13 Bestselling Beauty Products That Will Change Your Routine Forever — All on Amazon

If you're still questioning whether or not setting spray is worth it, you haven't found the right one yet. The product keeps your makeup intact all day long, appearing as though you have freshly applied your face. I have always loved an expensive, higher-end option, but when I ran out, I borrowed NYX Professional Makeup Setting Spray ($6) from my sister's beauty arsenal, and I was so impressed by how well it worked. I used four sprays before I went to the office, and when I headed out for cocktails at 5:30 p.m., I didn't need to reapply any makeup.

I used the matte finish option and it kept any unwanted grease or smudging at bay without taking the glisten away from my highlighter. All you have to do is give the bottle a few shakes, hold it about eight to 10 inches away from your face, and spray it four times. The first two times in an "x" formation, the second two times in a "t" formation.

So how does it work so well? The lightweight formula is a mixture of glycol, alcohol, water, and a form of sodium salt that locks your makeup in place with moisture. Think of it as a seal that keeps you fresh. I have tried plenty of versions, but this particular NYX option has impressed me the most.

I tried this Maybelline Makeup Instant Age Rewind Concealer ($7) and immediately fell in love with it. This pick is a bestseller on Amazon, and for good reason. It has over 4,000 reviews on the site, and 60 percent of customers give it five stars — that's pretty impressive.

The superconcentrated 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.

Finding the perfect black eyeliner is like searching for a needle in a haystack. It seems impossible! That's why I was excited to hear about a new option that's going viral. This Maybelline Master Precise All Day Liquid Eyeliner ($6) is the bestselling option you can get on Amazon. It has over 3,000 customer reviews and about 60 percent of buyers give it five stars. So why are so many people buying this pen?

For starters, the fine tip will give you the most precise line ever. You can easily control how thick or thin you'd like to go. It's also waterproof and smudge-proof thanks to its highly pigmented formula, so you'll have your desired look for as long as 12 hours. The color is an inky black that dries matte. Even eyeliner beginners can master this pen because it's so easy to use. Messing up is nearly impossible.

I love using a toner after washing my face — it keeps my skin even and blemish-free. The one problem I have found, though, is that most toners include alcohol, which can be extremely drying in the wintertime. I would end up with unwanted flakes that were anything but cute. That's why I was thrilled to discover Thayers Rose Petal Witch Hazel Toner ($9). The alcohol-free formula is a bestseller at Amazon, and I totally understand why. It keeps my skin clear without stripping it of moisture.

The product has over 10,000 reviews on Amazon, and a whopping 81 percent of customers give it five stars. That's pretty mind-blowing. People claim that it helps with a multitude of problems including acne, dark spots, the appearance of pores, and hydration. The soothing toner includes rose-petal water, vitamin E, and witch hazel extract.

The tannins in witch hazel extract act as a natural astringent, so they remove excess oil from skin without depleting skin of moisture. The rose water also helps to quench your face, plus it smells amazing. Basically, this liquid is pure magic.

Here at POPSUGAR, we love J.Cat Beauty You Glow Girl Baked Highlighter in Crystal Sand ($7). You won't believe how pigmented it is — people could see your shine from outer space!

I am always looking for ways to have a movie-star-glowing grin, so I was excited to find this popular Active Wow Teeth Whitening Charcoal Powder ($25). It's the No. 1 bestselling option on Amazon, it has over 14,000 reviews, and 77 percent of customers give it five stars.

I decided to put the product to the test myself. Step one was to wet my toothbrush. Then I dipped it into the powder and brushed my teeth like I normally would. (Make sure to rinse your mouth with water really well so no black residue is left behind.) My teeth were significantly whiter after a week of using it.

Wondering how charcoal works? The brand explains it best. "Derived from the highest-quality coconut sources, Active Wow's activated charcoal formula is safe to use for whitening your teeth, while being easy on your gums. Active Wow naturally whitens your teeth, not through harsh dental-grade whitening peroxides, but through the power of activated charcoal, nature's best purifiers, and detoxifiers."

If you have sparse or overplucked eyebrows, we have discovered a game-changing product. This Wunder2 Wunderbrow Eyebrow Gel ($17) has gone viral on Amazon, and for good reason. It has over 10,000 reviews on the site with tons of customer photos that show the impressive results.

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 water-proof and budge-proof — the only way you will get it off is with soap or makeup remover.

Applying the product is quite easy; it only takes a couple minutes. Wunderbrow comes with a brush, but most people like to use their own angled brush to apply it. All you do is fill out your brows the way you'd like them, and you're finished. It's truly that easy.

If you're stumped on where to find the perfect mascara, Amazon is a great resource. Thousands of customers leave honest, helpful feedback that will guide your purchasing decision. We're currently obsessing over L'Oréal Paris Double Extend Mascara ($9) because it's the bestselling option the online retailer offers. It currently has over 400 customer reviews and 70 percent of buyers give it five stars. That's pretty impressive in my book.

So why is this particular choice so good? The tube does double duty; it comes with a nourishing base coat and an ultralengthening top coat. The base is loaded with all sorts of nutrients that keep your lashes strong and protected. The mascara you apply afterward can make your hairs look 80 percent longer than they are. Everyone is insanely pleased with the results and touts that the product doesn't flake or smudge.

Amazon has truly been answering all of our beauty prayers lately. The online retailer is selling this gigantic Shany Makeup Kit ($30) for a steal, and people are taking notice. It's an excellent purchase for beauty beginners or cosmetic-lovers who want to have every color imaginable on hand.

So what does this massive set include? Get comfortable, because the list is pretty long. Inside you'll find lipstick, lip gloss, lip liners, lip crayons, eye shadows, eyeliners, blush, and bronzer. If that's not enough for you, it comes with tools too including eye shadow sponges, makeup brushes, a liner sharpener, an eyebrow comb, a mirror compact, and more. The color variety means that this kit is suitable for every skin tone, which we love.

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.
