We designed DERMAFLASH COOL to reduce undereye puffiness and dark circles, sculpt the face, and support lymphatic drainage—and it’s clinically proven to do just that. But then something unexpected happened. Our entire team (and professional estheticians) started using the device on their lips. Everyone immediately noticed how much plumper, fuller and more defined their lips looked.
The obvious question was “How does COOL plump lips when it’s designed to depuff?” We rolled up our sleeves to find the answer, and it turns out there’s a scientific reason. Let us explain why COOL instantly gives you a plumper pout.
How COOL Gives You Instantly Fuller Lips
DERMAFLASH COOL wasn’t developed as a lip plumper—it’s a patented sonic facial massage device that uses SonicCool™ technology (which reaches an industry-leading low temperature in seconds) and a proprietary Copper Cooling Dome to boost microcirculation and support lymphatic drainage.
It’s clinically proven to visibly reduce puffiness, improve dark circles, and leave your skin looking lifted and sculpted after just one use. The interesting (and tbh, kind of magical!) thing is the same mechanisms that depuff and sculpt can also visibly enhance your lip volume. It comes down to three key biological effects:
-
Improved microcirculation
-
The cold “rebound” effect
-
Enhanced definition for the lip border
-
Support for natural collagen production over time
Together, these factors work to give you plumper-looking lips—no lip filler (or irritating plumping glosses) required!
The Science Behind Natural Lip Plumping
4 science-backed ways COOL helps to visibly boost lip volume:
1. Microcirculation Boost = Immediate Fullness
Sonic vibration stimulates microcirculation, bringing oxygen-rich blood to the lips. This creates healthy-looking fullness and natural flush of color that’s not caused by inflammation.
2. Cold “Rebound” Effect = Added Volume Boost
Controlled cooling triggers “vasoconstriction” (aka a tightening of blood vessels), followed by “rebound vasodilation” — where blood flow increases after cooling. This rebound effect enhances lip color, creates a natural plumping effect and improves overall lip vitality
3. Depuffing Around the Mouth = Better Definition
Fluid retention around the mouth (perioral puffiness) can blur your lip borders and reduce definition. By supporting lymphatic drainage, COOL helps to reduce swelling around the mouth, enhance your natural lip shape, and make your lips appear more defined.
4. Copper + Collagen Support = Long-Term Lip Plumping
The high-level sonic vibration COOL delivers can encourage collagen production, which can visibly enhance lip volume over time. In addition, copper is scientifically proven to support collagen production. Regular use can improve the look of fine lines on lips + around your mouth and help your lips appear fuller and more youthful
Why COOL Is Different from Traditional Lip Plumpers
Most lip plumpers work by irritating your skin to create a temporary swelling effect. If you’ve ever tried a plumping lip gloss with capsaicin (chili pepper extract), menthol, peppermint oil, ginger or cinnamon, you know how they can sting or tingle. Plus, the results fade quickly, and you’re not supporting long-term lip health.
COOL works differently. It reduces inflammation instead of creating it, enhances microcirculation to optimize your lips’ natural fullness, and supports collagen production. When paired with HYDRAFLASH Active Cocooning Serum, the sonic vibration helps improve product absorption — amplifying the hydrating and plumping effects.
How to Use COOL for Lip Plumping
Your 60-Second Lip Routine:
-
Apply HYDRAFLASH Serum generously over and around your lips
-
Activate your device: Use Speed 1 (press once) for a gentle experience or Speed 2 (press twice) for more intensity
-
Glide along your upper lip border for 15–20 seconds
-
Repeat on your lower lip
-
Use gentle circular motions over the lips for 20–30 seconds
Use COOL in the morning for a natural flush and fullness that makes any lip color look better. We also love using it at night for a calming, restorative ritual—that also happens to give your fuller, plumper looking lips!
The COOL new way to naturally plump your lips
Like we said, we didn’t design COOL as a lip plumping treatment. But when our testing team and trusted estheticians started telling us how it instantly volumized their lips, we paid attention and asked why. Science answered us, and now we can't imagine our morning routine— or our lip routine—without it.
We'd love to know what you notice. Try COOL on your lips and share your experience with us — tag @dermaflash or drop a review. You might just discover a new and unexpected benefit for yourself!
