The Amazon Holiday Beauty Haul Is Back Again With Pre-Black Friday Deals—Find 7 of the Best Discounts Here

These Crest 3D Whitestrips are consistently one of our top sellers during any and all Amazon sales. According to reviewers, they really do whiten your teeth. "[I was only] halfway [through] the box [when I started] seeing a dramatic difference...[Plus,] they stick well to my teeth and are easy to put on. I just run for 30 mins on my treadmill and take them off," one reviewer raves.

We tested the No.3 Hair Perfector, and much to our surprise, our strands instantly went from dull to silky. So we have no doubts about the rest of the mini-sized products in the kit (including the No.0, No.4, No.5 and No.8). Especially since buyers can't stop talking about it. One shares: "I am totally impressed at the improvement in my hair so far. I have already seen less shedding and less hair in the comb. The price is a bit high for the small bottle sizes, but the immediate improvement in your hair makes it worth the price."

Still haven't snagged the PureWow favorite Revlon dryer? Well, you should because apparently, it's all you need to achieve Kate Middleton’s bouncy blowout. Buyers seem to prefer this slimmer design, too: "I was previously using the 1.0...As soon as I noticed there was a newer model, I got it! The 2.0 is narrower and lighter. This makes it easier to use, and my arms don't feel like they will fall off when I'm done. The 2.0 also seems to glide through my hair easier."

Whether you're in the market for a new toothbrush or not, reviewers say it's not a bad idea to grab this electric and rechargeable number anyway. That's because it removes optimal plaque for a more thorough cleaning every time with five modes: Daily Clean, Gum Care, Sensitive, Whitening and Pro Clean. Even better, it has a pressure sensor that alerts you when you're brushing too hard. Oh, and did we mention that you'll get the toothbrush, charger, travel case and two brush heads to switch out every few months?

If you've ever struggled with tough makeup that won't come off, you must give this best-selling hypoallergenic and polyester cloth a try. It's made of millions of tiny fibers that "suction" dirt, makeup and oil in your pores. And it really does, according to this buyer, "I have sensitive skin, so these are perfect for getting mascara off without irritation. I will definitely repurchase them!"

This is what one PureWow staffer said when asked if this set was worth it: "Hell to the yes. To be honest, I used it every other day when I bought it, and I have no plans to stop anytime soon. My hair looks so much better. So much so that a friend asked me if I got a haircut recently, a question I never receive, even if I’m fresh from the salon." If that's not enough to convince you, then maybe the five best-selling products that come with it will.

PureWow readers bought tons of the Waterpik during October's Amazon Prime Day event. This is the cordless version of it, and similarly, it replaces string floss by using a combination of water and pressure to gently remove plaque and debris (up to 99.9 percent of it, y'all). Here's what happened when one hesitant buyer finally bought one: "Not sure what took me so long. The different heads are genius and exactly what I need to get into some hard-to-access areas where crowns are pretty tight, and it is difficult to floss without tearing it up. I love the way that my teeth feel afterward."
