My Job Is to Test Products, and These Are the 8 Best Makeup Items I've Bought on Amazon

I like to wear a sharp, inky-black cat eye on the regular. Time after time, friends, coworkers, and strangers have asked me the same question: "What eyeliner do you use?" There's nothing that brings me more joy than smugly telling them it's a $6 pick from Amazon. I have been religiously swiping Wet & Wild Megaliner Liquid Eyeliner ($6) on my lids for 10 years now.

MegaLiner Liquid Eyeliner comes in a small tube with a screw-top handle. The applicator, a flexible spongy brush, is easy to maneuver as I glide it across my skin. The harder you press, the thicker the line becomes, so you have a lot of control over the intensity of your look. The formula itself is smooth and matte. All it takes is one coat to get a pleasing obsidian-dark effect.

I tried this Maybelline Makeup Instant Age Rewind Concealer ($6) and immediately fell in love with it. This pick is a bestseller on Amazon, and for good reason.

The super-concentrated formula is infused with goji berry to brighten and illuminate the under-eye area while it covers up your dark circles. The soft, spongy applicator allows the formula to glide on smoothly; the product is evenly distributed across your skin. After a couple swipes, I simply tap the concealer with my finger until it's fully blended. You would never know I have rings under my eyes because they vanish instantly.

This E.L.F. Cosmetics Baked Highlighter ($8) is infused with vitamin E and hydrating jojoba, rosehip, sunflower, apricot, and grape oils to nourish your skin.

Not only do I use this as a highlighter, it's a really pretty eye shadow too. It's one of those products I can keep in my purse for easy touch-ups.

I have short, sparse eyelashes, so hunting for effective mascaras has become a passion of mine. Of all the affordable options, L'Oreal Paris Makeup Lash Paradise Mascara ($6) is my absolute favorite. It lengthens and thickens for a falsie-like effect in just two coats.

What I appreciate about the formula is that it doesn't flake or smudge, so I don't have to worry about it all day long.

Coty Airspun Loose Face Powder ($6) is a loose face and setting powder that helps to minimize the appearance of fine lines, wrinkles, acne, bumps, scars, and other blemishes, giving your facial skin a smoother, softer look.

My best friend's wedding in Costa Rica was fast-approaching, and I knew I'd need makeup that would stay put in the heat all day long. After lots of research, I ordered Maybelline Eyestudio Master Precise All Day Liquid Eyeliner ($7) and I'm so glad I did. I used it both for the bride's wedding makeup and my own face. Through 98 degree heat, there wasn't a single smudge. Even more impressive? We jumped in the pool and it still stayed put. This formula is pretty amazing.

Besides being a budge-proof eyeliner, the design is also easy to use. You can effortlessly achieve a straight line with the pen-like applicator. I gave both myself and my BFF a cat eye in just minutes — no Q-tip corrections needed.

If you're in the market for a new eyeliner pen, this affordable option is the way to go. I have been using it ever since my trip and love it as much as the first day I got it.

If you have sparse or overplucked eyebrows, we have discovered a game-changing product. This Wunder2 Wunderbrow Eyebrow Gel ($17) has gone viral.

Wunderbrow comes in a tube that looks like mascara. It comes in five colors: blonde, brunette, auburn, black/brown, and jet black. The formula is a blend of hair-like fibers combined with pigments that are designed to fasten onto skin and hair. Once you apply it, users claim it can last four to five days. It's totally waterproof and budge-proof — the only way you will get it off is with soap or makeup remover.

This L'Oréal Paris Infallible Makeup Setting Spray ($14) will keep your makeup perfect from morning until night. Its formula includes glycol, alcohol, water, and a form of sodium salt that locks your makeup in place like a seal. It's Saran Wrap for your face! Though it doesn't look or feel like plastic wrap, I promise.
