Amazon Prime Day is officially in full swing, and the algorithm is working overtime to serve up the most unmissable markdowns of the year.
While shoppers are already frantically filling their carts with the best Prime Day TV deals, overhauling their living spaces with massive home and furniture sales, and stocking up on must-have beauty and skincare markdowns, there is one sneaky oral care deal flying under the radar that we just couldn’t gatekeep.
Right now, you can upgrade your daily routine with a dazzling discount on the internet-famous Lumineux Teeth Whitening Toothpaste.
What’s the secret?
Thanks to Prime Day pricing, the three-tube bundle is currently less than a dollar more than the standard two-tube pack.
Yes, you read that right; you are essentially getting a whole extra tube of premium, dentist-formulated whitening toothpaste for just pennies.
Ditch the harsh chemicals and painful sensitivity. Lumineux has taken the oral care world by storm by offering a peroxide-free, enamel-safe formula that actually works. Perfect for those with sensitive teeth, this 3.75 oz daily toothpaste gently lifts stains without stripping away your precious enamel. It is entirely free of fluoride, alcohol, artificial colors and SLS.
Instead, it relies on a dentist-formulated blend of Dead Sea salt, aloe vera, and essential oils to leave your breath impossibly fresh and your smile noticeably brighter. At less than a single dollar more than the two-pack, this three-pack Prime Day steal is the ultimate bargain. Stock your bathroom cabinets before this pricing error-style deal sells out.
But don’t stop at just brushing. If you are serious about achieving that A-list-level glow, pairing your new toothpaste with a dedicated whitening treatment is the ultimate power move. The toothpaste and the strips are designed to work seamlessly together to maintain, protect and accelerate your brightening results.
These viral, best-selling whitening strips are the perfect companion to your any brushing routine. Just like the toothpaste, these strips are completely peroxide-free, enamel-safe and dentist-formulated to deliver visibly whiter teeth without the dreaded “zing” of sensitivity that usually accompanies traditional whitening products.
This box includes 21 treatments; enough to keep your smile shining bright for months. Apply them for just 30 minutes, let the purposeful ingredients work their magic, and maintain your gorgeous new shade with your daily Lumineux toothpaste. I suggest you grab these up while the getting is good.
