky enough to get my hands on Maybelline Master Strobing Stick, $11.99, a month before it launches in stores this July -- and I've been wearing it every day since.

It was love at first swipe, and, like anyone in the throes of a new romance, I talked, texted, SnapChatted and Instagrammed incessantly about it. What makes it so good is the formula: It's creamy, blends right into skin and contains just the right amount of shimmer for a strobed look. The stick format makes it ultra easy to swipe on my cheekbones; I use my finger to pat it under my brows, in the inner corners of my eye and, if I'm going out, down my nose and above my Cupid's bow. It also looks amazing in photographs and IRL, which is a big plus in my book. This relationship is simply meant to be.

If there's one thing I love, it's a sexy smoky eye.

Yup, I'm the girl you see rocking night club makeup in the middle of the day -- but I just can't help myself. There's something alluring about dramatic eyes. So you can imagine how stoked I was when the answer to my perfect-smoky-eye-every-time prayers landed on my desk: The Palladio Fifty-Fifty Cat Eye Liquid Liner + Smoky Kajal, $15.00.

My infatuation started when I realized I could create a smoky eye in under five minutes with this eyeliner. Plus, the dual-ended liner gives me options. The liquid liner on one end provides an even, blunt line for dramatic eyeliner, and if you struggle with your cat eye, the steady application brush will help you achieve a straight line. On the other hand (or end rather), the kajal pencil blends beautifully into the skin. I like to gently sweep a blending brush across my top and bottom liner for a flawless smoky look around the eyes. The best part? At under $20, it doesn't break the bank. I couldn't have asked for a more purrrfect match.

Confession time: I hate wearing sunscreen -- which is basically a cardinal sin when you're a beauty editor.

Yes, I know that sunscreen protects my skin, prevents premature aging and wards off skin cancer. Still, it's hard to get jazzed about applying the stuff. The sunblocks of my youth either left my skin slick and smelling like a coconut, or sticky and coated in a white cast that stained my swimsuits. They were a chore to apply -- and then to have to re-slather every two hours? Hard pass.

Thankfully, sunscreen has come a long way in recent years. Case in point: Kiehl's Sun Protector Water-Light Lotion for Face and Body, $29, which isn't just tolerable -- I actually enjoy putting it on. True to its name, this lightweight lotion-like formula absorbs immediately upon touch, leaving my skin feeling soft, never greasy. Between the barely-there texture and fragrance-free formula, it's kind of like wearing nothing at all. And most importantly, it gets the job done: It recently kept me burn-free after a weekend of swimming and pool-lounging in 100-degree weather.

It goes without saying that Kiehls' sunscreen has earned a permanent spot in my beach bag, which I hope is enough to help me atone for my past beauty transgressions. --Mary Squillace

Travelling without tweezers can be torture -- like when you're gone for a week and you're stuck watching that one errant brow hair get longer and longer. Up until recently, the TSA wouldn't let you pack tweezers in a carry-on (and I only ever travel with a carry-on). So I figured out this workaround: mini tweezers.

The only problem is that tiny tweezers often go missing -- unless, that is, they're in a kit. L'Oreal Paris Brow Stylist Prep and Shape Pro Kit, $14.99, is a great little compact that contains a brow powder, wax, spoolie, angled brush and tiny tweezers. I keep it in my travel makeup bag (which I never unpack and only use when I'm travelling), so I know I'm always covered, whether it's a splinter or that rogue brow hair. Everything else in the kit is also fantastic (the powder looks soft and natural and really lasts), and at a bargain price, you can afford to stash one in every makeup bag -- travel, desk drawer, glove compartment, etc. --Dawn Davis

Confession: I sometimes sleep with my makeup on. And I pop the occasional pimple. But the one cardinal beauty sin I will never, ever commit? Letting my blonde hair turn brassy. Although I am a natural blonde (#humblebrag), I do get babylights or balayage to add a little somethin' somethin' to my hair. So it's necessary to take precautions to ensure my inside-of-a-banana-colored highlights stay that way. My favorite tool in my anti-brassy-hair arsenal? R+CO Sunset Blvd Blonde Shampoo, $29.

One look at the almost otherworldly silver-lavender color of the formula, and I was hooked. That's because the formula contains mica, which gives it (and my hair) high-impact luminosity. It not only preserves my color, it also makes my blonde hair feel incredibly soft and look more vibrant and shiny. And it gently gets my hair superclean, thanks to coconut. Even though it's sulfate-free, it has a rich, luxurious lather that makes for an amazing sensorial experience. Add to that the to-die-for packaging and the fact that it's cruelty-free, and you'll understand how I'm already on my third bottle of this magical elixir -- and why my hair color looks like the inside of a banana and not the outside. --Allie Flinn
