Lip plumpers are everywhere right now, each claiming to deliver fuller, juicier lips without the need for fillers.

But not all formulas live up to the hype. After testing two of the newest releases, here's the breakdown of how they performed and whether they're worth adding to your routine!

1. The Inkey List Tripeptide Lip Balm

This product had a lot of buzz, but the results didn't quite measure up. Marketed as a tripeptide-based balm that plumps without the usual tingling or stinging, it promises hydration and natural fullness over time. While it's true there's no irritation, the lack of sensation makes it hard to notice any immediate effect. As a balm, it also feels more like it sits on the surface rather than deeply moisturizing. After a few hours of wear, lips can feel dry again.

2. Dr. Dennis Gross Lip Plumper

This one, on the other hand, makes an impression right away. The packaging is eye-catching, designed to look like a syringe, with product dispensed by pumping the bottom. Beyond the fun design, the formula actually delivers — lips feel hydrated, smoother, and noticeably plumper shortly after application.

When it comes to these two lip plumpers, the Dr. Dennis Gross version comes out on top, offering both hydration and a fuller look. The Inkey List balm may be worth trying as an overnight treatment, but it doesn't deliver the instant or lasting impact many expect from a lip plumper. If you're looking for a noticeable difference, Dr. Dennis Gross is the one to beat!
