We all want to be well-rested, but it does not always happen, unfortunately. Thankfully, there is help from concealer, sunglasses, under-eye gels, and great lighting to combat the appearance of under-eye bags. There's also a TikTok-famous beauty product that has a very loyal following, the Peter Thomas Roth Instant FIRMx Eye Tightener.

According to the brand, this quick-fix product temporarily reduces the appearance of fine lines and crow's feet in the eye area. A Peter Thomas Roth shopper reviewed, "I wish I had found this product years ago! It is the best thing I have ever used for my under eye bags. The first time I used it my fiancé said I looked 10 years younger! I highly recommend it."

And if that sounds too good to be true, another insisted, "The hype is very real. This is an amazing product, does precisely what it promises. Sits nicely under makeup and it didn't move all day. My husband was so impressed he even let me try it on him. The only downside is everyone now knows about it and getting hold of another tube will be a nightmare!" Not so fast. Yes, this is a super in-demand product, but I did manage to track down a great deal.

For a limited time, you can get two super-sized Peter Thomas Roth Instant FIRMx Eye Tighteners and two application brushes for just $38 from QVC. If you bought all of those products separately, it would cost $126. Make sure you always have a backup or give one away as a gift. If you want to see what the fuss is all about, this is the best time to shop.

Shake the tube and apply a thin layer with your brush or fingertips in upward strokes in the eye area and above the brow bone. Keep still for a couple minutes while it sets. Once the product is dry, you're good to go and you can apply makeup—including under-eye concealer.

Pro tip: do not use an oily cleanser or an eye cream before applying this product. Or wait until the eye cream is fully absorbed.
