Smile for Valentine's Day! These Crest 3D Whitestrips are down to $33 — that's nearly 40% off

Valentine's Day is a great reason to shower friends and loved ones with a little extra attention and a trinket or two. But how about showing yourself a little TLC? We often give ourselves the short shrift in favor of making sure everyone around us is happy, but it's just as important for us to feel good from the inside out. One way to do that is to give your look a little zhush — and what better place to start with than with a smile? Crest 3D Whitestrips, 1 Hour Express are on sale for just $33, down from $55 (a nearly 40% off savings), so it's the perfect time to stock up and make those pearly whites even brighter in time for V-Day.

Get on board the Express...and get your teeth a whopping 12 levels whiter.

Why is it a good deal?

At $33, these whitening wonders are nearly 40% off — meaning each set of strips in this 10-day set is only $3 and change. Considering the cost of professional in-office teeth whitening can set you back up to $1000 per session, according to Forbes, a few bucks is, well, a pretty blinding deal. So be sure to snag these Whitestrips now, and your gleaming teeth will match your winter whites.

Why do I need this?

Most of us eat or drink things that leave our teeth a lot less white than we'd like. But this kit promises to lift stains from your chompers' enamel to reveal a smile that's 12 levels brighter in just 10 days. The kit comes with 10 treatments (one per day), and the process couldn't be easier: You just peel, apply and let the strips do their magic every day for just one hour. That's it!

What reviewers say:

Over 1,200 Amazon customers have given these Whitestrips a perfect rating. "I was pleasantly surprised to see that the results were amazing," wrote this happy shopper. "The whitening is especially noticeable, because you see the results in two hours, instead of gradually over many treatments."

"I like this Crest 1 Hour Express because it whitened my teeth without making it look super-fake white," shared a satisfied customer. "The results look natural, and it only took an hour. Just put it on and watched an episode of The Bachelor and I was done! Quick and easy."

One smiling reviewer shared this advice: "I’ve used several of the Crest whitening strips, but this specific box is the BEST! I only used 3 of the strips and noticed a difference in my teeth, by the 6th time I used the strips my teeth were at least 3 shades whiter!"

For some people, it's a total game-changer. "I used Crest 3D Express Whitestrips on my teeth yesterday and am stunned at how well they worked," wrote this final fan. "I am a smoker and daily coffee/tea drinker and my teeth were stained to say the least. I always had to use the 'teeth whiten' feature on myself in my photo editing software. Not anymore, I'm happy to say."

Give your teeth a glow up — literally.
